Thoughts on a Celestron Advanced VX 8" Newt
Posted 10 February 2013 - 12:58 PM
Figured if I don't use it or don't care for it a 8" newt OTA isn't the worst thing to try to offload on the used market. Probably wouldn't get 300 for it, but I'd be ok with that.
I don't have a newt yet and I think there is some rule about owning one of each type of scope.
There is a 6" newt for only 100 more than the mount but it only has a 1.25 focuser and a single counter weight. I have several 2" eyepieces (if I used it for visual at all) and I was probably going to buy another counterweight anyways. And I probably could offload a 6" newt for $100.
Feel like I should just buy the Advanced VX mount by itself but what is the rest of the tax refund going to do, earn .01% interest?
The 6" refractor is also there at only 500 more than the mount alone. I already own a little 80mm refractor but don't use it that often, just piggyback it onto the CPC here and there.
What would you do?

Regarding quality of the OTA: I have the C8-NGT which appears the be the same OTA as the VX 8" newt. (i think they just updated the mount?)
Here's a sample image taken with my Celestron 8" newt: (but riding on a CGEM DX mount)
Vignetting is pretty strong at the edges of APS-C size sensor, but good flats will correct the problem. Otherwise I'd say it's a good OTA for imaging.
