Rob, Yes, I do have a TEC-140ED. I think unfortunately it has assumed a back seat when I got my TEC180 and set up remotely only to have a huge number of technical issures with the camera, then the rotator, bad fittings, and finally a recent discovery that the TEC180 flange on the OTA was moving enough to negate any attempts to reliably remove tilt from a large sensor. At times I was so despondant that I didn't want to image with the "baby" scope. Big mistake, obviously. Now, I've seen the light. The TEC140 is quite amazing. So can be the TEC180 as I am extremely close to finally resolving the issues over the past 4 years!
