This is my rendition of the Dumbbell Nebula. Its about 7 hours through an L-Extreme Filter on ASI 533 MC Pro ED80. No reducer just a flattener. My OAG helped a lot and I was able to go 4 min sub frames no issue at all with guiding. Processed in Pixinsight. Seems to be a lot of faint nebulosity in the surrounding area that added to the star colours so I did not add RGB stars this time.
