I have a Celestron 102 widefield Refr. I would like use it with my 35mm. OM-1.
here is the problem; without a diagonal I find I have to hold my camera at least 2 or more inches behind the fully extended drawtube. Is there an adapter I can get to make up the distance? or am I just going to have to use the dia.? thank you, John Meiners, Astoria, OR.

All you need is something called an "extension tube". Don't know if the 102 has one available, but probably just about any would fit, since the focuser is fairly standard. You'd just have to make sure the threads match. I have one for my TV Genesis and my son has one for his Orion ST-80, so I'm sure they're widely available...
