HI Lynn, Thank you.

I use an AP-27TVPH reducer with the TEC-140 and it works very well.

Hi Lynn,
I have the TEC flattener but it is not used with the reducer. The AP reducer does flatten some as well as reduce. If my chip was larger then it would not fit the circle and I would have to use the TEC Flattener instead.

I have a picture of the complete setup. It used off the shelf parts and adapters, Starlight (feathertouch) provided the focuser to reducer adapter. Then I used other parts from AP as I recall and some shims from McMaster Carr to set the distance. But the photo is labeled with all the parts. Send me a PM if you need more information or I could post the photo here.

Here is a photo of the setup. This should help visualize it.
