I *think* I'd like an eq mount since that will make it a little easier to share my viewing enjoyment with others who have less practice tracking targets manually, but I also like doing some terrestrial viewing and I might try some starhopping which would seem to be easier with an alt az mount.
I know for some eqs it's possible to use them in alt-az mode by tilting the polar axis up to 90, but I understand the cg-4 is not meant to be used this way and the polar axis doesn't go past 60. What I'm wondering is:
1) Is there a similarly priced eq mount that would work in alt-az?
2) Has anyone tried modifying a cg-4 to use in this fashion
3) Failing options 1 and 2, is there an alt-az mount with slow motion controls available for a reasonable price? Would the Celestron #93607 (I've seen it described as "medium-duty Alt-az mount" and as "heavy-duty alt-az tripod" but I think they are the same thing) be suitable? Is that mount still being made? It was not easy to find on celestron's website. I had to search for it by product number. It didn't show up in the products menu. I appreciate any info anyone's got to share. Thanks!

As I understand it you can set the latitude for 90 degrees on an EQ mount and it then acts like an alt/az. Don T.

I suggest to go with a proper CG5 class mount. I remember I was comparing them at some point and CG4 was inferior to CG5 in many respects.
You would be surprised of how cheap you can get CG5 class mount. Some examples:
-couple of weeks back there was an older Great Polaris mount on S&S for 160
-LXD75 or CG5 Goto are often sold for ~300 on S&S
-Meade has refurbished LXD75 for 475
-there are generic versions of CG5 available for around $230 new

Avarakin - I've heard of that generic cg5 mount. Where would one look for it?

I am not seeing them sold separately nowadays, but I see it is sold with an 8" scope:
I have no idea how good or bad this scope is. Maybe you need to talk to vendor about getting mount only.
I think your best bet would be to give an ad on S&S - "WTB CG5 class mount" and wait till someone replies, maybe you will have to bump it couple of times.
