tooth_dr Posted November 19, 2019 Share Posted November 19, 2019 (edited) LRGB image from the past couple of weeks. The camera was changed and scope was moved between exposures - the downside to a reflector Had to crop it a bit too. It's looking like rain for a few days, I just want to practice on this data. I'll need to address the star sizes soon ( I keep ignoring them) if I want to progress in this hobby, but even getting a decent RGB combo was an achievement for me. Looks a bit soft. Adding Lum to RGB I'm struggling again. I had a lot of luminance but limited colour data. RGB was 5 x 300s per channel. A small 2 x 2 panel mosaic was really do this target justice. Comments welcome Adam. Edited November 19, 2019 by tooth_dr 25 Link to comment Share on other sites More sharing options...
Adreneline Posted November 19, 2019 Share Posted November 19, 2019 (edited) I like the understated colours Adam - just a hint of blue and realistic coloured stars. Very nice. This is a target I have shied away from so far cos' I'm sure I will never do it justice. One day - maybe.

I’m never sure how far to push the colour saturation, it’s hard to find that balance. Link to comment Share on other sites More sharing options...
Hallingskies Posted November 20, 2019 Share Posted November 20, 2019 That’s a great effort. I’ve never been able to tame the stars and retain the nebulously details as you have done. 1 Link to comment Share on other sites More sharing options...

What camera are you now using for these latest images with the Epsilon Thanks John. I just bought an Atik EFW3, so I figured it was just make more sense to use the Atik 383L. I've it spaced to perfection now so I wont be touching it!! Link to comment Share on other sites More sharing options...

I've it spaced to perfection now so I wont be touching it!! So with the EFW3 and the 383 you can get a backfocus of 55mm? Are you not using an OAG? As that was why I changed from Atik as I wanted to use an OAG and Atiks FW was too thick? Link to comment Share on other sites More sharing options...

As that was why I changed from Atik as I wanted to use an OAG and Atiks FW was too thick? Hi John. With the Tak I'm after a backfocus of 56mm (+0.7mm to account for the filter thickness). This was achieved with some spare space, so I ended up needing a spacer. The thickness of the EFW3 is 21.8mm and the backfocus of the camera is 17.5mm, this gave me 39.3mm. So I had roughly 17.5mm to fill in using an M54-M54 adapter, and an M42-M54 adapter. Link to comment Share on other sites More sharing options...
Jkulin Posted November 21, 2019 Share Posted November 21, 2019 Ok Adam, so you weren't able to use an OAG? That was one of the main reasons I switched to Moravian because of Atiks FW thickness. Link to comment Share on other sites More sharing options...

I never intended to use an OAG so that question I just dont know the answer to. Link to comment Share on other sites More sharing options...
ollypenrice Posted November 21, 2019 Share Posted November 21, 2019 Lovely. Personally I'm a strong colour enthusiast but this often gets me reprimanded on the French forum, though I seem to get away with it here! What's the LRGB issue? When you have strong luminance it can easily dilute out the colour. In Photoshop I address this by adding only a low opacity of luminance, increasing the colour saturation of the bottom RGB layer and then putting a slight blur into the top L layer before flattening and repeating the process. On the final, full opacity iteration of luminance addition I omit the blur. Olly Link to comment Share on other sites More sharing options...
MartinB Posted November 21, 2019 Share Posted November 21, 2019 This is a very fine idea. I'd stick with getting it wrong if I were you! 3 hours ago, ollypenrice said: Lovely.

There is no correct level of saturation, or artefact free sharpening/noise reduction come to that. May be the "group think" is a little more accommodating and less puritanical on here. 1 Link to comment Share on other sites More sharing options...
