Hello Bill, I mostly use free software.
Simple solution: download Registax (free) and load your pictures into it, let it stack them and then play with wavelet sharpening until you like the result.
Less simple – what I actually did:
That was 21 shots using a Canon 10D (ancient) on my scope at 100 iso and 1/100 and 1/250 second. The scope was tracking at lunar rate, but i doubt this made much difference. I had focused the scope with a bhatinov mask and it was well cooled down – I had been outside for three hours at this point.
I used RAW and balanced the images in Raw Therapee before doing anything and saved as TIFFs. (If they had all been the same exposure I would not have needed to do this as PIPP would have accepted the RAW files).
I then loaded the TIFFs into PIPP which automatically centres the image (among other things).
PIPP produced a new set of cropped tiffs that I put into Autostakkert! 2 which aligns them and produces a final image. I used all 100% of frames as I could see there were no 'duff' ones.
I then used Corel Paint to reduce the gamma to about 0.5 to stop the highlights bleaching. You can use many image program,s to do this sort of contrast adjustment.
Finally, I used Astra Image 3 to apply Lucy Richardson Deconvolution which worked brilliantly on this image (if you download old version 3 it comes with a licence activation code). You have to play with the settings to hit the 'sweet spot' that matches the lens and conditions and any focus error, but I think that the clear conditions and good focus set me up for success.
