Which telescopes are compatible with the PrimaLuceLab 155mm PLUS Support Rings?
These rings are designed for any telescope with an optical tube diameter of approximately 155mm. They are a confirmed fit for high-end refractors like the Takahashi FS-152 and Takahashi TOA-130.
What accessories can I attach to the 155mm PLUS Support Rings?
The rings feature the versatile PLUS system of threaded holes and slots, allowing you to attach a wide range of accessories. Common additions include:
-
Top and bottom dovetail plates (Vixen or Losmandy style) for mounting and for accessory attachment.
-
Guide rings and guide scopes for autoguiding.
-
Dovetail clamps to mount other hardware like an EAGLE control computer.
How do the 155mm PLUS rings help balance a Takahashi TOA-130 with a guide scope?
By attaching a PLUS dovetail plate to the top of the 155mm rings, you create a stable platform for your guide scope. You can then slide the guide scope assembly forward or backward to achieve perfect declination balance. A second, longer dovetail plate on the bottom allows you to adjust the entire telescope package for right ascension balance on the mount.
What are the PrimaLuceLab 155mm PLUS rings made from?
They are precision CNC machined from a single block of aluminum. This process ensures superior strength and dimensional accuracy. The rings are then sandblasted and hard-anodized to protect them from corrosion and wear.
Can I use non-PrimaLuceLab plates with these 155mm rings?
Yes. While designed for the PLUS system, the rings include a series of central slots. These slots allow you to attach plates or other accessories from different manufacturers using standard screws, offering broad compatibility with your existing equipment.
I want to mount my Takahashi FS-152 on a Losmandy-style mount. What else do I need with the 155mm PLUS rings?
To mount your FS-152, you will need the 155mm PLUS rings and a PLUS Losmandy-style dovetail plate. You would attach the rings to the dovetail plate, then clamp the entire assembly into your Losmandy-compatible mount saddle. The length of the plate depends on your balancing needs; longer plates offer more room for adjustment.
