Every week I do something new to reduce light pollution. Eyes on the Sky is at 650,000+ views so far; more views = more awareness. Please consider sharing with others.

Quote:Do you have the hydraulic lift to reach the eyepiece yet?
Quote:Congratulations Sean, and best of luck on the project. My 16" f/7 can see first light any night now, depending upon whether or not I want to wait for a bracket for my ServoCAT control box. My feeling is that such a scope deserves better than duct tape for it's maiden voyage.The fact that northern Arizona temperatures are getting into mid-teens has nothing to do with my delays I thought about an equatorial platform for mine. I have first-hand experience with the Osypowski platform and nothing but good things to say about them. But given the scale of my project ServoCAT seemed like a better choice. And GOTO will be very handy with 2800 mm focal length. Driving the whole thing wirelessly with SkySafari and an iPad was icing on the cake.
Quote:Jeff, simply beautiful! The split truss is the way to go for resistance to misalignment. It should be an awesome all-purpose telescope. Do you have a 3 or a 4 wave spider. A 3-vane is better diffraction-wise. How big is your central obstruction?Mladen

Hypotheses non fingo
Quote:So I know that I like to have a very quick setup. I don't like fiddling with lots of pieces. When my scope breaks down, it has to break down into 3 or four manageable parts.
Quote:Yea both you and Napersky (Mark) got a major package yesterday. That explains the week of clouds we have coming. Thanks a lot. lol.
Living at a dark site, I make scope when I have the inclination. I also do woodworking, cycling and other outdoor activities
A 60mm department store refractor started it all....
Quote:> I would say four vanes is somewhat better diffraction-wise.If all vanes are the same size, there will be less light in the six spikes produced by the three vane spider than in the four spikes of a four-vane spider.
