Description

Now the cropped full frame version for you. Putting together all data from my CT 10 newtonian and some new data from my edge 11 HD at f 7. Because of it' brightness, a mix of several exposure times is neccessary for that iconic nebula of course. There are many different color versions shown here by several imagers and I find it challenging to choose the right ones. Here is my version of it now. Hope you like it.
