Nice capture Jordan!

Thanks George! Does the software graph those tables? I go number blind with those blocks of data.

I am aware of critical sampling (courtesy of Malveaux) and try to adhere to it. I assume though that this could be dealt with a barlow / telecentric to reach the desired focal ratio, but it would increase the focal length of the system and reduce FOV to an unacceptable size. It could, but the disk ...

1. You stop down your scope. Why do that and reduce resolution? It is for critical sampling. If not would be under sampling, which might offer an decrease in exposure time but offers no increase in resolution from optimal sampling. Think of optimal sampling as sitting reading a news paper or magazi...

More cool scopes! Nice instrument Chris!

What's the focuser like on the scope?

They look impressive Kevin!

Cool and grey here today, so nice to see what was going on. The sun looks quieter again now.

Always nice to see your work Peter!

That's pretty cool Paul!

These are nice results James! Considering this is with an alt az mount it is even better. Cloudy for me today so good to see what is going on.

Nice to see your images Eric, cloudy all day here!

Nice shots Chris!

Nar, in the week they stay in bed when I have to get up for work. They've both gone back to bed now after their breakfast.

Hi Stefan.

A zwo 178mm will be a good match for the scope.

Always love your cinema Warren!

They still look good Leo! Viewing them less than full size in the forum thread compensates for any apparent oversampling.

A super set of images Pedro!

Way cool!

Thanks JAmes, didn't finish work till really late tonight so no sun for me today, nice to read your report though. I may get an early morning shot if i'm lucky before work.

Thanks Andrew, no sun for me today,

Hi Mark, A scientific approach wins the day. This is a really nice demonstration of the balance to be struck between some important factors determining the ability to resolve detail. My approach is to try to set up each of my scope/Barlow/camera (pixel size) combinations to operate under ‘critical ...

Thanks guys, cloud and rain here this monday morning.

These came out really well Brian, I know the feeling of work imposing constraints, sometime you just gotta image regardless of what the seeing might be like!
