M76 The Little Dumbbell Nebula - a photo on Flickriver

            Like the more prominent Dumbbell and Ring Nebulae, M76 is the remnant of a collapsed star some 2500 light years distant.  It is the faintest of the Messier objects.  This image is an LRGB image from a mono camera on my guided Questar telescope and might be improved with narrowband filtering.

Tech Stuff:  QHY163 mono camera mounted on Questar 3.5" scope at native 1500mm focal length (f17).  Guided by ZWO 120MC with 100mm lens using PHD; PixInsight used to combine and process several SharpCap livestacks of 8-15 second exposures for each layer; total exposures by filter are as follows:  Astronomik CLS as L layer 68 minutes; R 42 minutes; G 32 minutes; B 35 minutes.  Imaged from my yard 10 miles north of New York City.
