gnomus Posted April 6, 2017 Share Posted April 6, 2017 This is a large planetary nebula in Gemini. It was originally thought to be a supernova remnant, but is now classiied as an old planetary nebula. The data for this was captured over several nights at DSW on the Tak 106/QSI683 rig. Luminance: 13x900" bin 1x1 Red: 14x900" bin 1x1 Green: 15x900" bin 1x1 Blue: 13x900" bin 1x1 Ha 5nm: 15x1800" bin 1x1 There are faint dusty substances over the field. I'm still not sure how to pull these out without destroying the stars - so this represents a compromise position. Link to comment Share on other sites More sharing options...
toxic Posted April 6, 2017 Share Posted April 6, 2017 this is a beaut image and as for the faint stuff i think that adds to it the way it is just so natural top image Steve Link to comment Share on other sites More sharing options...

The Admiral Posted April 6, 2017 Share Posted April 6, 2017 Did you say "dusty substances"? Takes me back to an old Peter Cook and Dudley Moore sketch . I'll get my coat! Nice image by the way. Ian Link to comment Share on other sites More sharing options...
wimvb Posted April 6, 2017 Share Posted April 6, 2017 Great image. As you wrote, there's more lurking in the background. But that's the fun in AP; trying to get the last photon out of the data. Gerald Wechselberger has published a few video tutorials that may be relevant (PixInsight). But maybe that is old information. http://www.werbeagentur.org/oldwexi/PixInsight/PixInsight.html Thanks for sharing Link to comment Share on other sites More sharing options...

ollypenrice Posted April 6, 2017 Share Posted April 6, 2017 Very classy image with everything in place. Background, stars, DS object. I don't care what Pete says, that's no Dud.... Olly Link to comment Share on other sites More sharing options...
Allinthehead Posted April 6, 2017 Share Posted April 6, 2017 Very nice Steve. Would something like a screen mask invert in PS work on bringing out the feint stuff while protecting the stars? Richard. Link to comment Share on other sites More sharing options...

ollypenrice Posted April 6, 2017 Share Posted April 6, 2017 I don't think every image has to be a stunt. This makes a harmonious, convincing and natural whole. Sure, play around in search of the faintest stuff but don't feel obliged to torture your data. Olly Link to comment Share on other sites More sharing options...

wimvb Posted April 6, 2017 Share Posted April 6, 2017 Looking at the image on my computer, and not my mobile phone, I agree with Olly. There is some signal lurking in the background, especially weak Ha (maybe ERE?) to the left of the PN. But I think that in this case I would leave that to the imagination of the viewer, and not stretch the image further to squeeze out the last photon. There is a risk that noise will take over and that noise reduction will ruin the naturalistic effect of the image. Link to comment Share on other sites More sharing options...
gnomus Posted April 6, 2017 Author Share Posted April 6, 2017 Yes. I had been back and forth on this one, and had pretty much decided it was done. I was just being polite earlier... Link to comment Share on other sites More sharing options...

coatesg Posted April 7, 2017 Share Posted April 7, 2017 Lovely shot - very natural looking, lovely colours, and agree that it doesn't look pushed by trying to drag the background stuff out - the subtle texturing works really well with the framing.
