I research a very short T-Thread Visual Back for SCT's to adapt my ST-10XME/CFW-8A close to my Meade f/6.3 focal reducer, to avoid elongated stars in the edges of my pictures.
I have the SBIG T-Thread (16mm) but it is too long to use it with the f/6.3 focal reducer + CFW-8A + ST-10XME (the ST-10 chip is too far).
A T-Thread Visual Back for SCT's as short as the model used in the Meade f/3.3 focal reducer package will be perfect.
If you have that (made, brand or other), I am very very interested.
I wait your messages impatiently. Thank you.
