I felt the time has come to take a new image of the Cocoon Nebula. So here it is with the Moravian G2-8300 at the 12″ f/4 Newtonian with LRGBHa = 430:100:100:100:290 minutes which gives a total exposure time of 17 hours. Subexposures were 10 minutes. I tried Hb too with 30 minutes subexposures but I did not use them because they did not really change the image.
Under the menu New Images you will find the zoomify version, so you can watch all the details of this beautiful nebula.
