NGC 3372 Carina Nebula and Antlia ALPT ( Full Moon )

Post by Startrek »

The Easter holiday weekend provided 3 clear stable moon filled nights
Moon Full to 95% waning
Bortle 8 Skies
Captured about 12 hours over 3 nights on NGC 3372 Carina Nebula using my 6” f6 GSO Newt , EQ6-R pro mount and 2600MC camera with Antlier ALPT 5nm OSC Dualband filter

Bin 65%
Image size 4005 x 2620
252 x 3 min dithered guided subs
3 x 40 Flats
1 x 100 Bias

Stacked in DSS

Processed in Startools V1.8 ( via Compose OSC/DSLR Bi Color )
Final noise reduction was only 2 pixels but could have skipped noise reduction as final image was so clean

SV Decon worked beautifully again, this time pushed a bit harder with 15 x iterations ( very minor ringing or image grain )

Synthetic Luminance version
Some SHO versions using the Color Matrix

Some cropped regions of Carina to explore a bit deeper

I have nothing to say but praise. Lovely understated processing (a very valid choice), that holds up well even when zoomed in. Excellent work! :bow-yellow:

Thanks Ivo,
Appreciate the kind comment
Probably one of the best quality data sets I’ve had to work with from my City suburban location
It was a joy to process in Startools ( very simple but effective)

Impressive. Most impressive. :D

Oh, just one of the more spectacular bicolors I think I've seen. :bow-yellow:

For this, I think I like the orange/pale white-blue version best.

It has a very good overall look to it, and I'm sure well-chosen framing was involved there too. From the astrobin description, pretty minimal processing. Nice use of AutoDev. Contrast at 30 is, I believe very light on the locality and thus does not dig deeply. And makes sense as you then refrained from HDR as well, and no sharpening. Just SVD really! :thumbsup:

For this target and your great acquisition, it just seems to work - a lot of detail is there even without additional contrast and HDR enhancement, and maintaining the intensity of the bright areas sets off the darker and shadow regions perfectly.

Mike,
Thanks for your generous comments
When I performed my initial AutoDev stretch I new this data set was something special as it was virtually noise free , just some moon glare gradient that Wipe took care of using NB preset
I decided to go light on processing ( excluding many modules including HDR and Sharp) which was the correct decision
Integration time as well as good sky conditions were the key , I’d never amassed nearly 13 hours on one object before. Mother Nature was kind to me providing 3 great consecutive nights
Thanks again
