Image Description and Details : M45 (Pleiades) in HOORGB, 98 hours taken over the course of 19 nights.I've wanted to take this picture for a couple of years, but whenever I could get to my dark sky site, it was cloudy. The stars finally aligned (literally) and I was able to get a good amount of RGB data from my dark sky site this winter.During my research for taking this photo, I noticed that some images had small amount of faint Hydrogen Alpha immediately around M45, so I figured I'd pile on some HA data for my wide field image and see if any more hydrogen would present itself...I was pleasantly surprised to find some wispy streams of hydrogen that I'd never seen before, right outside of the star cluster.The RGB data was taken from my dark sky site in Bone Cave, TN. The narrowband data was taken from my backyard in Nashville, TN.Imaging details:Imaging Telescope: TPO UltraWide 180 f/4.5 Imaging Camera: ZWO ASI2600MC Pro Mount: Sky-Watcher EQ6-R Pro Filters:Baader Fringe Killer 2"Optolong L-eXtreme 2" Accessories: ZWO ASIAIR Plus, ZWO EAFSoftware: Adobe Photoshop, Aries Productions Astro Pixel Processor (APP), Pleiades Astrophoto PixInsightGuiding Telescope: ZWO 30mm Mini Guider ScopeGuiding Camera: ZWO ASI290MM Mini Dates:Nov. 18, 2022, Nov. 19, 2022, Nov. 20, 2022, Nov. 21, 2022, Nov. 22, 2022, Nov. 23, 2022, Nov. 28, 2022, Nov. 30, 2022, Dec. 12, 2022, Dec. 15, 2022, Dec. 16, 2022, Dec. 17, 2022, Dec. 18, 2022, Dec. 19, 2022, Dec. 20, 2022, Dec. 23, 2022, Dec. 24, 2022, Dec. 25, 2022, Dec. 27, 2022, Jan. 1, 2023Frames:Baader Fringe Killer 2": 538×240″ (35h 52′) (gain: 100.00) -10°COptolong L-eXtreme 2": 467×480″ (62h 16′) (gain: 100.00) -10°CTotal Integration: 98h 8′Darks: 60Flats: 60Flat darks: 100

Image Description and Details :

The California Nebula. 110 hours of integration, imaged for 29 nights over the course of 2 months.It seems rare that I see images of the California Nebula with more than 40-50 hours, so I wanted to pile on a lot of data and see what details I could bring out.Imaging details:Imaging Telescope: OPT Telescopes TPO UltraWide 180 f/4.5Imaging Camera: ZWO Astronomy Cameras ASI2600MC ProMount: Sky-Watcher USA EQ6-R ProFilters:Baader Planetarium Fringe Killer 2"Optolong Astronomy Filter L-eXtreme 2"Accessories: ZWO ASIAIR Plus, ZWO EAFBaader Fringe Killer 2": 350×5″ (29′ 10″)Optolong L-eXtreme 2": 818×480″ (109h, 4min)

Image Description and Details : The Horn of Monoceros: 102 hours of exposure over 29 nights.

There is so much nebulosity in this region that I just couldn’t stop piling on data to see what would be revealed.

I hope you enjoy this image as much as I enjoyed creating it!
