Messier 8 Lagoon Nebula in SHO

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!

Comments Welcomed (Starless also attached as I think this nebula is beautiful without them!)
