Object Information                                            Imaging Details

The Triangulum Galaxy gets its name from its host constellation. In a very dark sky, the Sc spiral galaxy is visible to individuals with an extremely keen eye (that doesn't include me). For those who can see it, M33 is the most distant object observable with the naked eye at 2.78 million light-years (for comparison, the Andromeda Galaxy is 2.52 million light-years distant). M33 may be a large satellite galaxy to the much larger Andromeda Galaxy. The view of one of the galaxies from the other must be breathtaking.

M33 is easily viewed with any telescope (or even with binoculars; however, seeing detail such as the galaxy's arms requires a telescope of at least 12 inches. It's a splendid object to observe through a 20" obsession.

I imaged this object at ASLC's 'Upham' dark sky site (about 35 miles North of Las Cruces).
