Fireworks Galaxy

I am starting to process a backlog of image data, and I have just posted my latest effort, which can be found at the bottom of my images page.  It is an image of NGC6946, the so-called Fireworks Galaxy.  I acquired the image data during July and August of this year, and used Pixinsight to process the data.

I think it is my best result so far.  As I have stated previously, astrophotography with a dobsonian telescope is difficult.  I limit myself to 10 second exposures due to the limitations of my drive system, the lack of guiding capability, and to minimize the effect of field rotation.  In this case I integrated 840 images, which certainly put pressure on my computer!
