Here are some pictures of my equipment and imaging setups.
Below is a picture of my FSQ setup.
The bottom plate is Losmandy DUP.
The rings are standard Parallax 114mm rings drilled for AP pattern. The riser blocks are the Losmandy AP riser blocks on top
and bottom (to allow FSQ parts clearance). The devices on top of the upper riser blocks are Losmandy universal adapters. They
make the top of rings become a virtual dovetail saddle. I can then place anything mounted on a dovetail plate as piggyback
on top of the FSQ. In this case, I have my standard FS60C guider setup. I like the large rings with adjuster screws because
it gives me great flexibility in setting up guide stars. These large rings are Losmandy 125mm guide rings. I have used this
setup frequently and it works very well.
