	Comments: This was the first picture with successfully guiding the 925 on the CGEM mount. Temperature was about 60F. The shots were processed in Images Plus, dark frame applied, and finished in Photoshop. The photo replaced the older one shot with an 8" LX200 that suffered from focus issues. The field flatness of the 925 is pretty incredible. The Dumbbell Nebula was the first planetary nebula ever discovered. Charles Messier discovered this new class of objects on July 12, 1764. We view M27 approximately from its equatorial plane. A view from near one pole would probably show it as a ring and perhaps look like M57. The central star of M27 is quite bright at magnitude 13.5 and an extremely hot blueish subdwarf at about 85,000K.
