I added another hour plus to my Rho with the unmodded 6D and samyang 135, and am still trying to get my head around the advice i had before- I tried each RGB channel adjustment of black point in levels but it got a lot darker.
If someone wants to process the data and give me advice it would be might appreciated.
Plus I had a very quick OSC zwo 294 on NGC 6164-for some reason it was set on TIFS and I can't extract the colour data or debayer so it's B & W. Still- I like the pic for just 8 frames of 180 sec, no calibs.
liking Rho but perhaps could go up a few cranks on the saturation / vibrance?for 6164, have you tried debayering in DSS and changing the debayer pattern? might be worth a shot. but all nice work!
