As promised, I'm going to post the first image using the 6 inch dob and the Ponset platform. There are some bugs in it, for one thing, the motor turns too fast and blurs the image if I slow it down so the image stays put, so I'll have to use a different stepper with a worm gear to drive the threaded rod. I took this image quick, using 10 fps, and it has bad onion skinning, but the detail is pretty good. T took 1000 frames and used most of them for this image:
This was the only image I was able to take, as it clouded up soon after. It was partly cloudy when I took this image, which is why I only took the one at the faster frame rate. Detail in the SEB is better. The GRS looks like its about to rise, as you can see it on the western limb. I was never able to resolve it that close to the edge before. Once I get the bugs worked out, I believe this will be a very useful tool.
I also didnt have it aligned quite right, as the image creeped upward on the screen. It is probably an error in the construction as to the elevation of the north pole. I'm not certain it can be totally fixed, but I will attempt to elevate the north side of the platform to correct the error. This Ponset is a test platform. Its pretty ugly, and i did hurry to build the wooden parts just to see if it works, which it appears to. I may build another, while paying more attention to detail.
