Triangulum Galaxy M33 (NGC 598)


This image is a collection of amateur data all captured from my backyard observatory in Western Michigan. Exposed in LRGB and H-Alpha using QHY23 and QHY9 Monochrome CCD's with TMB130, TMB92 refractors and a Takahashi E180 Astrograph.

Total Integration Time 25 hours

NGC604 (One Of The largest HII regions within our local group of galaxies) and many other HII regions can be seen at high resolution in this annotated view

Earlier data can also be seen here

The Triangulum Galaxy is the third largest galaxy within the Local group, behind Andromeda and our own Milky Way. Found in its namesake constellation of Triangulum, this galaxy bears the distinction of the most distant object which can be seen with the naked eye.

The Triangulum Galaxy is a wonderful example of a classic spiral galaxy. It has enjoyed a rather queiescent life, having evolved without any major tidal interactions with other galaxies and its structure is very uniform as a result.

In 2007 astronomers using the Chandra X-ray Observatory, in orbit around Earth, detected the largest stellar-mass black hole ever found within M33. The 16 solar-mass black hole has an obital stellar companion, and from our vantage point, the black hole eclipses its binary companion, blocking its view, every 3.5 days.

M33 is also an important object to astronomers because it is the ultimate gauge for the darkness of a location. It takes just a tiny bit of light pollution to eliminate this object from view.
