Hi,
so this is probably me still learning the ropes, but I had the following issue:
I am currently collecting data for M33, first batch was(1h of L/R/G/B each at F5.5). After combing and photometric color calibration of R/G/B, I see clear hints of the various Ha regions, some very strong, some fainter. The image at this stage has a slight green tint. After stretching etc I would then run SCNR (green) - which unfortunately erases most of the Ha signal (except the very strong region).
Any idea why and whether there is anything I could do to avoid that? Is the overall signal just to weak, or am I actually doing something wrong here?
Cheers,
Marc
