I saw a Webster D14 with 14.5 inch f/4.3 Zambuto mirror, Argo Navis, 10K encoders, and ServoCAT. The price was a little more than I wanted to pay. I waited a week and it moved to I price I could love. Yesterday I drove 4 hours to inspect and buy scope and another 4 hours home. Last nights first viewing had a lot of little issues, such as lousy balance, sticking ServerCAT in azimuth and to slippery of motion.
I spent about 8 hours today making little improvements and now the scope is working great. It was way light in the UTA so I added 2 boards to the UTA, one for the Telrad and another for a Stellervue 60mm finder. The balance is now perfect. I used a Powermate 2x plus my ES 25mm 100 AFOV as the heavy test. The Powermate is a proxy for the ParaCorr 2 that I ordered. I also put a Naglar 5mm T6 as the light test. The scope stays in place with the heaviest eyepiece combos and also with no eyepiece at all.
I removed a lot of excess Turtle wax and the movements are much better. I put a 20mm rubber rim arround the ground board and the azimuth works great without sticking. The previous owner used it in some heavy grass and it stay stuck on the board and leave some groves that caused the sticking. The rubber rim resolved the issue. I built a platform out of plywood and 4x4 wood in each corner. This gets the ground board out of the grass and improves the hight for viewing. The scope was a little low for me directly on the ground. The focal length of the scope is 62.7 inches according the the mark on the Zambuto mirror.
I spend about a 1/2 hour on the moon this early evening after collimating to check out my improvements. I am content with my work and very happy with the purchase. I am now awaiting enough darkness for alignment stars.
I previously was considering buying an 18 inch dob new but decided to save myself 5-9K$ by downsizing to the 14.5 inch instead of a new 18 inch dob. I have access to our clubs 20 and 24 inch Dobs whenever I feel like dealing with a big, heavy and ladder encumbered dob. The D14 fits in my car better, is much easier to push up the ramp and is a much safer scope height wise for public outreach. The ServoCAT will free me up from nudging the scope so I can tend to my TEC 140 when doing 2 scope public outreach.
