My widefield Lodestar setup
with Nikkor 180mm f2.8 lens and filter drawer on a ZEQ25 mount.
Here is a clearer close-up on the kitchen counter.
Finally all parts taken apart.
I list the parts from left to right.
1. Tripod attachment ring (from ebay) bolted to a 4" dovetail.
2. Nikon lens to M42 adapter (from ebay).
3. Teleskop Service filter drawer with T2 threads (with drawer halfway pulled out).
4. 15mm T2 spacer.
5. Teleskop Service camera rotator.
6. Teleskop Service 1.25" eyepiece holder with T2 threads.
7. Lodestar x2c with 1.25" parfocalizing ring attached (the yellow plastic ring is just decoration).
The 15mm spacer and the camera rotator are not essential. The round Lodestar can easily be rotated in the ep holder and with a parfocalizing ring it would not get out of focus. But since I had the rotator, I am using it. Also I feel more comfortable with the ep holder gripping the camera in its middle rather than at its end.
For the Pentax lenses I just use a "Pentax M42 lens to Nikon adapter" (from ebay) added to the front of the setup on the photo.
To illustrate the field of view achievable with the various lenses from 35mm to 300mm focal lengths, I collected captures of a few winter nebulae here. http://stargazerslou...r/26379-dom543/. They are sorted in the order of increasing FOV.
