Default Need Help!

I just got a Celestron T-mount adaptor for the Canon EOS (#93419) and a Meade 1.25'' basic camera adaptor (07356) to fit my Canon Digital Rebel to my Meade ETX. Everything fits just fine, but for some reason I'm having trouble focusing on far away objects. It can focus perfectly on objects within 100 or 200 feet, but anything further than that is a fuzzy blob. The telescope works just fine without the camera attached, and the camera works just fine on it's own too. Am I doing something wrong? Maybe missing an adaptor or using an incorrect one?

Help!

Hello Brandonv, i've got the Meade ETX 70 and i have the same problem, i'm using the Canon eos 400d but i don't think the problem is the camera but the telescope, not enough back focus. I cant focus my webcam, Meade DSI or my eos 400D. Sorry can't give you a solution but at least you now know you're not alone. If I find a solution i will let you know.

Hi brandonv. What model of ETX are you using? It sounds like you may be having a problem with focusing due to insufficient "in-travel" of the focusing mechanism. Do you run out of room when you try to focus at a more distant object? If so, perhaps you may be able to achieve focus with a shorter adapter than the Meade basic camera adaptor. Just a thought. Hope this helps.

One other idea I just thought of would be perhaps if you checked on Mike Weasner's website. He has a ton of information for all models of ETX's, and it's broken down by ETX model. His site is at http://www.weasner.com/etx/menu.html
If you scroll down, and look under the heading, "Feeback", you should see your ETX model listed. I bet someone else has tried the same setup you have, and may have experienced the exact problem you're describing. If so, they probably have a solution or a work-around for it. Mike's site is very interesting and informative, and he also gives a lot of good "tweaks" on how to tune your ETX to make it work the best. He keeps older messages as well in the Archives area.

Good luck!

Paul
