I have a Stellarvue SV102ED2 and I have a Porta Mount, but i'm having trouble in the balance department, so I was a wondering if any one out here has the same trouble. :?: :?: :?:
I don't know if I should get a different mount, I want it on a Alt-az mount, I know I could use my Meade LDX-55, but I don't have a good shot of Polaris, to aline it up for "Go-To.

:thanks:

Tom

Tom,

The Portamount has tension adjustments- have you tried adjusting them? They're accessible with an Allen wrench. I've found that the Vixen Portamount holds a 4" refractor fairly well.

Erik,

I tighten the tension, but I don't want to tighten them too much that I strip the treads, then I'll hve to get another mount.
I also use the mount for my Orion 80mm Express, when I go to one star party where a lot of kids there, so I don't want anything to happen to my SV102ED2.

:thanks:

Tom

In that case, you may have to slide the 4" scope back and forth in the tube rings to adjust the balance, depending on the viewing angle.

Or, you could tighten the tension a bit more and make a counterweight system for the 80mm setup. That way you could use both scopes with the mount. :)

Erik,

I have clamshelles mounting on both telescopes, the SV1102ED2 has a mounting bracket so I can get a little more travel out of that scope.

Right noe the weather is too cold for me, I'll wait until March, and work on the balanceing promblem.

:thanks:


Tom

I use my 4" refractor on a Sky View Pro mount. It's very solid for a 4" but as you know, it's an EQ mount not an Alt-Az. Of course you could set it up in Alt-Az mode. Maybe I'll try that and report back how well it works.

Square_Peg,

I want a Alt-az mount with slo-mo controls.

Thanks,

Tom
