Messier 8 Lagoon Nebula in SHO

[CoolhandJo]

I wanted to upload RGGB first but clouds and Moon prevented me from taking star data. So here is the SHO version. Its 10 hours of Ha Oii Duo band (L-Extreme) combined with 3 hours of Sii (SvBony). I took this in 4min subs on a Star Adventurer Pro2 with an ASI 522 MC Pro though and ED72 guided. I processed in Pixinsight and Photoshop. Bortle 5 on average. I cool the camera down to -10deg and fully calibrated the images including Drizzle, Dithering, Flats, Darks, Dark Flats, and Bias. I plan on finalizing my RGGB version with Dou band combined with Broadband (L-Pro) data once the moon goes away!

Thanks PK!

You've got some excellent data there Paul but your stars are muted so I reckon that must have happened during one of the processing steps. Worth a repro IMO.

You have a keen eye Marc. I had lots of issues with the stars. It was so windy gale force the poor tracker couldn't keep up! Had eggs for stars fir half the subs.

Ill add some rgb stars to my non sho version once the moon goes down.
