Add my vote for the EQ-6 as an axcellent value. But if that's still over your budget, another good value is the Meade LXD-75 audtostar plus 8" Schmidt-Newt....
Thanks for all of the great advice. First, a correction. My mount is actually a CG-4. I was evidently not thinking when I made my initial post, or I was just...
I had a Meade 6" SN, not the lens mirror combo, just the Newtonian. I got a Skywatcher 8" Newtonian with mount because it was cheaper then getting the 8" Meade...
The first two are Chinese and probably have similar quality optics. I am not familiar with the third scope. "My advice is free and worth every penny!" ...
Thanks for the advice - think Saxon is same as Skywatcher. Have a little reflector at the moment, which is great fun (see new photo in "Rob's Album"). I'm...

That's a stumper. It seems to have a very large eye lens and doesn't look like a typical Edmund Kellner or RKE from that era. An uneducated hunch is that it...
It's a Kellner. I've owned a couple of them. Doesn't have a field stop, so it's really kind of hard to tell what the AFOV is. Lot's of pincushion, so...
Eyepiece is an Edmund 1.25 -1"FL Kellner , it has uncoated cemented lens and an anodized alloy body with no markings and no field stop . It has an ultrawide...

Hi all. I've got a Meade StarFinder mount that I want to change over from AC to DC. This is the AC mount that came with the 6,8,and 10 inch units. Any body...

The easiest and most painless solution is to get a small 12VDC to 110VAC inverter. The kind designed to power laptops and stuff. About a $50 device. There...

Thanks Christopher, I actually have both of these references, and I've tried over the years to match what I read there and simulated with what I'm seeing. ...
I might suggest trying different eyepieces too. I have found it much more difficult doing star tests using Naglers and Radians than when using Orthos. I am...
