On Sunday the 20th of April, I set the scope up to do some solar imaging.<\/p>\n

There was a nice trio of prominences on edge of the disk the day before, so I thought these may have shown some nice changes since then.<\/p>\n

One had faded completely, but there appeared to be quite a bit of detail in the remaining two. As I started to take images, I could see some rapid changes in their shapes, even during the short duration of the video capture. It immediately struck me that these features might make a nice solar animation if a series of images were taken over a period of time. The quick process shown below bore that assumption out, showing quite a lot of detail.<\/p>\n

\"\"<\/p>\n

So starting at 07:23 am GMT I captured a 60 second avi.
\nI then re-centred the image and repeated the process over and over again.
\nI finally finished at 10:06 am GMT, a\u00a0mega two and a half hour marathon.<\/p>\n

As a result I ended up with saving 109 videos.<\/p>\n

Then the fun really began.
\nI processed each captured avi with Autostakkert! to create a single image from each one.
\nI then sharpened each image, using Registax.
\nUsing Photoshop I sharpened each one again, with further processing to reveal some of the fainter details.<\/p>\n

Once this was accomplished, I loaded all the images into a single stack.
\nI then painstakingly aligned each layer with the one below.
\nOne I was happy this was achieved as well as possible, I created a timeline to scroll through the images to create the time-lapse.
\nA few more tweaks were required to make sure that this was as smooth as possible.<\/p>\n

When I was happy, I then exported the layers as an animated GIF.
\nThis whole process took me more-or-less the whole day.
\nI’m never going to get that day back.<\/p>\n

But BOY, as you can see below, it was definitely worthwhile making the effort.
\nThe seeing was a bit iffy in a few of the images, but the activity can easily be seen.<\/p>\n
