Milton:

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 prefer guide scopes, but clearly I've had flexure

issues the way I set up last to do that.  

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 may be leaning toward a Flea2 with 1024x768 pixels, then, since I

already have a 640x480 Flea.  Any experience out there with the

Scorpions?

One other nice thing about the Flea2 is that if you have a FireWire

800 port on your laptop, then you can run the 640x480 Flea on th FW400

port and the Flea2 on the FW800 port and don't to use a FW Hub.

That's what I'm doing tonight with the C8 scope, a Celestron Radial

Guider, the Flea2 (for guiding) and a Flea (Imaging). My big problem

has been finding the correct spacer combinations so that I can get

both cameras in focus at the same time.

TTYL..
