Description

In December I had an accident with my Astro Tech AR6RC Ritchey Chretien scope. I had the scope attached to my mount with all of the imaging equipment attached to my scope. I balanced the mount and I was in the process of moving the scope on the mount. I wanted to check the tension on the worm gears because I had previously used a much lighter scope. As I was moving the scope with my hand controller it fell from my mount to my ceramic tile floor. The fall ruined my scope and completely destroyed my D5300 dslr camera. I've been working on repairing my Ritchey Cretien scope. I tried a lot of different things without success. Finally I decided to take the scope completely apart so I could see how everything was put together and see if anything was damaged. When I took the scope apart I could see exactly how the collimation worked on both the primary and the secondary mirrors which was helpful to me. I unbent/straightened what needed to be straightened. I then took different sized levels and I leveled the mirrors in the collimation brackets. I also leveled the baffling tubes. As I put everything back together I also checked that everything was level. I could not find a perfectly level place to put the scope together anywhere in my house except for my glass topped stove. So I put the scope back together on top of my stove. I then attached a cheshire eyepiece to my scope to check the collimation. The collimation was off so I adjusted the collimation. The first night that I could see a star or two I took the scope outside to check how the scope worked visually. It was obvious that the collimation was still off. I recollimated the scope 5 or 6 times over a period of 5 weeks. I would get frustrated fooling with it and then I would put it down for a while. Yesterday I decided to try and collimate the scope again. This time the collimation seemed tight. Last night was the first clear night I've had in a while so I decided to test the scope by imaging with it. For some reason last night my mount decided that it was going to give me problems. The mount stopped tracking and the majority of my images had trailed stars. I could not get the problem fixed. I worked for 30 minutes trying to resolve the problem but had no success. I only had 7 usable images to work with. Later in the night I decided to try my ED80 with the mount and had no problems at all. Anyway please enjoy my test image of NGC 891.
