Description

a learning experience...used reducer as target is so big and the LeXtreme narrow band filter. For some reason the Oiii channel is extremely weak and had bad vignetting when I split it out from my OSC camera data (using APP). Not to waste a night's worth of good Ha data, I processed mostly the Ha channel in this image. Still difficult to process the vignetting. Could it be the back spacing is off? as +1 mm with the filter wheel I just installed? I will certainly have to troubleshoot and keep trying, but I think that ultimately, for this target, a OSC just will not do justice. (just take a look at Rodd's magnificent version: https://www.astrobin.com/s11pjx/H/ )
