NGC1499 - California Nebula - HaRGB

[Buzzard75]

This is my first HaRGB image. Overall, I would say it turned out pretty good. I would like to have seen a bit more detail transferred from the Ha data to the red channel, but I haven't quite figured out all the nuances yet of combining narrowband with RGB data. It doesn't seem to be quite as straightforward as adding luminance. I extracted the R channel and combined it with the Ha data using a tutorial I found, but I couldn't quite get the result I was looking for. Oh well, more to learn I suppose. Data was captured over two days. I was chased off by clouds Friday night, but I was mostly doing some troubleshooting so didn't expect to get much data. Saturday night the transparency was excellent, but the seeing was pretty terrible.

Technical data:

ZWO ASI183MM Pro
Baader RGB filters (18x180s each)
ZWO Ha filter (19x180s)
William Optics Redcat
iOptron CEM40EC (unguided)
Captured using APT and processed in Pixinsight
32% moon
