HA processing was a breeze with only 6 hours of data, OIII with 7.5 was a different story. I was getting some weird gradients, not entirely sure from what, I was imaging well away from any light dome, no moon. Maybe bad flats. Anyway, with some careful masking I was able to fix it, but I was surprised to see how subtle the OIII was compared to HA.
I would love to do a SHO combination on the Heart or an HaLRGB, but the weather has been horrible and I need to get on with the winter targets. The combination process was new to me, but not terribly tricky I don't think, but plenty of room to improve. I do think the image took an overall hit in contrast after combination when comparing it to my HA integration. I would love to hear opinions and tips on how to keep the contrast through the combination process.
Acquisition details and high res on astrobin, I don't even bother with the lousy jpeg on here anymore,C&C welcomed, and
thanks for looking!
