Follow the (little) GOTO

What do you think of this idea:

Bring along a little GOTO like the NexStar 80, and match the red-dot of your big scope to that of the little guy. Even better, put a laser beam on the N80 and everybody can point their scopes at the spot. Any problems you forsee?

This would save some big bucks retrofitting a large mount.

I hate the idea of the green laser. I go to a lot of trouble to find a dark sky, and have somebody who thinks his observing program is more important flashing a big green light into the night?????

(However, I like the idea of using a cheap goto as a sky atlas.)

Is the idea that the laser puts a spot on the sky? Just how thick is your atmosphere?

I got the LXD55 mount for my MN56 just for this purpose. I was going to use it as a 'finder' for my CI700 mounted 10" SCT. Once it located an object, I would look in its red dot finder and then point the telrad on my 10" scopte to the same spot. I can then matched the star fields in SCT's ST80 finder to the MN56's FOV. That should get you very close. Plus, I will have a wide field of it in the MN56 and higher mag view of it with the 10" SCT. However, the Autostar died so I haven't tried out the idea yet. I have a replacement Autostar coming so I will try this out soon.

Right now, I just star hop with SCT and that's fine. There are nights when this combo would be very useful.
