cwit1 Posted April 11, 2016 Share Posted April 11, 2016 Hi all, Finally had enough clear sky (at the right time) to get some imaging done. I got some 38 lights of M101 the other night along with darks, flats and bias. I captured with Backyard EOS and processed them with Nebulosity and PS6 and Lightroom ( for the noise reduction). Still struggling with the processing though! but overall quite pleased. What do you think? Chris. Link to comment Share on other sites More sharing options...

wavydavy Posted April 11, 2016 Share Posted April 11, 2016 Its a great image pulling in loads more background galaxys as well............ tried running astrometry through it but nothing shows.........will try again. Looks like a big PN. Link to comment Share on other sites More sharing options...
Knight of Clear Skies Posted April 11, 2016 Share Posted April 11, 2016 Nice image. The object n the right is a companion galaxy disrupted by M101, NGC 5474 I think. Some of the stars and faint galaxies look a little green to me, you may want to check your colour balance or use something like Hasta La Vista Green (plugin).

cwit1 Posted April 11, 2016 Author Share Posted April 11, 2016 Here's another with Hasta La Vista Green ran on it, much better I agree, Thanks !! Chris Link to comment Share on other sites More sharing options...

StuartJPP Posted April 13, 2016 Share Posted April 13, 2016 Yep, 2nd one is much better. Link to comment Share on other sites More sharing options...
Pompey Monkey Posted April 13, 2016 Share Posted April 13, 2016 What do I think? I think it's very good: Not over processed and the black point is not clipped, both common mistakes, especially with limited data. Link to comment Share on other sites More sharing options...

Could anyone explain what that means? In simple terms if possible. I tried google but ended up on hedge trimmers! TIA. Link to comment Share on other sites More sharing options...

In simple terms if possible. I tried google but ended up on hedge trimmers! TIA. Sure. In attempts to make the background sky look "black" (which it isn't) some people slide the left hand histogram control of the image processing (the "black point") software to the right... This has the effect of making every part of the image below a certain brightness appear as the same uniform black.... Unfortunately, much of the interesting (and hard worked for) parts of the image of astronomical objects lie in just this region of "not quite black". Making all of this subtle information the same colour is really defeating the point of astro imaging Link to comment Share on other sites More sharing options...
alacant Posted April 14, 2016 Share Posted April 14, 2016 Yeah, got it. Thanks. I was one of those who thought that the sky had to be black otherwise you'd failed and it was a bad image. My (false sense of security) trick was to come out of StarTools and bum up the contrast in GIMP. How right you are: how much faint detail is lost. I just took a step forward:) Link to comment Share on other sites More sharing options...
ollypenrice Posted April 14, 2016 Share Posted April 14, 2016 With the green sorted you have a superb image and need to be banned for life from the beginners' bit of the imaging forum! Flat, neutral background sky, small, accurately coloured stars, structured main galaxy, interesting faint fuzzies abounding, good tracking. An expert performance!

cwit1 Posted April 15, 2016 Author Share Posted April 15, 2016 Many thanks for the kind comments gents, very encouraging ? Olly an expert performance?....not if you'd seen and heard me performing.....not very polished I'm afraid..? Chris Link to comment Share on other sites More sharing options...
Mercona Posted April 16, 2016 Share Posted April 16, 2016 Awesome photo. I just recently am getting into astrophotography. It's very difficult to get a good picture to say the least. I've been using registax6 but it seems to crash 90% of the time. Link to comment Share on other sites More sharing options...
