Well made with clear and clean threads throughout. Screwed onto the back of my Maksutov without issue and I then fitted a 2 visual back. Perfect

Well made piece

This adapter was easily spun onto the thread of my Skywatcher 127, making it possible to use standard SCT accessories.

Mak to sct adapter
Tuesday, 26 January 2021  | 

Installed on a mak 127. Simply remove mak visual back to reveal thread and screw on adapter. Only 3 stars because it is overpriced. A big thank you to garnett Leary who's YouTube video inspired me to do this mod

Sct adapter stiff does not screw in
Thursday, 24 September 2020  | 

Only screws in one turn and stops, does not seem to have the right threading for mak 127 skywatcher


The adapter thread hasn't changed but occasionally there is some variation with the telescope thread.
Please check there isn't paint or debris in the adapter or telescope thread (a toothbrush is good for this). If that doesn't help then please contact us to arrange refund or replacement.

Stiff threads

Is it normal for this to only screw down half way this is my second one.


This should not be stiff but sometimes the tolerances can differ between telescopes. If you would like us to send you another one to try please get in touch but it may be the telescope itself that has some malformed threads.

Fits my Skymax 127 perfectly, used with Astro Essentials 2" Visual Back / Eyepiece Holder for SCT Telescopes i now have 2" imaging train for both my eyepieces and camera mounts. Nicely made and finished.

Nice to now have a standard SCT thread !
Monday, 22 April 2019  | 

The perfect solution to the awkward non-standard 45mm thread on early Skymax 127 scopes.
This adapter simply screws over it and can then be left in place permanently.
I can now use my existing (expensive !) SCT focuser and 2" diagonal.
I've given it 5 stars because it's nicely made, works perfectly, and "does exactly what it says on the tin".....
