  • Celestron Dovetail Accessory Bar, RASA 8

    The Celestron Dovetail Accessory Bar adds a second CGE dovetail rail to the top of your Rowe-Ackermann Schmidt Astrograph 8" optical tube. It accepts accessories that mount onto CGE or Losmandy D-series dovetail plates, creating a secure, integrated platform for mounting guide scopes, electronic focusers, and other imaging accessories. It installs easily into the existing threaded holes on the optical tube, with all required mounting hardware included.

    Top-Side Accessory Mounting for the RASA 8

    The RASA 8" is a dedicated imaging instrument that often requires multiple accessories running simultaneously. This top-side dovetail bar provides the necessary real estate to mount a guide scope for precise tracking or to attach control boxes and other hardware, keeping your setup clean and organized. By placing accessories directly opposite the main mounting rail, you can also improve the overall balance of your imaging rig on the mount.

    CGE Dovetail Format

    Celestron describes it as a CGE dovetail accessory bar that is also compatible with accessories which work on Losmandy-D plates, so it takes a wide range of guide scope rings and accessory plates. It bolts into the existing threaded holes on the top of the tube without any modification.

  • What accessories can I mount on the Celestron Dovetail Bar for the RASA 8?

    This CGE dovetail bar accepts accessories made for CGE or Losmandy D-series dovetail plates. You can mount any accessory that uses a corresponding saddle clamp, such as guide scope rings, piggyback camera adapters, or mounting plates for focus controllers and USB hubs.

    How does the Celestron RASA 8 Dovetail Accessory Bar install on the telescope?

    Installation is straightforward. The bar is designed to mount directly to the existing factory-drilled threaded holes on the top of the RASA 8" optical tube. All necessary mounting hardware is included for a secure attachment.

    Can I use this bar to mount a guide scope on my RASA 8?

    Absolutely. Mounting a guide scope is the primary reason for adding this accessory bar. It provides a stable, secure platform for a secondary scope, allowing you to achieve the long, precisely guided exposures that the RASA 8" is designed for.

    If I mount a heavy accessory on the RASA 8 using this bar, will it be stable?

    Yes, within your mount's capacity. The bar bolts into the telescope's existing threaded holes with the supplied screws and washers, and Celestron intends it for accessories such as an optional guidescope. Rebalance the telescope after adding accessories.
