Popular Post Astrobdlbug Posted March 29, 2022 Popular Post Share Posted March 29, 2022 Evening all, I am impressed with all the galaxies that are being posted, but during the recent run of clear(ish) nights I went my own way with an end of season nebula target. I have been imaging the Flame nebula in 3nm narrowband as it heads west and sinks into the grimy muck of the distribution warehouse light bubble that is my westward view. This LP is why in general I avoid image targets that are low and in the west. Which in hindsight begs the question why did I choose this imaging project last week..... Anyway, the positives, using 3nm Ha really cuts through the murk and I got a good 8.5hrs of Ha and solid 6hrs of Sii. I tried to image Oiii but despite pulling down 7hrs, there was nothing of use in the Oiii integration and the gradient was horrendous, even 3nm is no defence against bright LP and lots of high humidity atmosphere.. My processing solution was to include addtional data from my Auriga widefield from a few weeks ago and also last year. Overall there is contribution from approximately 25hrs of imaging based on ASI1600MM and 3nm Antlia filters through AT106EDT with 0.75x reducer and Samyang 135mm Lens. Due to the variety images and integrations used for this image I processed it mainly in PS as I can blend the different channels and images using layers and masks. I did use PI and the new Generalised Hyberbolic Stretch utility to stretch the new Ha and Sii integrations. I used a small amount of Topaz denoise, about 4 in the low light option and used the APF-R utility in Photoshop to sharpen the image under a mask. The full frame (with slight edge crop for stacking artifacts) and a crop of the Flame are below, thanks for looking Bryan 10 Quote Link to comment Share on other sites More sharing options...
