Product Overview The RAEXK is Losmandy's G11 RA extension kit, and it exists to allow a meridian flip through. It adds 1.5 inches to the RA body and raises the saddle plate by 0.6 inches, which is enough clearance that the motors no longer interfere when the mount flips through the meridian. It also makes the DEC axis easy to remove for lighter transport. The kit is for G11 mounts with non-tucked motors. Who It's For This solves a problem that only shows up in the middle of an imaging night. A German equatorial has to flip when the target crosses the meridian, and on a non-tucked G11 the motors can foul before the flip completes — which means either stopping the sequence early or intervening at the mount. The extra 1.5 inches of RA body and 0.6 inches of saddle height buys the clearance to flip straight through, unattended. Key Features & Design Allows a meridian flip through without the motors interfering. Adds 1.5 inches to the RA body. Raises the saddle plate by 0.6 inches. Allows the DEC axis to be removed easily for lighter, simpler transport. For G11 mounts with non-tucked motors. Recommended Uses Unattended or automated imaging that must flip at the meridian. Long imaging sequences on a target that transits mid-session. Splitting the head for transport by removing the DEC axis. Bringing an older non-tucked G11 closer to the clearance of the current design. Compatibility and Accessory Notes Mounts: G11 with non-tucked motors. For the newer tucked-motor G11G and GM811G, the RA extension dovetail is the corresponding part — tell us which motors you have and we will confirm. Axis swaps: the easy DEC removal pairs well with the G11 DEC axis and GM8 DEC axis if you switch configurations. Saddle height: raising the saddle 0.6 inches moves the instrument slightly further from the declination axis, which shifts the balance point a little — no more than a counterweight adjustment. Counterweights: we stock the 7 lb, 11 lb and 21 lb weights if rebalancing calls for a change. Good to Know Before You Order Tucked or non-tucked motors decides which part you need. This kit is for non-tucked G11 mounts. Send us a photo of the motor area if you are unsure and we will identify it. It changes the geometry of the mount slightly — 1.5 inches on the RA body, 0.6 inches at the saddle. Worth knowing if you work to a fixed pier height or a tight observatory clearance. The meridian flip benefit is specific to motor interference. If your flips already complete cleanly, the transport benefit is the reason to fit it rather than the clearance. Losmandy publishes no weight for this kit. Specifications are Losmandy's published figures. Frequently Asked Questions Is it difficult to set up? It is a mechanical fit between the RA body and the DEC axis, done once on a bench. Afterwards the mount simply has more clearance, and the DEC axis lifts off easily. What is a meridian flip through? When a target crosses the meridian, a German equatorial has to swing the telescope to the other side of the mount. Flipping through means completing that without anything fouling — which is what this kit buys on a non-tucked G11. Which mounts does it fit? G11 mounts with non-tucked motors. Tucked-motor mounts take the RA extension dovetail instead. Will it change my balance? Slightly — the saddle sits 0.6 inches higher. A counterweight adjustment covers it. Does it help with transport? Yes. Losmandy lists easy DEC axis removal as a feature of the kit, which makes the head lighter to carry in pieces. Bottom Line In short: the G11 RA extension kit for non-tucked motors — 1.5 inches added to the RA body and 0.6 inches at the saddle, enough clearance to flip through the meridian, plus easy DEC removal for transport.
