About two months ago, someone posted to our local astronomy club that they knew someone wanting to sell their old telescope. I contacted them and dropped by to check it out as they were only 10 minutes from my home. It turns out that telescope was the Takahashi Epsilon 200. A scope made around 1984-86. It was designed for film photography, and has a large corrected circle of about 60mm. I knew that would be large enough to cover my full frame sensor, so I went about getting all the parts to make this telescope work with a modern sensor and equipment.

I first added Parallax 10" rings, Losmandy dovetail plates, and a precise parts adapter to get as much clear aperture as possible to the camera sensor. I also got a ZWO EAF focuser for automated focusing.

I've never owned a Newtonian telescope, so this is my first experience with it, and first image! One thing I noticed as I started looking at the first few frames coming off the telescope was that I collimated it wrong. And after watching some YouTube videos I now know the right way to do it. But this image is uncollimated, and has no tilt removed. This first image is really a test of the scope and the setup, and despite some of the edge star issues, I'm very excited at the possibilities, and extremely pleased with the overall quality of the first image.

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
