The mask for the color saturation was to narrow. Now the Ha in the border has some color.

Nice done and what a big chip you use. Did you combine the 3 channels or use Halpha as a lum layer and Ha+Oiii+Sii for the color combination?

It looks promising. The 3" looks much better compared to the 2" version

What a monster of glass you have there, a triclops!

It looks like the skybackground is not the same for each color. Can you remove the gradient for each color and not at once in RGB?

Really nice picture.

Thx Paul, getting the colours right is something hard for me in ap. It is try and error.

I moved to an oag this year. It is indeed a bit complicate but the oag from zwo helps a lot when you use a zwo guide cam. All the spacers are made to match it. The v2 oag is good for the price. Until now i was lucky to get a guide star on each object. It is a f5 scope but i can understand on slower scopes it can be tricky. The main reason to move was the flexure on the guide scope. It was to big on my 200f5 with the 1600mm.

This is my 1st try on M101 2 years ago. Not much to tell about it .

With the clear nights of the last days I was able to finish M101. Nearly 13 hours of data. click on the image for the full. ASI 1600MM pro Lum 372 x 60 sec RGB 3 x 90 x 60 sec Ha 24 x 300 sec Newton CFF 200 F5 Avalon Linear & autoguiding

You are right, a little green in the core. Getting the colours right is tricky. Correction done with hasta la vista.

The target was to get 5 hours of Lum .... ASI 1600MM pro Lum 150 x 60 sec RGB 3 x 90 x 60 sec Ha 24 x 300 sec Newton CFF 200 F5 Avalon Linear & autoguiding Software SGPro, EQ mod, PI & PS CS6. Click on the image for the full.
