Hi everyone,

I recently bought a new Canon 450D SLR, and the appropriate T-ring and adapter to attach it.

At the moment the only thing I have to attach it _to_ is a little Celestron Astromaster 130mm newtonian with the world's most wobbly focuser assembly.

I assembled the various bits onto the camera for the first time last night, and wandered out into the front yard with the intent of grabbing a couple of shots of the moon to get the hang of it, and learn a bit more about which exposure/ISO settings, etc. were better/worse.

Unfortunately, I could not get a decent image in prime focus configuration no matter what I did. I'm wondering if the focuser travel on my scope is insufficient, or if I've done something obviously stupid along the way? :-)

The adapter is a Prostar variable length job, allegedly suited to both eyepiece projection and prime focus work. Eyepiece projection _did_ work, but I'd like to be get things working properly at prime focus.

Any suggestions or "you connected it up _that_ way?!?!" comments gratefully appreciated. :-)

Cheers,
Chris
