2024-10-23: Triangulum Galaxy

The Triangulum Galaxy is a spiral galaxy 2.73 million light-years from Earth in the constellation Triangulum. It is the third-largest member of the Local Group of galaxies, behind the Andromeda Galaxy and the Milky Way.

Viewing Location – Crystal Lake Recreational Area

I was tired and tried to squeeze this in. Unfortunately the trees were in the way so I only got 20 minutes of decent viewing time. I got a slightly better image with 5 times less observation time than I did in my backyard (bortle 7).

  • Lat/Lon: 34.32588, -117.83712
  • Sky Magnitude: 20.65 magnitudes/square arcseconds
  • Sky Luminance: 0.594 mcd/m2
  • Bortle-scale: 4 (rural/suburban transition)… which isn’t bad for being only 1.25 hrs drive from my house.

Observation

  • Catalog Designation: M33/NGC 598
  • Celestial Coordinates: RA 01h 33m 50.02s | Dec +30° 39′ 36.7″
