Haven't posted much lately as some minor equipment issues have cropped up along with some seriously crappy weather in this part of the world. Anyway this is a part of the Vela Supernova Remnant that surrounds the 4th magnitude star e Velorum. Although the area has some SII Idecided to limit myself to Ha and OIII for a HOO bi-colour image.
Total of 3 hours with 17x5mins of OIII and 19x5mins of Ha.
All processing done in Pixinsight. Pretty basic, just Photometric Colour Calibration,MLT, used STF stretch, a bit more NR with MMT and colour boost with LRGB combine.

Scope: Stellarvue SVR102T-IS with 0.7 reducer
Focusing: Feathertouch 3" with HSM30 motor
Camera: ZWO ASI1600MM Pro
Mount: Skywatcher EQ8
Filters: Astrodon 36mm Ha 5nm OIII 3nm
Guiding: ZWO ASI290MM and ZWO OAG with PHD2
Acquisition: SGP
Processing: Pixinsight

Nice one, Malcom! Your result here inspired me to stretch my recent image a bit more.

What gain were you using for your subs?

Also, are you able to let us know the full names of those pixinsight processes that you used? MLT and MMT are both new to me.
Thanks!

I was just using Unity gain. I usually just use that and if the subs look OK, I just leave it. MLT and MMT are Multiscale Linear Transform and Multiscale Median Transform. In this case I used them for noise reduction, MLT before stretching and just a touch of MMT after the stretch.
