I've been having to wait until nearly 10pm for my actual target to rise for my first 'REAL' image from this new scope, so rather than just sitting around the the proverbial finger in ones bum, I figured, use that time and get some data on something with a high surface brightness...

Well despite only being 2.5hrs of total integration, this, I like.

M20 in (Ha+R)GB

22x180s Ha
30x180s OSC
60x Darks

OSC data was split into its component channels and I removed the stars from the Red and Ha data.
I discarded the Ha stars, then the Ha starless was then added to R starless.
Next, I re-added the stars to the now Ha+R data, then recombined Ha+R, G and B.

Equipment:
Askar 120 APO + 1x Field flattener
Player One Artemis-C Pro (IMX294)
Player One Filter Drawer
Player One OAG + Sedna M (IMX178)
Player One UV/IR Cut
Askar D1 6nm Ha/OIII (OIII data discarded... too much moonglow)
Emcan Astro EM31 Pro harmonic mount.

Alex,
A lovely Trifid with Ha accent and nicely processed as well. I imaged the same target back in August with Ha and the field around this object has loads of Hydrogen to expose, in hindsight I should doubled my capture of Ha.
Well done !!
