Sounds like a nice way to rig up.

I've got a Lumicon easy guider, but I've never been successful at

finding a guide star with off-axis guiders before I gave up in

frustration.

I tried it last night and it is probably going to be a PITA to use.

I prefer guide scopes, but clearly I've had flexure

issues the way I set up last to do that.

That has been my issue in the past too with my MAK127 and 80 mm guide scope rig, for both both flexure and mirror movement. And it gets worse as you increase the focal length.

My next plan is to build a guidescope that's very light and rigid, and

as low profile as I can make it so that it can stay mounted on my

C9.25 and fit below the roof when I stow the 9.25. The Megrez won't

do that. Also, I plan to use the collimation screws on the primary

mirror (I've got a couple I could use - a 4.25" f/5.5, and a 3" f/6,

believe it or not) for boresighting with the main scope. And if I use

the 4.25", there won't be a secondary mirror - I'll just mount the

flea at the prime focus. ...that's what's so great about the fleas!

I would love to get the FASTAR unit for my C8 and then rig it up with a Flea or a Flea2. Other than the FireWire cable, the Flea would not block any light at all and running at F1.9 (40' x 30' field of view) would be a nice light bucket.
