Subject: Meade AR6 with Moonlite focuser Sent: Saturday, May 5, 2007 03:11:01 From: DMD COLLINS (email@example.com) I came across your site after researching a problem I have in trying to use a Moonlite Crayford focuser on my AR6. I have had the scope for about 3 - 4 years now, but was always reluctant to put a 2" diagonal and eyepieces in it, as the dovetail and screw system does not hold them securely, and also seems designed to scratch the diagonal barrel. After seeing the Moonlite Telescope Accessories ads recently, I bought a crayford design CF Model 2 focuser from them, specifically designed to replace the original focuser on the AR6. It is a beautiful piece of machinery, and you can imagine my disappointment when I put it on the tube only to find that it rattles about like a size 10 shoe on a size 6 foot! It is impossible to clamp it securely onto the tube, the gap between the inner and outer flanges on the MTA focuser is about twice the thickness of the tube wall, and cannot be compressed. I got in touch with Ron Newman at MTA, who was very helpful and explained about the Meade system of using tape on the outside of the rear edge of the tube to fill the gap between the tube and focuser. He said the MTA focuser was designed to take account of this tape. This was news to me, I had never heard of this tape and my tube definitely doesn't have any on it, the Meade focuser is a tight fit on the tube through its own design. Have you any experience of this problem? I am stuck with a lovely MTA focuser I can't use unless I find a way to fill this gap and get a secure clamp. Help!!! Danny CollinsMike here: I don't have either an AR or the Moonlite focuser so can't comment directly. But I don't think you should feel stuck with the MTA focuser; since it doesn't work on your model I would think they would take it back with a full refund. However, perhaps someone else has experience with these and can offer a solution.
