noice :boogie: but why does one have to stack 104 frames for a moon image? I would have thought the light source is big enough that especially with a 10" a single shot would totally bring out ALL details possible?
the pic here on DA is a bit blurry - is that because it was out of focus or did the frame stacking induce the inaccuracy? are the single frames a bit blurry, too?

Stacking, when done right removes noise and distortions caused by our atmosphere. i use a 7"tablet to zoom in and get my focus as close as possible. Even then there is an ocean of air with waves and tides that drift across my field of view. as one part of the image drifts out of focus another moves back in. The stacking process tries to align and correct the best parts of the best images in a stack of frames.

the Blur is caused by a incompatibility between my 5X Barlow and the camera. I don't see it when i'm looking through the lens, but it shows up when i use it with the camera.

before i crop it, it looks similar to this: [link]

If i had centered it better you would not have seen it.



They vary but I'll post an non-stacked frame some time.
