Path of Comet Leonard for December 2021

As Comet C/2021 A1 (Leonard) heads further eastwards over the next two weeks, it will start getting lower in the eastern sky in the early hours of the morning before dawn.

But it is bright enough to be viewed in binoculars or a small telescope at the moment.
It MIGHT even become bright enough to be seen with the naked eye (fingers crossed!).

The Comet passes the bright globular Messier 3 between the 2nd & 4th of December.
I have included details of that here:

My video about the prospects of the comet is posted on YouTube:

The maps created using Sky Safari below show the path of the comet until the 12th of December.
I hope that they help you to find the comet.

1st – 7th of December:

7th – 12th of December:



Comet Leonard Passes Globular Cluster M3.

As Comet C/2021 A1 (Leonard) continues to brighten (Fingers Crossed!) it is now starting to get lower in the morning eastern sky.

The map below shows the path it will take in the sky, passing north of the bright star Arcturus on the 6th of December.
(All maps produced using Sky Safari).

Wider angle maps to help find the comet over the next couple of weeks have been posted here:

The comet passed by the Whale & Hockey Stick Galaxies on the 25th of November as can be seen in my image below taken that morning.

But the show doesn’t stop there.

Comet Leonard will pass right across the front of the bright globular cluster Messier 3 on the morning of the 3rd of December, which will make for a great observing and imaging opportunity.

We will have a few opportunities to observe the comet, close to the cluster from the morning of the 2nd until the 4th.

On the morning of the 2nd of December at 02:00h UT, the comet will be located to the west of the cluster.
This should make a nice image for those who can obtain a fairly wide angle view.

The next morning (4th December), at 02:00h UT, the head of the comet will be butted up right against the cluster.
The comets extended coma should surround the clusters stars.

The comet will be moving eastwards across the front of the cluster.

By 06:00h UT, a little before the sky starts to brighten in the oncoming dawn, the comet’s bright nucleus should have cleared the cluster.


The next morning at 02:00h UT, the comet will have moved a bit further away, but the tail should still be fairly close to the cluster, making for a great view or another amazing image.

The comet will then move further down, getting lower in the sky each morning.
It will definitely be worthwhile setting your alarm and keeping an eye on the weather and get out and keep and eye out on what the comet is doing.

Wider angle maps to help find the comet over the next couple of weeks have been posted here:

Comets are always so unpredictable, and constantly surprise us, and I’m guessing Comet C/2021 A1 (Leonard) will be no different.

Have fun.



Comet C/2021 A1 (Leonard) is Brightening.

Comet C/2021 A1 (Leonard) is brightening nicely.
Last night it was passing the two NGC galaxies, The Whale and The Hockey Stick.

So as it was clear, despite the full Moon, I managed to get a few images with a mono CMOS and a colour DSLR.

I combined the images and this is shown here.


If you want to know where to find Comet Leonard see my guide here:

The Planetarium was back in a school!

After what seems such a long time, the planetarium finally visited a school on Wednesday.
I was a bit apprehensive about it, but the staff looked after me and the children were fantastic.

It was so great to hear them laughing, answering questions and their excited faces were an absolute picture of delight.

How I’ve missed all this.

Here’s to lots more days in schools.





ASIAIR Pro Plus – First Nights Out

So, the big question is:
Does the External aerial on the ASIAIR Pro Plus (AAP+) make the WiFi Signal Stronger?
From what I have seen on the two clear nights I’ve had, that is a resounding YES!

I connected to the AAP+’s WiFi and using the ASIAIR App managed to get it Activated with no issues.
It told me to connect to the Home WiFI and download the activation to the device from the Internet.
I then re-connected to the now activated devices WiFi.
I then used the AAP App to connect the AAP+ to my home WiFi, and set it into Station Mode.

Once I did this, it picked up an IP address on my home network. So far, so good!

I then tried using the Android Emulator LDPlayer on my PC to connect using the ASIAIR app.
It could not connect directly, but as I had made a note of the IP address in my home router, I added this manually and everything was connected.
After doing this, it connected first time, every time.

This was also true for any of the mobile Android devices I used which were connected to my home network.

I put in all the details of the accessories attached. All went really smoothly.
Now just got to get it all attached to my setup, ready for action.

It was clear the night I received it, so although it was a bit murky, I thought I’d have a go anyway and put it thorough its paces:

Once problem I had is that the slightly different configuration of the AAP+ made it a little bit more awkward where it was mounted on the finder shoe. So I have now ordered the clamp so I can mount it in a better position and orientation. Plus it’ll be more secure, behind the guidescope on the top dovetail.

Once set up, all the accessories were connected and with no hitches it was very quickly up and running.

The EQDIR cable connected to my EQ6 and I was also able to connect to the mount using EQMOD with SkySafari. This software often has more up-to-date comets in the database than the ASIAIR App, so is an extremely useful addition to the weaponry when tracking down your prey.

All I had to do now was wait for it to get dark.

I could just about see Deneb in the bright twilight, so I sent the scope to it.

As I had come to expect from my old AAP, it dutifully pointed the scope near to the star, where I stopped the slew and was able to manually move the scope onto the star, so I could start to get the main camera and guide camera focused.
Once done, I took another image, got the AAP+ to plate solve, then GOTO Deneb again.
It slightly adjusted its position and then displayed an image of Deneb, right slap-bang in the centre of the screen.

So far, so good.

Once it was dark enough, I took the scope on a quick tour of a few objects that night, to test the GOTO capabilities.
All the searches were performed flawlessly. Each object was perfectly positioned each and every time after a quick plate solve.

Holding down the mouse or finger on the screen bought up the GOTO circle.
This allowed me to easily reposition the object on the cameras field of view when required.

The auto-focuser worked really well, so I refocused using the Hydrogen Alpha filter.

I set it up to tell the camera to chug out some quick Ha images.

Preview, Plan and Autorun Modes worked extremely well.

The multi-star auto-guiding was an absolute dream.

Cassiopeia Ghost:

Crescent Nebula:

Afterwards, I noticed a few problems that caused by the user (ID10T error) that I needed to fix.
(As you might be able to tell from the Crescent Nebula image above).

So a few nights later on the next clear night, with a bright gibbous Moon, and another murky night, I decided to concentrate on a single bright cluster.

This was Messier 11, the Wild Duck Cluster in Scutum.
I took LRGB images of the cluster and the results, considering the conditions, it all came out quite well.
I’d never seen the V-shaped flight of ducks in this cluster until now.

So what do I think about the AAP+?

The AAP Pro completely transformed my imaging.
I have absolutely loved it since I was first given it to have a play with this time last year.
I loved the functionality that it has so much, I just had to buy it.

The AAP+ can only build on that as ZWO start to add new functions.

This will be the way I will be taking my images and tracking down comets from now on.

Like the AAP Pro, It Just Works!

I didn’t experience any signal drop-outs on both evenings.
The external aerial definitely makes the signal a lot stronger and gives a much more stable connection on my home network.

The AAP+ was accessible and controllable from all my mobile devices and LDPLayer on the PC across my home network, wherever I was in the house or garden.
This will makes it invaluable for me for live-streaming images of objects across the Internet.
Just to note, my home WiFi has boosters to reach to the bottom of our fairly small garden.

One problem I did encounter was when I was using an older Power supply.
When all my devices, camera, focuser etc, were connected, the AAP+ would not start properly and its WiFi light did not come on.
Once these were removed, the AAP+ started OK and the devices could be reconnected and looked like they were working.
But this was down to the power supply being used not supplying enough power, not the AAP+ itself.
Make sure you use a recommended power supply, not one from well known general stores online shops or flea markets.
These frequently cause the device to run erratically, despite being labelled as the correct voltage / rating etc.

Talking of Power, There seems to be some confusion as to whether or not you can power a mount through one of the power ports.
Some people haven’t reported experiencing any problems when they have done this.
I originally did this, but have since have moved to powering my AAP+ and mount separately, just in case it causes any problems or damages the AAP+ or Mount.

Features I haven’t tried with the AAP+
Polar alignment. But it worked extremely well with the AAP Pro.
Video Mode.
Live Mode. (I much prefer to stack my subs after the event anyway, but this may change…).

Is it worth getting one?
If you haven’t got one and have ZWO Cameras, or you have the original AAP, then it is definitely worthwhile getting one, or upgrading.
If you already have the AAP Pro and not experiencing any connectivity problems, I do not think that the AAP+ offers that much in additional features from an upgrade as yet. BUT! The device has had some significant changes under the bonnet.
This should allow ZWO to make additional improvements and add lots of new features as it develops the product further.
It does look like they are extremely keen to do this going forward, so it will only be a matter of time before some new functions are added.

All versions of the AAP only work with ZWO cameras and many DSLR’s.
If your CCD or CMOS cameras are of another make, they will not work.
Is it really worth getting one and having to change your cameras to achieve this sort of functionality?
In this case a different solution will probably work best for you.
A list of tested DSLR’s is shown here:

So, if you want one, when are they expected to be available?
ZWO are reporting that pre-sales placed with them will be sent out sometime during November.

It is not likely to become available to astronomy stockists such as First Light Optics until later in the year.
So if you are interested in getting your hands on one, keep a look out for when these do start to become available.

If you have any questions that you think I might be able to help with, please do give me a shout, as I’m happy to help others if I can.

Fun in The Sun – 18th September 2021

I always get excited when an active sunspot approaches the solar limb.

You just never know what delights it will give you using a Hydrogen Alpha setup.

On the morning of the 18th of September it was very clear, so I set up my scope and plugged in the Quark.

Even before the Quark was anywhere near set at the correct temperature, it was quite clear that there was an extremely bright prominence visible on the limb.
You cannot usually see prominences in this setup, until the Quark is close to reaching its tuned temperature.
So I quickly realised that this might give some really great results.

All came to temperature and the view was incredible.
Undoubtedly, these were the best views I have ever had with my own equipment.

This was Active 2871 before it rounded the solar limb to move into view from Earth.

I took a few images,  a couple of which I have posted below.

Just look at that plasma following the lines of the magnetic field around them.

While taking a couple of different exposures to make a mosaic to get all the action in one image, I noticed a surge prom starting to develop.
Here is one of the images I took of it.

As things looked extremely active and moving fairly quickly, the impulse to capture an animation of all this going on was now far too strong.
I took loads of images 2 minutes apart, and managed to capture 30 minutes of action before the clouds to end my fun.
I then spent a good few hours processing each image and putting the animation together.
I have added this below.

Boy, there was so, so much going on here.

ASIAIR Pro Plus – First Impressions

A couple of weeks ago, I was lucky enough to be accepted as an ASIAIR Pro Plus Experience Officer.
What the heck does that mean?
Well, having used the ASIAIR Pro since last year, the manufacturers ZWO were looking for people who posted online content to receive one with a big discount and test out their new ASIAIR Pro Plus. So how could I refuse?

After it taking a bit of a tour round Asia and Europe, I eventually received mine and have now taken it out twice to see how it performs.

So here’s what you get in the box:

Of course the Plus has the external aerial, which everyone is hoping will solve the weak WiFi signal.

Included are a USB cable and a few power cables.

A USB stick was included with the previous version, but not with the Plus.
But you can still use a USB stick to transfer files from it.

The Plus is slightly bigger that the Previous AAP Pro.
(Thanks Stu, now you mention it looks like Spiderman’s Router, I just can’t drop that impression from my mind).

It has the same USB3 and USB2 ports and Ethernet ports.
In this view you can also see it is a bit thinner.
It is also a little it lighter:

The Power Ports have lights above them, so you can see when they are powered up:

On the other side of the Plus there is now a USB-C and an DS Card slot, both used to transfer files:
Annoyingly, if you are using the securing holes to attach the dovetail foot or the clamp, it covers these up.
It would be really annoying to have to remove this each time to use them.

So that’s what it looks like, the next thing was to put it through its paces and see how I got on with it.
I managed to get two clear nights since it arrived.
I will post a following blog entry to let you know how I got on.



Perseid Meteor Fun

This is what I just love about this wonderful hobby. You never know where an image or social media post will take you.
I have found yet another rabbit warren into which I can lose myself.

Anyway, after a battle with my camera, I finally got my All-Sky Camera working properly in time to try and capture some meteors from this years Perseid Meteor Shower. The problem I had was that it produced a very grainy image, with lots of bright coloured speckles across it, from the camera I was using.
It was my old ZWO ASI120MC camera I used for imaging the planets.
Getting a good dark frame image to subtract has been a complete nightmare.

But I finally got it working and producing some reasonable images I could use.
So while we were away in The Elan Valley in Wales where I was hosting a Perseid event, the camera was faithfully capturing images for me, when it was clear here.

The camera caught a couple of meteors that week, which I posted on social media.

This image of a meteor captured at 23:43 UT on the evening of the maximum on the 12th of August showed a very bright Perseid at 23h 43m UT in the north western sky, passing close to the handle of The Plough.

This then started a chain of very interesting events.

After posting this image on Facebook, one of my friends from Breckland Astronomical Society, re-posted it on their Facebook page.

Chris Bailey, who has a monochrome All-Sky Camera, posted his image taken at the same time, which had clearly captured the same meteor.
Notice how the position of the meteor in the sky is different, due to the distance between our two observing sites.

I tried to superimpose the two images to show the shift on perspective below.
Chris’ meteor is closer to the horizon. Chris was located East of me in Suffolk, so must have been further away from the meteor.

Another member of Breckland AS, Dan Self, using simple trigonometry (Simple that is, if you were taking it all in at school, unlike me!), and knowing our two locations, calculated the height, position and distance of the meteor from us both.

His calculations can be seen below.

These showed that the height of the meteor was between 70 miles and 52 miles high, top to bottom of the trail.
It was 167 – 163  miles away from Chris, depending on which part of the meteor trail you measured, which was 25 miles long.
And 107-108 miles from my location across the ground but as it was at that altitude, that came out as a distance from me of 128-120 miles.
The meteor would have came across the sky almost directly above The Peak District.

Knowing this, I popped off a message to Patrick Poitevin, who has meteor detection cameras and lives in Tissington, right in The Peak District, to see if any of his cameras had captured it.

The meteor, being so high in altitude from Patrick’s location, was not picked up by any of his cameras.
But it was captured by other cameras in the UK Meteor Network and logged, as can be seen in the image below, where it goes right through The Plough.

When they tracked the path of the meteor, it was slap bang right over The Peak District as shown in their image below.
Absolutely awesome work by Dan there.

Full details about that particular meteor from The UK Meteor Network Archive is shown here:

Now, I might investigate to see how you get set up to join in with this meteor network.


A Monster Comet – 2014 UN271

There are many stories going around the internet about a “Monster” Comet which is making a beeline for our solar system.
Called 2014 UN271  (Bernardinelli-Bernstein), this comet is currently 20 Astronomical Units (20x the distance of Earth) from The Sun.
The comet is absolutely huge, possibly over 100km in diameter.


Comets that big have the potential to make extremely bright apparitions, like Comet C/1995 O1 (Hale-Bopp), which put on a fantastic display in 1997, or Comet C/2020 F3 (NEOWISE), which gave a very fine display in 2020.

2014 UN271 is heading towards us, but will take quite a few years, reaching its closest to The Sun (Perihelion) in January 2031.
This has caused many stories to come out about us seeing a fantastic comet at that time.
Why there has been a sudden flood of interest, I do not know.
We have known about this object and its orbit since 2014.

Unfortunately, this is never going to give us a great show, as even at its closest, the comet is not going to get any nearer to The Sun than the planet Saturn.

As a result, it will not be close enough to The Sun to be heated properly to make it very active for it to produce a lot of gas and dust and a large coma.
Plus being such a long way from Earth, this will reduce its apparent brightness even further.

It will be extremely interesting to see how it behaves, being a brand new Oort Cloud comet, but you can ditch any idea of seeing a real spectacle.

From an amateurs point of view, it is only going to appear as a faint smudge of light at its very best. It will only be visible in large telescopes and revealed using deep long exposure photographs.

UPDATE 1st October 2021
Current thinking is that it won’t even get as bright as Pluto as seen from Earth, possibly around 17th magnitude.

UPDATE 7th July 2021
Some reports suggest that the comet may not be as big as first thought, as it may have a large coma already which is making it look bigger than the solid nucleus.
That’s what I love about comets, they always throw surprises.
So I will be following this story as it develops.

Perhaps they should send the proposed Comet Interceptor from ESA to get a better look at it?
This comet probe is due for launch a few years before in 2029.

Unfortunately, even the Comet Interceptor will not be able to explore this celestial visitor for two reasons.
This cometary probe will be using solar panels to power it.
At the nearest distance of the comet, these panels will not supply enough power to keep it going as it will be too far from The Sun.

Plus it would take a number of years for a probe like this to match the comets motion in space, to keep up with it.
We saw this with the Rosetta comet probe a number of years ago, which took over a decade to reach Comet 67P.

An Experiment in Processing

I am constantly looking at different methods of processing images to develop better workflows and improve my images.

This is so I can see what different things work, and continue discovering new ways of processing images to improve the images.
When do process my images, I always try as hard as I can to make them look as natural looking as possible.

I always instil in people who attend my astrophotography workshops NOT to over-process their images.

As you can imagine, being such a purist, it really drives me mad to see so many really over-processed images popping up online and on social media, with all sorts of processing artefacts visible. But I am starting to think that I might be missing a real trick here.

In the early hours of the 20th of April, I was coming to the end of a short imaging session to capture Comet Leonard and some mono images.

I was desperate to try and get some RGB data to attempt a colour image with the setup I am trying out, but was short of bright objects to try it on.
I could see that Hercules was fairly high by this time, so despite the gathering murk, I though that I’d grab a few shots of The fantastic globular cluster M13.

I quickly rattled off a few shots using the three different coloured filters with the ZWO ASI183MM mono camera.

Now onto the processing.
It was never going to be a show-stopping image under those grotty conditions, but at least I got some RGB data to play with.

So, how did it turn out? The results are below.
The top image is a standard process using my tried and trusted technique.

The bottom image takes the processing a bit further, enhancing the brighter stars and their colours.


The bottom image, to my mind is well over-processed, but I felt that it does have something about it.

As an experiment, I thought I would put it to the test and posted them both on social media, asking which image folks preferred.

Apart from a few that liked the more natural looking top image, the vast majority of people who responded favoured the bottom image.

So this really was a eye-opener for me.
Does that mean I need to over-process my images to get more likes and shares, or should I stick to my principles?

What do you think folks?

My first image of Comet Leonard and Crescent Nebula

Being so busy lately,  I’ve somewhat neglected my blog for a while, so it’s time to take it up again.

On the evening of the 25th of May, we finally got prospects of a reasonably clear evening.
Despite the late time of the sky getting dark, and an almost full Moon, I decided to get the scope set up and see if I can capture an image of Comet C/2020 A2 (Leonard).

This comet could give us a great show later in the year. (Where have we heard that before?).
See my YouTube video below describing what we might expect from the comet.

I contacted my mate Kev, so he popped round to see the ASIAIR in action.

I had another problem with the Off Axis Guider, so ditched that for this session, guiding with a 50mm guide scope.

Got all set up before The Moon got too high and bright, then sent the scope towards Merak to calibrate the position.
I then used Sky Safari to GOTO the comet, which wasn’t located too far from that first magnitude star.
We quickly identified that we were looking at the correct star field so the comet should be right in the centre.

So I rattled off a number of short 30-second subs, not knowing how fast the comet was moving.
(I will do longer subs next time).

Once stacked, I got this very nice image below, showing the comet near some very faint galaxies.
The comet is about 16th or 17th magnitude, so has a long way to go before it gives us a good show.
But I was well pleased to capture the comet so early in the year.

Once I finished that, The Moon was getting extremely bright, so I switched to the Hydrogen Alpha filter and went to the location of NGC6888, The Crescent Nebula in Cygnus.
The resulting image is shown below.

All in all, it was a very enjoyable evening, and great fun to catch up with Kev again.

THE ASIAIR PRO – First Impressions

I have been fortunate in having an ASIAIR PRO very nicely sent out to me by First Light Optics.

It will give me a chance to have a play and review it for you.

First impressions are on the few clear nights I have had to test it out, is that it will be a game-changer in what I can offer, especially online educational streaming.

I have  uploaded my first impressions review on YouTube.

I’ll do a more more detailed review and run-through to follow, when we do get a clear night.

Comet C/2021 A1 (Leonard) could be good later this year.

Comet C/2021 A1 (Leonard) is causing some excitement as it HAS THE POTENTIAL be quite bright later this year.
