William Optics FLT110 F6.5 TEC - Flattener Backfocus

[rab722]

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.

This maybe?

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.

Hello Rick, 

I have the flattener shown in the Robindonne post, I've added a few measurements that may help... I think the optics would be the same in both versions as they would have been specified by WO.

Please substitute depth for length where necessary...
