77% Moon

This is my effort from tonight.
ED80 APO, 2x Barlow, D80 Camera, stack of 10 frames.
Focus??

Focus is a bit off, but still a very good shot Jakob. Instead of using the 2x barlow, why not just take a 100% crop from the image, it'd probably be better image quality. Any reason for stacking? I usually just take single shots of the moon, but I'm a newbie when it comes to astro imaging.

WoW!! I can just tell their is more info there. Focus looks reasonable, try processing more. Darks are stacked too, yeah?

Nice work, keep it up!!

On ya, Jakob. Nice to see you posting images.

Dave, much the same as DSOs, you'll end up with greater SNR with stacked images, even of the Moon.

Give it a go next time, and compare. You might be surprised.

Even when shooting at ISO 200? Not much noise there, even on my 1 generation old DSLR!

Dave,
Thanks for the comments. I need Barlow to get focus (need extension tube). Stacking to reduce atmospheric noise (also stacked darkes).
Need more expierience in focussing.

Thanks for comments.

Processing is dark art? I keep trying.
Yes darks are included.

Thanks H.
I have to make Bathinow mask to help with focus.
( but no live view!)

Good on you Jakob.
Will you be coming up for Barambah next month?

Good on you Jakob.
Good to see some images from you.

Keep imaging away as I want to see some more.
