draco triplet with asi1600mm and newtonian 200/1000

[tonioche]

hi all, here's a little image from this weekend, taken with my newly acquired 200/1000 newtonian.

i shot it with an asi1600mm and zwo lrgb filters. i used individual 180 second exposures and stacked them in DSS, then used siril to assemble the rgb image then processed it in photoshop.

L: 40x180sec

RGB:3x18x180sec

mount: EQ6R guided with zwo OAG and asi290mm mini

i like this triplet with lots of distant galaxies in the background.

clear skies

Nice one...can see around 30 fuzzies there,and thats on my small tablet.

[SIDO]

Excellent, lots to see there. The newly aquired newt is rocking it.

[Sunshine]

Is that ever a wonderful image, immaculately tracked, a lot of fun to search for fuzzies.

[wimvb]

That's an excellent image. Well caught and well processed. You must be pleased with your new scope.

[Demonperformer]

Excellent shot of a nice grouping.

[Yawning Angel]

Beautiful image with lovely composition. Especially like the careful alignment of the diffraction spikes

[gorann]

Great image with a lot of fuzzies in addition to the major galaxies! What Newtonean is it?

Maybe the sky is a bit too bright for my taste. It is around 35 - 40 (PS units), while most seem to prefer it to be around 20 (I think Olly says it should be 23/23/23). There is no apparent structure in it so I do not think it is integrated flux nebulosity (IFN).

Very nice image.

What coma corrector are you using?

What I find so remarkable about this image, is that even with a relatively short integration time, you managed to capture a hint of the shell structure in the elliptical member of this group, ngc 5982.

Very nice image. Whenever I see a quality image it makes me want to view the area with my 12". I am hopeful for NGC 5982 and 5985 but I think that the edge on NGC 5981 will be beyond my reach.

Really pleased you posted this image.

i'll agree with you on that one. i didn't measure it to be honest, just did it visually and it really depends on the screen you're viewing it on.

it's the skywatcher 200 f5

Yes, we cannot really trust what we see on the screen and the light level in your room also plays a big role so it is a good idea to keep an eye on the values in the histogram. In your case it is easily fixed with a tweak of the curves - much worse if one ends up with a too dark sky and clipped dark data in the image. I usually keep the sky as bright as yours until the very end to make sure I do not clip it during processing.

[tonioche]

here's a version with a little bit darker background. 😉

[Mark at Beaufort]

That is very nice and I do prefer this version.

Since your original post I noticed that I observed NGC5982 in 2011 and 2017 but no record of the other two. I have also noted that Sue French in her book - Deep Sky Wonders  she stated that all three were viewed in her 10" Newt.

Look forward to darker skies.
