Description

M76 is a very teeny, tiny Messier object known as the Little Dumbbell. 

It occupies an area of 2.7 by 1.8 arc minutes of apparent sky, which corresponds to a spatial diameter of only 1.23 light years. The nebula's size and faintness makes it one of the most difficult Messier objects to observe.

With my Esprit 120mm at 840 mm focal length it is incredibly small in the FOV.

The hover shows the original image.

I drizzled X1 in Pixinsight which I think helped with the resolution.

For those interested in making the pixel size the same for the wide FOV and the Zoom I used Irfanview. I never figured out how to use PixInsight to make both images the same EXACT size.
