M27_Bi-Colour_7-9-2018

This was imaged in the west until it passed behind a tree, west is not the best direction from my location. This was taken back at the beginning of September but it’s taken until now to get the enthusiasm up to process it as I’ve imaged and processed this on 3 other occasions but this is the first time with this camera.

 

Object Description:-

M27 the Dumbbell Nebula is a Planetary Nebula and lies in the constellations of Vulpecula. Its distance is about 1,360 ly with a visible magnitude of 7.5 and a diameter of 6 arcmin so it quit a small but bright object and is easily seen in a small telescope. It is believed that this star went nova about 14,600 years ago.

 

Note:-

As there is a lot of detail to be had in the Oiii (like most planetary Nebula and Super Nova remnants) I combined it with the Ha to create the luminance Layer.
