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.

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.

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.

I know how expensive astro equipment can become ... i like the idea of you using

 

an M6 that sounds very retro for AP :cool: ... but its still quite a valuable camera !!!!

 

I guess you can only really use what you have ... but an M9s a bit too good :eek:

"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

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. The beauty of a DSLRis focusing the telescope via live view.

Apologies if this is a daft question. I always thought that the distance to astronomical objects was infinite. Is there any need to focus?

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.

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
