Sadly the owner of  Gemini Telescope Design  - Andras Dan has passed away. He was finishing up an E.Fric. mount for me when sent me an email that he was putting it on hold to go in for heart surgery. I found out  this week on Cloudy Nights that he died.

Does anyone know if he had anyone working with him that I could contact.

Yes, I got that drawing from William Optics but when I scaled it up the to the shown dimensions the flattener is not the one I have. I think its for the FLT110 F7 scope which is the generation after the one I have, the FLT110 F6.5 with TEC based optics. I have one in the the attached drawing that is about 10mm deeper. Plenty of dimensions to make it but not to use it.

Thanks for the response.

I just purchased the FLT110 with TEC optics scope and matching flattener also made by TEC . Does anyone use this combo and know the backfocus. I checked with both William Optics and TEC and neither could supply a number. This combo was sold >15 years ago and it appears no records exist.
