Quote:Thanks, guys. I've checked Paul's Youtube Channel, and performed the tuneup, but I don't see anything there about disassembling the drives.

Quote:Thanks, Falcon and Astronewb. The sensor on the camera is a micro 4/3 (13mm H x 17.3mm W). I took 5 shots of 2 minutes each, but with the save time of the camera the time for the run was 5 minutes/shot, or 25 minutes total. I used the iPhone app to place Polaris, but I suspect I may have had the mount head too loose. I'll try drift aligning next time.

Quote:Has anyone tried putting a C8 on the mount along with a small 68 to 80mm refractor piggybacked or side by side mounted? I'm thinking maybe that configuration would overload the ZEQ25? Any thoughts on that from anyone?Patrick

Quote:That's a great setup Wes, camera and guider in line over the mount, I like that. I see you're using rubber bands on the focus ring?Have you ever thought about a fine adjusting ring set like this:

Quote:Thanks Mike and boandpokey
This was my setup the only other time I have managed to get my ZEQ25 out for astrophotography.
In the foreground is the ZEQ25 (1.5" tripod) with a two cameras (one with a "Tair-3s" 300mm f/4.5 camera lens, the other with a 50mm f/1.8 lens) and the same 50mm guide-scope.
In the background is my CI-700 (on an adapted CG5 2" tripod) with 492 digital drive and NGC-MAX push-to setup driving an AT6RC, a 3rd DSLR and an OAG based guider.
So... three cameras (all different models) three optics at vastly different focal lengths and two mounts with very different control systems.... Is it any wonder that I did not have the time to properly investigate the ZEQ25's guiding behaviour that session?
You know I almost bought a CI-700 instead of the zeq25. Its cool to see them both setup like this for the sunset. I am however glad I went with the zeq. it has really turned out to be a performer.
