About the Dumbbell Nebula

It is also known as the Apple Core Nebula.  It is a planetary nebula in the constellation of Vulpecula at a distance of about 1227 lightyears.

The Dumbbell Nebula was one of my earliest favorite because of the color especially when you look at it from the eyepiece of the telescope.

This image is captured using the Celestron 11″ SCT with the 0.63X flattener/reducer and with the ASI 1600MM camera with ZWO 8 positions filterwheel.  The filters I use are the Astronomik Ha, O3 and S2.

It took me over 2 weeks to capture and almost 2 weeks to process.  I thought that this will be an easy on because of the brightness but i was wrong.
