M33 Triangulum Galaxy
A galactic neighbor 3 million light years away. This version using my TV-85 telescope with 4 second unguided exposures is comparable to my prior efforts using more conventional imaging techniques. The short exposure/livestacking approach enables decent quality imaging using portable mounts.
Tech Stuff: Televue 85 scope/Borg 1.08X flattener/ZWO ASI1600MC/IDAS LPS-D2 filter/SkyWatcher Star Adventurer mount; 48 minutes of 4 second exposures acquired using SharpCap in 8 livestacks with dark subtraction. RGB image combined with mono image here www.flickr.com/photos/124244349@N07/50313524907/in/photos... (same scope, different camera; also 4 second unguided exposures). Processed in PixInsight and finished in ACDSee. From my yard in Westchester County, NY. SQM-L readiings 18.4-18.8 (Bortle 7)
