I mentioned a few days ago machining a Vixen dovetail plate. But I decided to buy one from Agena Astro made by Baader Astronomical in Germany. Aluminum is less likely to fail than acetal (not that I would worry about the piece that I machined out of acetal). Unlike my plate and even the Televue Vixen dovetail adapter, this is a true dovetail, intended to fit tightly in a Vixen shoe, and only capable of leaving at the ends not the top. The slot for 1/4"-20 screws is nearly the entire length so I can pick almost anywhere to install the scope rings. The plate is not flat on top but two slightly diagonal ramps, so it fits a variety of circular rings. Even the flat bottomed rings for my baby reflector locked in very tightly.
Clayton,
ReplyDeleteI've been experimenting with astrophotography with my Nikon and some lengthy (70-300mm/200-500mm) Nikon F-mount zoom lenses but want to reach out a bit farther. Can you recommend a good tutorial on getting started with reflector telescopes and DSLR/mirrorless cameras? That side of the optics is totally new to me.
Thanks for all you do!
Kevin
I cannot think of one. Tell me what you know and I fill in the gaps.
