Last evening, my brother Anthony & I observed several objects with our 5" computerized MAK. We were able to observe about six galaxies including M51. We were able to see its spiral affect coming out of its core. We also observed two planetary neubulas which looked blue. The two red stars, Hind's Crimson Star & The Garnet Star looked stunningly red. The grand finally was we were able to split Sirius & Sirius B. Right now, both stars are at their farthest separation so now is the time to look at this double.

This is the messier object which everyone neglects to see (even myself). I just made up my mind to update my messier observations and saw it and it was worth seeing. A good double star.

M 40 is a faint double star in Ursa Major, which found its way into Charles Messier's famous catalog by mistake. It is easily split into components at 36x, both stars are slightly red.

At last! After many failed attempts to observe M40 with 7x35 binoculars during the summer and fall, my new 10x50's finally brought it into view. It popped in and out, but I could hold it for many seconds at a time. M40 is listed as mag. 9, which was near the limit of what I could see this night. M40 is the 63rd Messier object I've observed with binoculars since June.
