It also contains some amazing nebulae and other deep space objects, e.g., NGC 604 is a massive H II region-that's the bright pinkish blob, the size of a large star, at the lower left side of the galactic spiral. It's the third largest galaxy in our local group, and appears to be bound up in Andromeda's gravitational pull. Triangulum Galaxy, M33, is a nearby spiral galaxy-around 3 million lightyears away, with as many as 40 billion stars. (WilliamOptics GT81, ZWO ASI071MC: 60 x 60 second and 60 x 120 second exposures, unity gain). Located in the constellation Taurus, the Pleiades is a nearby open star cluster mostly made up of a batch of relatively young B-type stars amid (or behind) a reflection nebula that appears to surround and fill the space between the stars with veil-like sheets and threads. It's one of the most identifiable objects in the night sky, but it's more than just a loose group of stars. The Pleiades, M45, also known as "The Seven Sisters" and in Japanese as Subaru (昴). (ZWO ASI071MC running at -10C, William Optics GT81 + WO Flat 6A II f/4.7, CEM25P EQ mount, Orion OAG + ZWO ASI120MM-S guide cam, Stellarmate OS (INDI/KStars/Ekos) running on Raspberry Pi 3b+). I had several hours of clear skies, still relatively dark before the moon rose, and I set up the William Optics GT81 and ZWO ASI071MC color camera to take a bunch of subs of M33 and M45-Triangulum Galaxy and the Pleiades, two of my favorite targets this time of year-but this is my first time shooting these with the ZWO ASI071MC cooled color camera, and the resulting images show how amazing the ZWO is. And here for my 2015 - 2016 Astro Journal Posts Email me here: or see the links below to my other sites. We live in a town with very few street lights, and the sky glow we get is usually low on the horizon, Hampton to the south, and Portsmouth to the north. Unless specified, everything you see in my Journal is from my equipment in my backyard, which is about a 4 on the Bortle Scale (SQM: 20.62 mag/arcsec)-on a clear night I can still see M33. I'm always building and devising better ways to automate and remotely operate my gear, and I post related stuff on my Astro Automation page. I post finished and processing-in-progress shots here ( home page), and my equipment setup information (pics of my scopes and lenses, imaging train layouts with focal distances, focus wheel filter order, lens and scope backfocus, etc.) on the Equipment page. I'm an amateur astronomer and astrophotographer in coastal New Hampshire, working in narrowband and RGB color, focusing mostly on deep space objects-nebulae and galaxies, with some intermittent planetary and solar photography (because our sun's the nearest star and the planets and our moon are simply beautiful).
