Solar B Posted May 27, 2011 Share #21 Posted May 27, 2011 Advertisement (gone after registration) I recommend a sechondhand ... HEQ5 or if goto is a must then the Pro version also secondhand ... then you can work out if you really need goto or not without loosing any cash ... EQ6s are a lot heavier and a HEQ5 will easily handle your GSO. Brian Link to post Share on other sites More sharing options...
Advertisement Posted May 27, 2011 Posted May 27, 2011 Hi Solar B, Take a look here Astrophotography. I'm sure you'll find what you were looking for!
luxikon Posted May 27, 2011 Author Share #22 Posted May 27, 2011 Brian, no, goto is no must. It may be even better to start without it. Is the HEQ5 able to track in Right Ascension without the goto? Link to post Share on other sites More sharing options...
Solar B Posted May 27, 2011 Share #23 Posted May 27, 2011 Yes it will and if you buy a normal Black one then you can add the Goto option later if required the Pro versions are White in colour , a HEQ5 is all you need unless you are looking to use a much larger scope in the future....but buy a used one.

Solar B Posted May 27, 2011 Share #24 Posted May 27, 2011 Oh and Klaus if i may say i think that hanging an M9 of the side of a telescope would be a "very" unnerving experience ... i would use a regular Canon (better suited anyway) and not a FF masterpiece.

luxikon Posted May 28, 2011 Author Share #25 Posted May 28, 2011 Because I still need some expensive astro equipment there is no money left for a DSLR at the moment. What about a M6 or a film based 135 SLR or even 120? Link to post Share on other sites More sharing options...
Solar B Posted May 28, 2011 Share #26 Posted May 28, 2011 I know how expensive astro equipment can become ... i like the idea of you using an M6 that sounds very retro for AP ... but its still quite a valuable camera !!!! I guess you can only really use what you have ... but an M9s a bit too good Brian Link to post Share on other sites More sharing options...
luxikon Posted May 28, 2011 Author Share #27 Posted May 28, 2011 Advertisement (gone after registration) "I guess you can only really use what you have ..." I've got one. The only question is whether it works with my Visoflex on a 8'' Newton telescope. Or will it be "a 'very' unnerving experience" too Link to post Share on other sites More sharing options...
AlanJW Posted May 29, 2011 Share #28 Posted May 29, 2011 If you're going film, I think it would have to be a SLR. How would you focus with a RF? Unless you use a Visoflex, of course.

pop Posted May 29, 2011 Share #29 Posted May 29, 2011 How would you focus with a RF? Apologies if this is a daft question. I always thought that the distance to astronomical objects was infinite. Is there any need to focus? Link to post Share on other sites More sharing options...
-ph- Posted May 29, 2011 Share #30 Posted May 29, 2011 As telescopes do not have a fixed mount where you would attach the camera, it is not known where exactly their focus point is. So an attached camera can focus well beyond infinity. By the way, most SLR-lenses focus beyond infinity too. In my experience with astrophotography, a live-view enabled camera is the way to go. Canon DSLRs are very common for astrophotography, as their sensor technology allows for long exposure times without a mandatory dark frame after each picture, like the M9 takes. So my advice would be to get the cheapest Canon which has live view and optionally have it converted for astrophotography, which means removing the infrared filter built in to increase the sensitivity in the far red spectrum.

LCL999 Posted May 29, 2015 Share #31 Posted May 29, 2015 I had no trouble attaching my M9 to a Telyt 400mm f5.0 lens. The sequence is lens with LTM screw mount into a 16466M adapter (LTM to M-bayonet) M-bayonet into a Viso-III then m-bayonet into the M9. I got some pics but my star tracking hardware needs more careful setting up. What I would like is to attach a 90 degree diagonal and eye-piece, but I cannot find a LTM to T-mount adapter (T-mount is the standard for telescope bits and pieces - 42mm x 0.75 pitch). The microscope attachment might be a good alternative. Could someone please tell me the part number so I can search for it. Cheers Link to post Share on other sites More sharing options...
