NGC 3372 Carina Eastern Outer Region

[Startrek (Martin)]

As the full moon was up over 3 relatively clear nights last week ( some high cloud in patches) I chose to image the eastern side of NGC 3372 Carina Nebula which has some interesting structures.

Location : South Coast NSW
Skies : Bortle 3
Conditions : Average to Poor seeing ( stars scintillating ) Transparency poor as well
Full Moon
Little or no wind
Heavy dew around 10pm on night 1 and night 2
Approximately 9 hours integration

Mount : Skywatcher EQ8-R Pro
Imaging Camera : ZWO 2600MM temp -10C , Gain 100
Coma Corrector : TS Optics GPU
Filter Wheel : ZWO 7 x 2"
Filters : Antlia 3nm Ha , Oiii and Sii
Guide Scope : Orion 60mm with helical focuser
Guide Camera : ZWO 290MM
60 x 3min subs Ha
55 x 3 min subs Oiii
57 x 3 min subs Sii
Darks from Library
Flat darks for Ha , Oiii and Sii ( compared image calibrating Flats with Bias frames and no obvious difference
Flats Ha, Oiii , Sii
Tracking and Goto : Eqmod and Stellarium
Aquisition : APT
Guiding : PHD2 ( 0.60 to 0.70 arc sec total rms avg which is due to conditions)
Analysed , Calibrated and Stacked in ASTAP
Processed in Startools V1.8 ( Data Sets loaded into Compose , Color SHO: HST , HOO and SHO OHS preset with colour tweaks )

Very nice Martin!
I too prefer the first image with the more traditional palette.

[Ryderscope (Rodney)]

Nice work Martin. Good to see you getting amongst it with a busy moon about. I go with the first image as my preference as well

Great shot Martin and another interesting framing. The dew and seeing has been quite frustrating up in Sydney as well recently and even the last couple of nights trying to shoot in ‘clear’ skies and when you look outside it’s just a haze. Makes the final result all the more rewarding when you can finally pull it all together! Well done!

Nice pic, I really like it. There's nothing like finding a commonly imaged target, and then using a longer focal length to highlight an interesting part. It gives very really nice different perspective. Of the three, I also prefer the standard SHO version.

Thanks Gents,
Appreciate all the comments
Carina is such a beautiful nebula when you get in nice and close ( but not too close ) The 1250mm focal length on my 10” is ideal for these sort of outer region images.
Also very impressed with the 2600MM and the Antlia 3nm filters under a full moon too, they are damn good filters but not at a ridiculous price.
It seems like every time I want to image galaxies from my Dome under dark skies the bloody weather sets in
You take what you can get when skies are clear regardless of the Moon

Cheers
