Alt-az for a big ol' refractor?
Posted 17 April 2011 - 05:20 PM
But with the OTA at 18.5 lbs., most alt-az mounts I've looked at just don't pack it (literally).
The Astro-Tech Voyager is spec'd "up to 20 pounds" (which is pretty much what the CG-5 is spec'd at). But I wonder if it'd really survive at that load.
Anyway, I'm sure I haven't seen everything out there. If anyone knows of an alt-az mount that would carry this big ... I'll go with "big 'ol", though I generally use a more colorful term ... refractor, I'd sure like to hear about it!

too much hoo-hah per ah-ha!
Can't help you, but I'm DEFINITELY stealing this for my list of sayings!

I have the DM-6 and love it and certainly think it would handle your cannon. The DiscMount site has lots of photographs showing big, heavy refractors mounted on the DM-6. Like all alt-azs, it is difficult at the zenith. The long, offset handle helps a lot--assuming the tripod does not interfere with it. Peters is a great guy to work with. Expensive? Yes. I don't know of a cheap solution. The T-Rex is also quite expensive.

Yeah, I've been noticing that ...

I may just have to bear the GEM (literally), until I find a used "mega-altaz".

For those who have recommended the GIRO mount, where in the US is it sold? I only see the EU distributors come up when I Google it.

It used to cool down real quick
Polished Aluminium is the way to go for excellent emissivity.
Not seen any actual dealers in the US for the Giro III,must be one somewhere I suppose.

BTW, I think Teton is more KIA than MIA. Mark is thinking about his next steps, last I heard.

I bought an extra adapter so that the mount can use any of my three tripods including a Celestron with 2" SS legs, a Vixen HAL 130 and an older Meade Standard Field tripod.
I also expect the Unistar will easily carry my Mewlon 250 since Larry displayed a C14 and a Meade 10 mounted together on his dual head Unistar.

I realize saying SCT may get me ejected from here, since the question is about mounting a "big ol' refractor" but I figured an AT90 on one side gets me a pass.

I guess you can configure it to be AltAz but I would think that's too much work. I would guess the reason the OP would want AltAz would be some kind of quick setup as one of the factors.

Very strong, quite smooth, and much cheaper!
