PLUS support rings are available in different diameters in order to fit different telescopes. All of them are provided with holes and threaded holes for M6 screws in order to let you easily connect to all the other PLUS elements like dovetail bars, guide rings and EAGLE control units. In fact we specifically designed the PLUS system to allow you connect all the elements with at least 2 screws and avoid flexures. Let’s see how to use PLUS support rings with PLUS dovetail bars, guide rings and EAGLE.
In this video Filippo shows you how to connect PLUS support rings to the other PLUS elements like dovetail bars, guide rings and EAGLE control units:
In order to connect PLUS support rings to PLUS Vixen-style dovetail bars, you can use 2 M6x12 screws, inserting every screw from the internal part of the ring and screwing it into the corresponding M6 thread in the Vixen-style dovetail bar. This way the M6 screw head will be inside the ring and it won’t touch the telescope tube.
Instead, if you have a PLUS Losmandy-style dovetail bar, you can use 2 M6x12 screws for every support ring, inserting the screw from the bottom side of the bar in the corresponding passing holes. This way the M6 screw head will be inside the dovetail bar and it won’t touch the mount head when you will connect the dovetail bar to the clamp.
If you want to have a guide telescope in parallel to the main telescope, you can install the PLUS guide rings (that are available in 80mm and 115mm diameters) above the PLUS guide rings. In order to do this, you can use 2 M6x8 screws for every guide ring and insert every screw from the internal part of the support ring.
PLUS support rings are designed also to let you connect the EAGLE directly on top of them. This way, together with the dovetail bar installed below the PLUS support ring, you create a cage around your telescope and avoid any flexure. In order to connect the EAGLE to the PLUS support ring, you can use 2 M6x10 screw for every ring, inserting every screw from the internal part of the ring. Just note that, in order to connect EAGLE to PLUS support rings, avoid to use too long screws that may touch the internal electronics of the EAGLE. Threaded part of the screw that exits from the support ring has to be no longer than 6mm.
