Stub Mandrel Posted December 27, 2020 Share Posted December 27, 2020 I share these images of examples of what can be done with less than perfect data. Yes, they need more data to be really good, but considering how many subs I lost to guiding glitches (the Sii on the soul is 27 out of 30 subs without guidiing - I just let the sigma kappa stacking deal with it, and it did better than expected.Horsehead SHO (Hubble):Horsehead HSO:Soul SHO: 9 Quote Link to comment Share on other sites More sharing options...

P Holdsworth Posted December 29, 2020 Share Posted December 29, 2020 Great images Neil. I think the way you've tamed the brightness of Alnitak is excellent. 1 Quote Link to comment Share on other sites More sharing options...

Stub Mandrel Posted December 31, 2020 Author Share Posted December 31, 2020 @p-holdsworthThanks, Part of the secret was 2 1/2 minute subs to make suer Alnitak wasn't over stretched. I then stretched those images solely in DSS(!) and just used Photoshop for the colour balancing and black point. If you take care it's s-shaped curves don't blow out the stars.I did have problems with diffraction patterns and a big halo around Alnitak in Sii and Oii but partly solved this by using the Ha as a luminance layer. I masked in the blue reflection nebulas, then decided this didn't improve the image and took them back out. 1 Quote Link to comment Share on other sites More sharing options...
