First things first, apologies for posting this one out of season. A combination of no astro dark, crappy weather, and being busy at work has meant that there's no imaging getting done at all these days. So, i've had to turn to old data to re-process, and this data set was an obvious candidate as i was never happy with how it came out originally. And looking back on it now with fresh eyes, boy did it need it!
Nikon D5300, SW 80ED, HEQ5-Pro.
3 x 1200s, 2 x 1380s, and 4 x 1500s of Ha
9 x 1200s of Oiii.
11 x 480s with an IDAS-D1, for RGB stars only
7 Hrs 54 Mins in Total.
Stacked in APP and processed in PS.
Combined as SHO (using a 70/30 blend of Ha/Oiii for the Sii).
The main differences this time were, using Starnet++ to create the starless versions, using more Ha in the synthesized Sii (70% instead of 50% last time), but mostly the improvement has come from toning down the stretch a lot (ok, a heck of a lot!) before making the colour map for the tone-mapping. From then on it was immediately apparent that i'd made a massive boo-boo first time round 🙈
I've included a 1080p rotated crop too, as i quite liked the framing.
Feels like ages since i last did any NB imaging. I almost forgot how much i enjoy it! 🙂
And rather embarrassingly, here's the original. Try not to laugh too hard! 😂 😂 😂
Finally completed my SHO version. There is some purple in the image I cannot figure out how to get rid of and I'm sick of playing with it. Hints and tips on how to get rid of it welcome, I'm using PixInsight.

Thanks for looking!
