Urgent adaptor help :)

[hms_furious]

 

Hi all, I am looking at the above that Solar B has for sale but I am struggling to find a good and reasonably priced set of adaptors to make it work with my 127 mak. It is a new one so currently there is a thread on the OTA and then a straight bit with a nut that attaches the cheapo diagonal unit itself onto.

Any pointer would be really appreciated. Thanks

Is the thread on the back of the 127 Mak an SCT thread? (50.8mm diameter)

If so you just need an SCT to 2" visual back like this...

Thanks. I have just unscrewed it and it looks closer to 45mm edge to edge....

In that case you will need one of these...
