tommy_h Posted September 28, 2012 Share Posted September 28, 2012 HelloHere is my attempt on M 57.I gathered the data during several nights in summer. Finally I got 12 hours of more or less good data.And it was the first time I tried the Astronomik 12nm Ha-clipfilter. But 8 hours of Ha-data don't bring very much improvement, maybe some details.10" Skywatcher Newton, EQ6, Canon 500D mod, ASA 2" Quattro Coma-CorrectorGuiding with Mgen and ASA OAGFull resolution cropped:More details: http://www.distant-l...-2012_06_16.htmThanks for lookingThomas Link to comment Share on other sites More sharing options...
michael.h.f.wilkinson Posted September 28, 2012 Share Posted September 28, 2012 Wonderfully detailed image, with really great depth to it. The outer envelope on M57 is nicely captured, and the distant galaxies come out really well. They lend much of the depth to the image.Stunning!

Cath Posted September 28, 2012 Share Posted September 28, 2012 I love it Thomas. As Michael says lovely detail Link to comment Share on other sites More sharing options...
Shibby Posted September 28, 2012 Share Posted September 28, 2012 Awesome Stunning detail and colour.My only question, why did you use only ISO 200 for the Ha data? Link to comment Share on other sites More sharing options...
RobH Posted September 28, 2012 Share Posted September 28, 2012 Excellent image. Great depth, masses of detail in the ring and good star colour.Do you have particularly dark skies?CheersRob Link to comment Share on other sites More sharing options...

Mark at Beaufort Posted September 28, 2012 Share Posted September 28, 2012 Great image and fantastic detail. Wonderful to see the central star.Mark Link to comment Share on other sites More sharing options...
rfdesigner Posted September 28, 2012 Share Posted September 28, 2012 Very nice shotHaving been playing with some of my own data on this one recently, it looks like you've got some very good guiding going on there, the detail in the nebula is excellent.Derek Link to comment Share on other sites More sharing options...
Moon monkey Posted September 28, 2012 Share Posted September 28, 2012 I think thats the best M57 ive seen .... very well done. Link to comment Share on other sites More sharing options...
Ganymede12 Posted September 28, 2012 Share Posted September 28, 2012 That is completely gob smacking! I didn't even realise there was a galaxy near M57! What aperture scope is needed to see the galaxy? Link to comment Share on other sites More sharing options...
NickK Posted September 28, 2012 Share Posted September 28, 2012 Now if I make a negative observation I'lm going to look stupid Very good detail, my only concern is it's a little flat - but like I said I'm never happy with anything!What processing did you do? Apps used? I think quite a few people would be interested. Did you dither/drizzle for example? Link to comment Share on other sites More sharing options...
Daniel-K Posted September 28, 2012 Share Posted September 28, 2012 awesome detail you have there i love that barred spiral next to m57 and you have a fair few fuzzy in there too! Link to comment Share on other sites More sharing options...
Stu Posted September 28, 2012 Share Posted September 28, 2012 That is an incredible image, very deep. I don't remember seeing that halo around M57 before and haven't seen that galaxy in images before either. It's not on my star charts either so no idea what it is!Stu Link to comment Share on other sites More sharing options...
tommy_h Posted September 28, 2012 Author Share Posted September 28, 2012 Thank you for your nice words.michael: The outer envelope on M57 is nicely captured, and the distant galaxies come out really well.That's what I wanted. But the the halo is very faint and with a DSLR it's impossible to get more details out of the halo, I think.Shibby: My only question, why did you use only ISO 200 for the Ha data?I have tried ISO 400 with 30min Subs for Ha, but the ring was burned out and have lost all details.Rob: Do you have particularly dark skies?I live in a little village, no large cities within a radius of 30 km.

I don't remember seeing that halo around M57 before and haven't seen that galaxy in images before either. It's not on my star charts either so no idea what it is!This is IC 1296, a mag 15 galaxy. I think 10" will will not be enough, but I don't know exactly.NickK: What processing did you do? Apps used? I think quite a few people would be interested. Did you dither/drizzle for example?Guiding and dithering was made with the Lacerta Mgen.Data reduction (stacking) with TheliStretching, curves, ... sharpening with FitsworkDynamicBackgroundExtraction in PixInsightGetting the details out of the ring with HDRMultiscaleTransform in PixInsight.Other processing in PhotoshopThomas Link to comment Share on other sites More sharing options...

Mr Q Posted September 29, 2012 Share Posted September 29, 2012 That is completely gob smacking! I didn't even realise there was a galaxy near M57! What aperture scope is needed to see the galaxy? I believe it's out of the range of your 8" scope even under excellent conditions. Someone else may chime in with the magnitude. Link to comment Share on other sites More sharing options...
Mr Q Posted September 29, 2012 Share Posted September 29, 2012 At mag. 14.3 and a surface brightness of 14, I doubt it's detectable in your scope even under excellent conditions. It's even out of range of my 10" newt since Ive' never seen it while viewing M57 under very good conditions. Link to comment Share on other sites More sharing options...

morimarty Posted October 2, 2012 Share Posted October 2, 2012 Some very nice detail in the ring and a lovely well processed starfield! Link to comment Share on other sites More sharing options...
Darth Takahashi Posted October 3, 2012 Share Posted October 3, 2012 I think you are doing your self a little injustice - the detail in the ring is fantastic, only a minor common but I'd reduce the background a little to increase the contrast but its a great image nevertheless.
