M27 The Dumbell Nebula

I never get bored of the Dumbell Nebula. I love the way it just floats there in the cosmic abyss. It was the first planetary Nebula discovered by Charles Messier in 1764 so not a lot has changed in the last 250 years or so. In 1970, its velocity was estimated at 31 km per second giving an expansion of about  2.3" per century. 

My equipment is still quite new to me so getting used to things more each session. However guiding tonight was erratic at just over 1' RMS.  I am hoping to start on the new observatory soon still though deciding on the design.
