Peter,
the CF tube is another labour of love and as you can see from the reflections I ran out of love, and settled for "she'll be right".
Nope, the Lodestar is a fixture, screwed in place. I always find a guide-star.
If I am imaging (and by default therefore the guide-scope is also looking at) something like M42 or the Tarantula or Omega Cent (only really been at these ones since I got the Lodestar), I can normally see the nebulosity easily in a one second shot. Try the DSI and see.
The way I see it, the camera alignment means little to the image, so the closer all that weight is to the polar axis the less I need to have out the other side. I am tempted to dispense altogether with the finder, it is an RA job, which makes life slightly easier, but once I am aligned and synched I never use it again all night.
I have a copy-cat setup with the AT8" newt as well, simple swap the OTA only and go for it.
Gary
