NGC 3372 Carina Outer Regions

Captured NGC 3372 Carina Nebula for the second time this year , however instead of centre framing the object , I decided to focus on one of the outer arms of this gigantic nebula for a different aspect as the FOV on my rig only captures about 50% of the whole nebula.

Captured over 2 nights ( just over 6 hours integration)
Waning Moon 50% to 25%
Seeing conditions average
Bortle 8 City suburban skies
8”f5 Klaus Helmerich Carbon fibre Newtonian Reflector
Skywatcher EQ6-R pro mount
ZWO 2600MM cooled to -10C , Gain 100
ZWO 7x2” EFW
ZWO EAF
Antlia 3nm Filters
Ha 67x 2 min dithered subs
Oiii 62 x 2 min dithered subs
Sii 65 x 2 min dithered subs
Bias frames from library
Darks frames from Library
Flats Ha , Oiii and Sii
Analysed , Calibrated, Stacked and Aligned in ASTAP
Processed in Startools V1.8 via Compose
Used SV Deconvolution in Synthetic Mode

Created quite a few SHO versions using the Startools Matrix feature in the Colour module and then a slight tweak using DPP4.

Quite pleased with the results
The image was very clean with minimal noise to mitigate
The only anomaly was my Sii frames were not framed and aligned properly during capture plus I had some slight rotation as I don’t plate solve. Hence the only large star in the image has some splayed diffraction spikes as ASTAP couldn’t quite align the rotation perfectly.
Not a big deal

Had a lot of fun with this project
I’ll leave Carina now until next year to move onto other targets

Created 5 x SHO versions , 1 x HOO version and original Synthetic Luminance version


Comments welcome
Thanks for looking
