Hi folks,

I haven't visited here for a while but have spent some fun times with my basic 4.5" Newt. I've taken some photographs of the moon by simply holding the camera up to the lense. :thumbsup: Now I'm ready to start something more serious, including buying a new and better scope.

I've seen a few of the Meade LX200 Classic's for sale here and elsewhere. They appear to be a good scope generally but I'm wondering how they would go for photography (planets and DSOs).

I know the Alt-Azimuth/fork mount isn't ideal of long exposure photography. Meade sell an "Ultrawedge". Can someone explain how this helps correct the rotation and what's the difference between a "wedge" and a "rotator"?

Thanks again,
Af.

P.S. I'm moving to Europe next year so a massive DOB or something like that wouldn't be ideal as I would like to take my equipment with me. :)

A wedge inclines your Alt/Az mount so that it's azimuth axis becomes the equatorial or RA axis, so that it can be used like a GEM.

Gotchya. Thanks for that rcheshire. :thanx:

I've decided on a GEM mount anyway - the thought of dealing with yet more angles on a wedge made my head hurt!
