I am looking to mount a Lunt Ls90 on my CPC800 in the future. The total piggyback weight that I am looking at would not exceed 12 pounds. Has anyone ever tried this much weight on a CPC800? And if so, how did it work. I would really like to try this solar scope but I do not want to invest in another mount for it. Thank You, Post Extras:       A.

[Re: Larry Hansen]       #5644510 - 01/26/13 02:33 PM Edit   Reply   Quote Quick Reply   Hi Larry, I have mounted a C80ED and imaging camera with 6 lbs of scopestuff weights on a bottom rail. I estimate that is about 14-15 lbs including camera and/or 2" eyepieces. In Alt-Az I have found this combination to be problematic. With poor tracking, yet I believe this is due primarily to improper balance. I find it very difficult to achieve proper balance as the weights I have do not protrude far enough to offset the refractor. I have since removed the C80ED and i now use a PST on top with about 3 lbs of weights on the bottom rail and find tracking to not be impacted at all. I have read of other users in fact running with much more than 10-15lbs of weight but i suspect they have very good balance. For me, with the first combination I could balance maybe in 30-70 degree in elevation, but at 90 or 0 degrees it was unbalanced. Perhaps on a wedge the balancing issues would be easier??

Pier mounted on a wedge. With the exception of the bike, the boats and the car in my signature most of it lives on the scope! Post Extras:       Pages: 1
