I just purchased and EDGE HD 11" with the .7 focal reducer. I want to know how to attach my QSI683WSG-8 to the focal reducer and achieve the correct amount of back focus. 

 

Thanks in advance for your help!

Claude

You want to get the Celestron T-Adapter for the 11” Edge. It’s about the size of a coffee can but will put your camera at the correct back focus.

Look at these 2 documents from qsi and it will help you determine the amount of spacers that you will need to add to the camera face after buying and installing the Celestron T-Adapter.

I connected my QSI683WSG-8 to the T adapter and .7 reducer to the C11 and achieved FWHM of 2.5! Thank you for your answers.
