How about another one?

Posted By David Williams
This was the second scope I built last year using the same optics. The first was tooo heavy for my taste. 10" F5 on a University Optics cell. It is Carbon Fiber with quick release truss connectors and adjustable CG. Its big brother is 75% done. It will be a Carbon Fiber and aluminum Obsession type using a 16" Nova mirror.I have some in process photos of it if anyone is interested.

First generation and next

Here is a photo of the first round of 10" F5 with the Carbon next generation and mold during construction

Carbon 16" in process

Posted By David Williams
I wanted to buy a flotation cell but between the pricesand delivery times I decided to do my own.

What is standard?

Posted By David Williams
The 16" F5 I am building will be ready for the pole cutting procedure in the near future. Anybody got any suggestions as to the best eyepiece to use as a center of travel standard? I have one of the JMI units that doesn't move all that much so I need to get this one as close to perfect as I can. In the past I always used my standard starting eyepiece a 2" 32mm Meade UW. I don't want to end up with short poles when my eyepiece collection changes.

Sneekin' up on first light.............

This project has been in the works since late fall 2002. Am I slow or what? I started with the mirror cell and then made the mold for the box. The box was made around the end of Dec. 2002. The upper tube rings, focus and finder mounts were next. The upper rings are honeycomb core carbon fiber. The altitude bearings and rocker late in 2003. The time spent creating the molds would have been enough to build a plywood scope. Since I do R&D work on aviation parts it was nice to do something that didn't have .005 tolerences. But then you do it anyway.....

Carbon Cage

Posted By David Williams
My year and a half so far 16" F5 is getting close. I am waiting for a sheet of Kydex to arrive to finish off the secondary cage.

Carbon Mirror box.........

Posted By David Williams
Someone asked about the Moonlight ball mts. Here is a shot of the mirror box and altitude bearing.

Not sure you guys ever saw this one. It was a warm up project before the 16" was started. I always intended to make a carbon and aluminum rocker box but the 16 took over my time and interest.

10 F5 Carbon scope

Posted By David Williams
Per your requests here are the two best feature that I innovated for this design. Ajustable CG and the ajustable length snap off truss tubes. I think this photo shows both features well.

1st setup 16" F5 Carbon scope

Posted By David Williams
Ok, its not as far along as it looks. The optics aren't installed yet and the truss tubes aren't cut yet. With tubes this long it would have to be a F8 or so. But I just had to roll it out. 8)
