Lots of contrast there Lou!

Looking good there Robert! Heavy showers down here today.

Lovely cinema as always Warren!

Thanks Andrew!

Hi, what kind of Herschel wedge would you recommend for imaging only use with my C9.25 (with D-ERF)? Is there a benefit of 2" versions like Baader or APM in comparison to 1.25" versions? I already have a 2" Lumicon OIII Filter that i want to use with the wedge, so i guess the 2"...

They came out well Peter!

Does it need to be pointing at the sun to get the red reflection?

You got a nice hour in there James, solar just hasn't been possible for me this week with work and weather both not aligning.

Good results in the gaps Rainer, i've not had any gaps at all this week.

Very nice Arne, it has been cloud, showers and rain here all week, so nice to see what is happening on the sun.

Nice set of images and animation Warren!

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!
