Andromeda Galaxy OSC with H-Alpha Layer
I just reprocessed my November-Data in PixInsight. In November, I collected photons of M31 at two evenings. At one evening i collected RGB with my DSLR OSC and on the second i used my Duo-Narrowband-Filter, just to see if it works. Now i reprocessed Andromeda Galaxy OSC with H-Alpha Layer in PixInsight.
I process the data before in Affinity Photo, but without using the HA-data: Astrophoto: Andromeda Galaxy M31, Clear Skies 25+26 – astrography.eu
Meanwhile i use PixInsight for processing my data. Therefore i started to use my unprocessed data. It is really nice, that there are several really nice tutorials out there for literally everything in PixInsight.
A photo of a galaxie with a DSRL OSC with H-Alpha-Layer works pretty well, using the right software and the right tutorial.
The processing in Pixinsight is no witchcraft. But what i saw really fast, is that my 23 duo-narrowband-photos with 180s each at 7.5 is really not enough H-Alpha Data of M31. Yes, i collected photons, but the noise is something i had to handle while doing the processing. But since i had data, i wanted to use them and see whats possible.
The first steps in PixInsight were the WeightedBatchProcessing Script. I ran it two times. 1st time to get 3 Master-Files for the RGB-stack and the 2nd time with the data of the duo-narrowband-evening. This second stack holds the HA-Data in the Red-Channel.
I used the Tutorial of “Entering into Space”: (60) How to Imaging and Process M31 In Ha LRGB – YouTube
