  • Secure telescope mounting with CGE and Losmandy-D dovetail compatibility

  • Exact fit engineered for the 8" Rowe-Ackermann Schmidt Astrograph
  • Durable construction withstands repeated field use
  • Enables accessory attachment via standard dovetail plates

Purpose-built dovetail bar for 8" RASA

This Celestron dovetail bar is made specifically for the 8-inch Rowe-Ackermann Schmidt Astrograph optical tube. It provides a secure connection to a mount, minimising vibrations that can degrade astrophotography images. The bar accepts CGE or Losmandy-D dovetail plates for broad accessory compatibility.

Upgrading from generic or improvised mounting

The bar replaces makeshift or universal dovetail solutions that can introduce flex or misalignment on the 8" RASA. The improvement is worth it when precise balancing and repeatable alignment are required for long-exposure imaging sessions.

Straightforward installation with standard plates

The bar bolts to the top of the RASA 8 tube and mates directly with CGE or Losmandy-D dovetail plates, so no specialised tools are needed. The main pitfall is under-tightening the mounting screws, which can allow the tube to shift during tracking.

Questions about this item

Which dovetail standard does the bar use to mount the 8" RASA tube on my mount?

The bar fits CGE or Losmandy-D dovetail plates, matching the two most common saddle types on equatorial mounts.

How do I attach the bar to the optical tube, and what step is often missed?

Bolt the bar to the factory threaded holes on top of the 8" RASA tube, then tighten the mount saddle clamps evenly; the step often missed is re-checking balance after the camera and accessories are installed.

What part of this bar is most likely to need replacement after heavy field use?

The anodised aluminium bar itself is durable, but the stainless-steel mounting screws can strip or corrode over time and are the typical replacement items.
