Guest Posted March 29, 2013 Share Posted March 29, 2013 I have bought a 2nd hand DSLR and wish to connect it to my telescopes with a 1.25" fitting. Are the T-mounts the same for all cameras? I need to find out so I know what my daughter can get me for Father's Day. Link to comment Share on other sites More sharing options...
philjay Posted March 29, 2013 Share Posted March 29, 2013 Phil, using 1.25" fittings will cause vignetting, (I speak from experience because that's what I did when I started, used an old barlow). If the scope has a 2" focuser go for a 2" adaptor to make the most of your camera chip. Link to comment Share on other sites More sharing options...

dawson Posted March 30, 2013 Share Posted March 30, 2013 The fitting i've got for my canon eos is specific for the canon eos fitting on the camera side, but i suspect a standard screw thread on the other, but i'm still very new to this so wait for someone more knowledgable to come along.

+Graham Posted March 30, 2013 Share Posted March 30, 2013 (edited) Hi Phlip. The T ring is camera specific as it fits on the camera like a lens. What scope have you got.?? Edited March 30, 2013 by Graham Link to comment Share on other sites More sharing options...
Guest Posted March 30, 2013 Share Posted March 30, 2013 Thanks, Folks. I have a Skywatcher ST80 and SkyMax 127. I thought that camera lenses were a standard fitting on SLRs and DSLRs but perhaps I'm wrong. I have a Konica Mimolta, so a few years old. Hi Phlip. The T ring is camera specific as it fits on the camera like a lens. What scope have you got.?? Link to comment Share on other sites More sharing options...
+Graham Posted March 30, 2013 Share Posted March 30, 2013 Hi Phiip. Stick up a photo of the ep holder on your st 80 because I can fit my canon + t ring straight on to the focus tube of my st 80. Link to comment Share on other sites More sharing options...
Guest Adz_88 Posted June 23, 2013 Share Posted June 23, 2013 I am also looking to get into imaging I have found the odd bit of info I do have a 2" thread but as I'm a novice I want to get a cheep second hand dslr I was looking at Samsung but I can't find the t ring for a samsung just th usual canon pentaks. Anybody know where I can get one? Link to comment Share on other sites More sharing options...
glider Posted June 23, 2013 Share Posted June 23, 2013 As Graham says, get a Canon EOS T ring and it screws onto the end of the ST80 focuser and bye-passes the 1.25" EP holder that PhilJ rightly says will otherwise be a pain. Link to comment Share on other sites More sharing options...
Guest Adz_88 Posted June 23, 2013 Share Posted June 23, 2013 Ya I got that just can't get hold of a t ring for Samsung dslr Link to comment Share on other sites More sharing options...
dawson Posted June 23, 2013 Share Posted June 23, 2013 If they don't exist (i've not looked) can you get a samsung to canon conversion ring, then put a canon eos t2 adaptor ontop of that? James Link to comment Share on other sites More sharing options...
Guest endure Posted June 24, 2013 Share Posted June 24, 2013 Ya I got that just can't get hold of a t ring for Samsung dslr Which Samsung is it? A number of the Samsung DSLRs are actually Pentaxes in disguise. The telescope side of a T ring fitting is actually a standard T2 lens mount. The other side is specific to the lens fitting of your camera. http://en.wikipedia.org/wiki/T-mount Link to comment Share on other sites More sharing options...
Guest endure Posted June 24, 2013 Share Posted June 24, 2013 From Wiki: In 2005, Pentax Corporation partnered with Samsung Techwin[12] to share work on camera technologies and recapture market ground from Nikon and Canon. Then Pentax and Samsung started releasing new DSLR siblings from this agreement. The Pentax *istDS2 and *istDL2 also appeared as the Samsung GX-1S and GX-1L, while the jointly developed (90% Pentax and 10% Samsung) Pentax K10D and K20D gave birth to the Samsung GX-10 and GX-20 respectively. Some Pentax lenses are also rebranded and sold as the Samsung Schneider Kreuznach D-Xenon and D-Xenogon lenses for the Samsung DSLRs. However, both brands are completely compatible with Pentax and Samsung DSLRs. If you have one of the above a standard Pentax K T-ring should do the job.
