Make sure you re-align it when you set up your scope for imaging as well, unless you just move it out on a dolly without taking it apart. Did you see the Orion nebula in your finderscope when you tried?
[/quote]did a 30s exposure and seemed to get a cluster of something but not sure. have a canon 40d coming so i can use live view and nebulosity to get a decent focus, that should help. put together a 10 shot composite of the moon and a shot of saturn both from last night, the barlow helps a lot:)

It might be a finderscope issue. If you have a hard time getting what you see in the FOV, make sure that what you have in your cross hairs is visible in your OTA.The finders can get out of whack pretty easy with all of the hauling around involved. Orion's sword is a big target, you shouldn't have had too hard a time picking that one up.
[/quote]k i'll get out tomorrow in the day and make sure they're all lined up, i think it is a bit off yeah

Did you check to make sure the nebula was in your field of view? The sword of Orion is a big place when you're talking about 30 arcminutes Field of View. The nebula can be faintly seen in 10 seconds for sure.
[/quote]yeah i wasn't too precise in aiming the scope, i guess without a go-to mount i'm a little lost trying to find something like that. i'll use cart du ciel and really zoom in on on the location to try and get a better fix on it- thanks:)
i went to the keller parking lot as suggested twice now, last night and a couple days ago. it's a good spot. figured out how to use the celestron 8 and got a few shots with my DSLR. waiting on the radial guider and a barlow to complete the setup:) saturn is tiny without the barlow but the moon was alright. focus wasn't too good i have to set up a directory monitoring program on my laptop to help with focus. here's what i got last night:
also question about nebulas, i pointed my scope at the sword of orion last night before it set, and did a few 5 min exposures just to see what i could pick up. didn't seem to capture anything on the image but stars, is that because of the IR filter in the camera? i thought i'd get a hint of something at least. karsten
