finally a break in the clouds - ngc 2683

Recommended Posts

After what seems like an eternity, last friday the clouds finally parted for a few hours and I was able to do some imaging.
NGC 2683 is a type SAb galaxy in the constellation Lynx. It is located approximately 32 Mly from the Milky way.
The galaxy is seen edge on, and covers only 9.2' x 2.2' of the night sky.

Imaging details:

  • SW 150PDS on a SW AZ-EQ6 GT
  • ASI 174MM-Cool + ASI EFW and ZWO LRGB filters, at -25 C, gain 20
  • Guiding: ST80 + ASI 120M-S + PHD2

All this controlled by INDI/Ekos on 2 Rock64 sbc's

  • L: 27 x 120 s
  • RGB: 12 x 240 s each

Total integration time: 3.3 hrs

Processing: PixInsight

Very nice indeed,makes a nice change to mingle with the Nebulae.

Yes nice capture.

Thanks, Mick.

It took a while to get my setup running again, after almost 3 months of collecting dust. If the weather plays nice, I plan to at least triple the integration time.

Yes, good final catch Wim!

I just wonder a bit about the colour. Maybe tweak it a bit towards more "galaxy" blue-yellow.

Thanks, Göran.

Believe it or not, but I already did that. This target needs more data to do it justice. Hopefully I will be able to add to it.

Very nice Wim!

Maybe tripling that integration time will give better definition and brighten the overall image.

Thanks, Firas.

Yes, more integration time will allow me to stretch the data more and give better definition. This galaxy has a bright core, but also a very weak outer ring (the galaxy is magnitude 10.6). The outer ring needs more data. 

I'm just lucky I was able to collect this data at all. The weather forecast only had a gap for about 3 hours, but it stayed clear for most of the night. Unfortunately, too much of that time went into setting up. We had a severe storm recently, and for safety reasons I had moved all my gear, except the mount, out of my roll-away-shed. It took a while to get everything in order again.

@gorann: I mixed a small amount of the red channel into the green, in order to get a better colour balance in the core, but clearly not enough. This image will get a reprocess when I have more data.

Better?

Yeah that looks better.

Good detail in those inner dustlanes already.

Thanks. Despite the small amount of data, the luminance responded well to deconvolution. This and "a pinch" of HDR compression did the trick.

Yes, looks as good as it can get. Good luck tonight!

Thanks, Mark. Clear Outside predicts clear nights, but unfortunately also a full moon. Doubtful if I can add more data soon.
