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!

An Overdue Post

It has been nearly three years since my last post.  During this time Zephyr Ridge Observatory has remained in operation, and I have continued my efforts in visual observing.  I will write more about this in a future post.  The purpose of this post is to call attention to a new Images page for this blog (see link at the top, or just click here.)

Early this year I acquired a new Mallincam Universe color CCD camera and I have been trying to make use of it.  I had some initial problems which turned out to be computer-related, but now I think the system is working.  So, I have entered the difficult realm of astrophotography, and am doing so with a telescope that is designed for visual astronomy.  My Obsession telescope does have a drive system, but an altazimuth mounted dobsonian limits me to very short exposures due to field rotation and lack of a system for guiding.  On the plus side, I enjoy excellent optics and a 20″ diameter mirror.

I have uploaded two images, and am currently processing some others.  I will continue to add to the gallery as time goes on.
