What is the Baader 3" 60mm Losmandy Rider Clamp used for?
The Baader Rider Clamp is used to add a secure mounting point on top of an existing 3-inch Losmandy-style dovetail bar. Baader makes it for holding Baader guidescope rings or a V-clamp, so you can carry a guide scope in rings or a Vixen-style bar in the V-clamp on top of your main telescope.
Will the Baader 3" Rider Clamp fit any Losmandy-style dovetail bar?
Yes, this clamp is designed to fit the industry-standard 3-inch Losmandy "D" profile. It will securely attach to dovetail bars from Losmandy, Celestron (CGE), and other manufacturers that adhere to this specification.
How does this Baader clamp prevent damage to my dovetail bar?
High-end clamps like this Baader model use a jaw that makes full-surface contact with the angled side of the dovetail bar. This distributes the clamping force evenly across a wide area, unlike a simple set screw which concentrates all the pressure on a single point. This design prevents scratches, dents, and other damage to your dovetail bar's finish.
Can I use the Baader 60mm Rider Clamp to mount a heavy guide scope on my 11" SCT's Losmandy bar?
Yes, if the guide scope sits in Baader guidescope rings or on a Vixen-style bar held by a Baader V-clamp; the rider clamp holds either on the 3-inch bar. Baader gives no load rating, so check the weight of your guide scope.
What's the best way to attach a DSLR and lens piggyback style to a refractor using the Baader 3" Rider Clamp?
You would first mount the Baader Rider Clamp onto the dovetail bar on top of your refractor. Then, you would typically attach a second, smaller dovetail bar (like a Vixen-style bar) to the base of your DSLR or lens mounting ring. This smaller bar can then be clamped into a saddle attached to the top of the Baader Rider Clamp, creating a secure, multi-layered system.
Does the Baader 3" 60mm Losmandy Rider Clamp include mounting screws?
Baader lists screws as not included. The required screw length and thread type depend entirely on the accessory and saddle you are attaching it to. You will need to source the appropriate screws for your specific application.
