New Image: NGC2775 from the Ashes

#1

Post by sdbodin »


Binned this one when shot on April Fool's Day. Horrible seeing, windy and gusty, plus terrible gradients (see below) both luminosity and color, probably shot too early and twilight interfered.

But, to the rescue!! The new version of GraXpert . Haven't used this before so poured the data in and let it grind away. It worked and on the default setting at that, I don't know enough about this program to fiddle with the settings yet.

Had the galaxy offset to the bottom to get those two tiny blue motes in on the top, NGC 2777 and the string bean LEDA 213577. NGC 2775 is a SA type with a flocculent set of rings, just suggested here, Hubble pic is quite good at showing the feature. Anyway this data set was in the dust bin, and got salvaged by new software, amazing what computers can do.

Exposure data; Meade 16 LX200 at 2500mm efl, f6.2, Atik460ex mono, 15/2 min lum. 5/2min ea. RGB, all 2x2 binned for 0/7"/pixel. Posted final image near full frame and full scale.

Clear skies,
Steve
Scopes; Meade 16 LX200, AT80LE, plus bunch just sitting around gathering dust
Cameras; Atik 460ex mono, Zwo ASI1600MC-cool, QHY5L-II color and mono

Steve, I don't know a lot about digital processing, but that looks amazing to me!

It is pretty wild what the new software is capable of recovering.
I think about all the data I trashed a few years back that probably could have survived with a pass through some of these newer programs.

Nice capture Steve! Great processing to pull it out of those gradients.
