ollypenrice Posted September 8, 2013 Share Posted September 8, 2013 M74 in its natural habitat since this really won't stand up at full size. We lost an awful lot of luminance subs to focus drit, unfortunately. I was very busy on these nights and couldn't watch over this one (Yves' 14 inch ODK) as carefully as I should have done. Still, we have a picture of the little blighter;Bigger; http://ollypenrice.s.../M74 WEB-X3.jpgThis had 8x15 L and 7x15 per colour. I made a synthetic L from the colour data to help out the short luminance run.OllyEdit. Ouch, the background sky looks a mess on here. It was OK in Ps on my monitor. I'll have a look at that!

Jannis Posted September 8, 2013 Share Posted September 8, 2013 Not bad. Looks quite nice to me, and sky background looks OK also for me here at least. Link to comment Share on other sites More sharing options...
SnakeyJ Posted September 8, 2013 Share Posted September 8, 2013 Looks lovely Olly, when the weather allows I shall have another crack at this - could be on it all night if it wasnt for the pesky trees in the neighbours garden! Look forward to seeing you work that magic on this. Link to comment Share on other sites More sharing options...

RikM Posted September 8, 2013 Share Posted September 8, 2013 It'd be better without the gradient and dark halos My images often seem to get an extra stretch on uploading, so when you sort it, I would appreciate a few pointers Link to comment Share on other sites More sharing options...
ollypenrice Posted September 8, 2013 Author Share Posted September 8, 2013 We've decided to go for more data and try to do it properly. Odd about the gradient and dark halos because I can't see them in PS.Olly Link to comment Share on other sites More sharing options...
Moonshane Posted September 8, 2013 Share Posted September 8, 2013 very nice Olly. I saw (or rather detected) this for the first time last night from Stockport with my 12" dob. It was pretty tough though and really faint. looking forward to seeing it from somewhere darker. Link to comment Share on other sites More sharing options...

Sam Posted September 9, 2013 Share Posted September 9, 2013 That's fantastic, I really enjoy seeing images of M74, it's such a beautiful galaxy. Well done! Link to comment Share on other sites More sharing options...
RikM Posted September 9, 2013 Share Posted September 9, 2013 I think it's a monitor calibration thing. It looks perfect on my monitor at work but I know that normally displays a bit dark. Link to comment Share on other sites More sharing options...
ollypenrice Posted September 9, 2013 Author Share Posted September 9, 2013 It seems that the transition to JPEG has brought this up. The TIFF is clean.Olly Link to comment Share on other sites More sharing options...
Tom OD Posted September 9, 2013 Share Posted September 9, 2013 Glad you choose this object. I 've always wanted to see it from the ODK. Lovely job. If you're going for more data then looking forward to seeing it at full size. Link to comment Share on other sites More sharing options...
Knight of Clear Skies Posted September 9, 2013 Share Posted September 9, 2013 Very nice. Looking it up on Wikipedia, I see M74 has the lowest surface brightness of any Messier object. Link to comment Share on other sites More sharing options...
Mark72 Posted September 10, 2013 Share Posted September 10, 2013 Nice galaxy Olly, background looks a bit noisy indeed.You can also consider NGC1232 looks pretty much the same but may be brighter and not often imaged.Mark Link to comment Share on other sites More sharing options...
