Robtics Maksutov to SCT Adapter - Use SCT accessories with Maskutov telescopes

With this Robtics adapter you can use accessories with SCT thread with telescopes that have Maksutov thread.

Adapter ring to convert the thread on the rear cell of many Maksutov-Cassegrain telescopes (including some of those made by Sky-Watcher, Celestron, Orion and others) to an SCT (Schmidt-Cassegrain) thread. Allows you to use SCT threaded diagonals, visual backs, focal reducers and other accessories on your Mak-Cass telescope. Has female Maksutov-Cassegrain threads on the inside all the way through and male SCT threads on the outside at one end. Precision machined from aluminum and black anodized.

Please note that the focusing knob on some Maksutov telescopes is quite close to the rear cell and there is a possibility that a 2" accessory coupled with this adapter may not screw on to your scope since the focus knob gets in the way. Please measure the separation between the focus knob and the 2" accessory you plan to use to ensure that you will be able to use SCT accessories on your Mak using this adapter.

Note also that this adapter will NOT work with the Celestron NexStar, C-90, C-130 and Meade ETX series of telescopes since those do not use a standard Mak 44.5mm thread. Many of these other scopes use a smaller 35mm thread. So please make sure you measure your scope's thread diameter before purchasing this adapter to make sure it will fit.

This adapter also includes a rubber ring that is an SCT thread spacer. You will not need it for most applications, but should you find out that your SCT diagonal or other accessory does not lock when screwed into this adapter and keeps on spinning, just insert this into the female SCT thread of your accessory to resolve the issue. This will happen if the female SCT thread of your accessory is longer than the male SCT thread of this Robtics adapter.
