Great Orion Neb (again) - ZWO plus F6.3 Reducer

So.. this is a final render of an imaging session from the other night using a ZWO ASI224MC + a newly acquired F6.3 Focal Reducer on my 8"SCT.

Still learning my way round this camera & experimenting with exposure times, gain settings, etc... Final image came out in mono... which kinda surprised me a little but, that might be because of the setting I had in ASICAP (8 bit, FITS format. Still playing & figuring out what Startools does if I play with the settings too...

Anyways... 148 images, Exp: 739Ms, Gain: 479, stacked in DSS, rendered in Star Tools & very slight tweak in Affinity Photo.. No darks (I forgot), no flats (I'm working up to that) & no bias (coz I have no idea what they are or how to do them yet)

I have some other data to process using an F3.3 Focal Reducer plus some using a UHC Filter.. will post results when done..

Please feel free to comment, provide advice, etc... bit disappointed that they are in mono but, then again, more representative of what you see at the eyepiece I suppose...

Core is a bit blown out, I think the stars are a little less bloated than in my earlier attempts with the DSLR... (couldn't use that the other night, it was hitting on the base of my fork mount as M42 was close to zenith)

Thanks for looking...
