Second session imaging with my new 662mc and 300p goto. Managed to get a 3x TV Barlow from eBay which was quite well priced.

Still getting to grips with camera settings and playing around with wavelets in registax. Any advice is very welcomed and appreciated, happier with how they’re coming along but they feel a tad blurry. Anyways here is Petavius and Langrenus. Thanks for looking.

The image of Petavius looks good, but you're correct the one of Lagrenus is blurry. About all the advice I can offer is get your AVI files while the moon is high in the sky, and get 5,000 frames per AVI or more. If you can get 1,000 or more usable frames, that will help. Also, use a focal ratio no greater than five times the pixel size in microns. Any more and the image is larger and blurrier. Pay attention to seeing, if it's poor there's no way to get a good image.

Very nice!

 

Looks like you captured the little 'x' near Petavius as well!

 

Suggest using waveSharp 2.0, which is the much improved successor to Registax for wavelets, written by the same author.

Thanks, I have been setting firecap to 5000 frames but the moon was quite low. I live at 53N so it takes forever to get even a little dark now and by that time the moon was probably about 18-20 deg. In the UK so more than likely the seeing wasn't that great lol...My f ratio is 4.9 and my camera has 2.9 micron pixel size so i think with my 3x barlow im at a good spot

Thanks Rob, I'll be sure to check that out

would you say this one infected by Petavius' disease will display it better when arranged at 9 o clock position?
