tooth_dr Posted October 22, 2020 Share Posted October 22, 2020 1,000 light-years away, this dusty molecular cloud is part of a dark nebulae complex within Cepheus Luminance with Epsilon 180ed, RGB with ED80 This is the first time I've really struggled using the ED80 to get colour data. I've attached the LRGB version, the L and RGB data. I've since devised a more elaborate way of aligning the two scopes, so the misalignment seen here wont be an ongoing problem, and there was some sort of cock up with the guiding losing a star, and then moving frames. Isnt there usually something with AP!! CC welcome. Adam 29 Link to comment Share on other sites More sharing options...

souls33k3r Posted October 23, 2020 Share Posted October 23, 2020 What a brilliant image Adam. Not overly stretched, beautiful star colours... Just perfect. What's your bortle scale if you don't mind me asking matey? Link to comment Share on other sites More sharing options...

I do have an SQM I just haven’t got round to fitting it yet 😫 1 Link to comment Share on other sites More sharing options...
carastro Posted October 23, 2020 Share Posted October 23, 2020 Very nice Adam. This one is on my To Do list, but not yet had an opportunity to do it properly, except with my Samyang lens (together with the Shark) where it was far too small. What amount of data did you collect for the luminance and RGB sets? Carole 1 Link to comment Share on other sites More sharing options...

I can not even think of imaging anything remotely rgb in my bortle 8 skies. 🤦♂️ Link to comment Share on other sites More sharing options...
ollypenrice Posted October 25, 2020 Share Posted October 25, 2020 Super image. Really good. The colour looks stronger in the LRGB than the RGB, maybe because you continued to push the colour after or during the combining with L? Olly 1 Link to comment Share on other sites More sharing options...
AbsolutelyN Posted October 29, 2020 Share Posted October 29, 2020 Fantastic images as always. How are you aligning the two scopes? Are they on the same mount or two mounts? Just curious as been thinking of a dual setup for a while but doesn't look easy. 1 Link to comment Share on other sites More sharing options...

I did push the colour during combining, perhaps I should have done it first!? Thanks Adam. Link to comment Share on other sites More sharing options...

What amount of data did you collect for the luminance and RGB sets? Carole Hello Carole, sorry for the delay in replying. The luminance data was 85 x 3 minutes = 4 hours 15 minutes And the colour as follows: red 18 x 5 minutes, green 18 x 5 minutes, blue 17 x 5 minutes = total RGB = 4 hours 25 minutes Total integration time was 8 hours and 40 minutes. 34 minutes ago, AbsolutelyN said: Fantastic images as always.

The scopes are on the same mount, and are aligned using a very rudimentary system. I dont have access to a lot of machines, so I make do with a pillar drill, a bench grinder, a set of hand files, and cheap set of threading taps. I have also bought a set of feeler gauges to do the final vertical adjustments. I'll post some photos later, its functional but not pretty.

Well, the result's great so there's no problem. But I do push the colour at the RGB stage myself, then maybe again later or during the iterative addition of Lum.

I do plan on continuing my process of using the ED80 for lum data so I think I need to work on that aspect of my imaging. Link to comment Share on other sites More sharing options...
