SCT compatible...

[RT65CB-SWL]

Good afternoon all.

Is this adapter compatible with the SCT thread?

If "No!",,,does anyone know if such an SCT adapter is available?

Tnx in adv.

What are you trying to achieve and what do you already have; posting a picture of what you want to attach to what may help.

You could use that M48 extension along with an SCT to M48  adapter I think.

It won't fit directly to an SCT, no.

Good evening and thank you for the replies.

The idea was to attach my SCT crayford focusser to the backplate of my ETX105...

...as the focus knob and shaft are in the way, even when fully wound in. The adapter ring is the Baader ETX-SCT one.
I have seen these SCT extension rings at www.scopestuff.com...

...and thought a variable one would be the better option.

In the meantime I will stick with my 1.25" helical focusser and SCT star diagonal.
