Couple of repros from this night. Both over the same 9 min period but one using derotation of images (three 3 min stacks) and the other a  9 min derotated video stack.

1st derotated images :

2nd derotated video :

Absolutely love the fine detail you've got there, excellent. The second one has even more detail jumping out.

Would love to know your process after autostakkert!

Nice reprocessing. I think the derotated video has brought out more details.

Thanks Yelsac.

Wavelets in registax, rgb align & auto colour balance then the rest is in image analyser with extra sharpening, colour vibrance and colour noise reduction. Use frequency domain filter for any other noise control and finish with contrast adjustment. If the limb artefact is popping out I would use some of these steps using the paint selection tool.

Oops! Forgot to mention both images are 1.5x drizzle in Autostakkert.

Both are excellent Stuart and I agree with @Kon that the de-rotated video shows more detail.

Cheers Kostas I'm thinking there is still some field rotation coming through in the 3 min stacks. Might try 2 min next time.

Thanks Geof it does appear sharper for sure.
