Just got a new asi 120mc-s, and tried to get a lunar shot last night with my 6inch dob. At 1200mm focal its too zoomed in so if i want to capture a full disk I need to create a mosaic in photoshop. What is the best way to do this?
Last night I tried to let the moon drift across the screen 3 times, with the plan being to stack each video and then align the 3 images in photoshop. If youre confused what I mean, this is the start vs end of the 3rd video https://i.imgur.com/iNjerg3.png and https://i.imgur.com/tc4L8hH.png.
That worked for the first 2 videos but not the 3rd. And for the 2 first videos, there were some stacking artefacts that looked really nasty with sharpening.
Video 1 stack = https://i.imgur.com/12XMAtt.png
Video 2 stack = https://i.imgur.com/gSY4jiz.png
Thos ones stacked fine, but when I went to stack the 3rd I kept getting really bad miss stacks. like this https://i.imgur.com/TkusPLY.png No matter what settings I tried I always got bad stacks with 3, and the patterns were consistent. Out of curiosity, I 'stacked' (select 1 frame in autostakkert) the first frame to see if it had corrupted and this was the result https://i.imgur.com/A9nWrdg.png
After seeing that I then rejected the first 10 frames but still had the same error. And then after that I went a cut the first 10s of the video off but that also had the same problem. The only thing that seemed to change how good the stacking was, was making less APs and making them larger. This final image was done with 2 APs https://i.imgur.com/gMDlEHX.png
I had a look through that video and couldn't find any massive jumps/corrupted frames. Running through PIPP doesn't work because it crops and registax just gives a worse result.
If anyone has any ideas what happened with that 3rd video and how I can avoid it, that would be greatly appreciated. If there is a better way to do this sort of imaging, please tell me! I would also like to be able to remove the stacking artifacts in 1 and 2.
