Where doe the OAG fit in the chain?

[Earl]

This is for use with my C11

My Current setup is:

Atik > Filter wheel with adapters > Spacers > T to SCT adapter > Antares Reducer corrector.

I think replace the spacers and t to sct adapter. there is 19mm here.

That might be tricky, so can the OAG go before the Reducer?

[steppenwolf]

The OAG should go in between the T to SCT adapter and the filter wheel.

Just to confrim, in the red box on the image?

The OAG can go anywhere in front of the filter wheel. In front of the reducer if needs be.

(The Lumicon GEG guider positions the pick off prism in front of the reducer lens.)

The extension tubes required etc to get parfocal alignment between the guide and the imaging camera will obviously be different.
