Freddie Posted September 16, 2017 Share Posted September 16, 2017 The subs for this (21 x 20mins) were captured over the last year. M82 was my "I'll just add a couple of extras" target whenever I was imaging with my Ha filter hence the subs being spread over a year. I think I've got to the point of diminishing returns though so it's time to stop. I do have a tendency to have lots of projects on the go but never decide to stop and produce a final image. I also have a reasonable number of L subs but have made the mistake of not getting any RGB and it's now getting quite close to the top of the tall hedge at the north end of the garden so I hope the weather is kind over the next week or so.

wimvb Posted September 16, 2017 Share Posted September 16, 2017 Thar's going to be a spectacular image, once you add the rgb. Great start. Link to comment Share on other sites More sharing options...

johnrt Posted September 16, 2017 Share Posted September 16, 2017 Looks great, will be worth the effort when you finally have all the data. Link to comment Share on other sites More sharing options...
Freddie Posted September 17, 2017 Author Share Posted September 17, 2017 Thanks for your comments guys. The weatherman isn't too hopeful I will be adding RGB to this any time soon !!!! Link to comment Share on other sites More sharing options...
adamphillips Posted September 17, 2017 Share Posted September 17, 2017 are you sure youre focused? Link to comment Share on other sites More sharing options...
Stu Posted September 17, 2017 Share Posted September 17, 2017 Looks great Freddie. I actually really like mono images because they are far more like the visual view That said, I'm sure the finished result will be wonderful. Link to comment Share on other sites More sharing options...

I don't think Freddie has given this the gung ho sharpening treatment but the stars look tight. Great stuff, I'd say. The jets reach right out but with a soft touch.

wimvb Posted September 17, 2017 Share Posted September 17, 2017 33 minutes ago, adamphillips said: are you sure youre focused? I too think he's focused () The scope (MN190) has a 1 m focal length, and the camera(Atik 460) 4.54 um pixels, giving a slight oversampling (0.9"/pixel). At this scale stars can look bloated in a processed image, even if they are well focused. Gentle star reduction in the final image will take care of this. Personally, I think that with RGB this is going to be a winner. As Olly remarked, the jets are soft but distinct. Link to comment Share on other sites More sharing options...
Freddie Posted September 17, 2017 Author Share Posted September 17, 2017 Thanks for your comments guys. Much appreciated. Yes, definately in focus, I don't think the detail in the jets would show up if not!! The processing has concentrated on the galaxy and the jets in particular to try and get them to be as clear as poss without over sharpening. The stars have therefore ended up a bit bigger than I probably could have made them but in the final image they will play no part as they will be replaced with RGB, assuming I ever capture any!! Obviously when I blend this into the R, I may end up processing it slightly differently. Link to comment Share on other sites More sharing options...
tomato Posted September 18, 2017 Share Posted September 18, 2017 A wonderful image, you can really see the structure in the jets. 12 months to capture 7 hrs of Ha data, that must be a UK location. Link to comment Share on other sites More sharing options...
Freddie Posted September 19, 2017 Author Share Posted September 19, 2017 Thanks "Tomato". I've started to work through my L subs now. Captured over 12 months but I just added a few subs here and there if I was imaging with my Ha filter so not as bad as it sounds. Conditions haven't been great though over the last year.

Space Cowboy Posted September 21, 2017 Share Posted September 21, 2017 Looking good Freddie! Plenty of detail in there. Link to comment Share on other sites More sharing options...
Dark Horizon Posted September 21, 2017 Share Posted September 21, 2017 Personally speaking, this is by far the best rendition of M82 in Ha that i've seen. IMO its jaw dropping! Congrats, Freddie. Link to comment Share on other sites More sharing options...
Freddie Posted September 22, 2017 Author Share Posted September 22, 2017 Thanks guys. "Dark Horizon" I do appreciate your comment, thanks but I know there are equally good and better images out there. I'm happy with what I have though given my location and kit.

swag72 Posted September 22, 2017 Share Posted September 22, 2017 That's looking very promising indeed..... I hope you get the chance to get the RGB I'm looking forward to seeing this completed. Link to comment Share on other sites More sharing options...
Freddie Posted September 23, 2017 Author Share Posted September 23, 2017 Thanks Sara. The RGB is looking doubtful for a while at least as the weather is not playing and M82 is getting lower every day. At least I have my L subs to process. Link to comment Share on other sites More sharing options...

Indeed. All of my data sets so far are a work in progress. I am going to change my strategy a little. Great Ha Freddie. Link to comment Share on other sites More sharing options...
