That's why I did it, black shrouds were too boring and generic for me. The orange shroud does have a black liner however. I also think that being a double layer shroud, it probably keeps moisture out even better.

I can see it now, some one at a star party asks you which one is yours, and you reply, the one over there glowing in the sun. :roflmao: :roflmao:

Mines just plain, boring, black. lol

It does make finding my way back to my stuff on a crowded field a little easier!

My 4" F-15 Jaegers lens.. Nothing too out of the ordinary.
I made the lens cell, end cell, finder (old Edmund lens) and baffles. Lens is superb, really one of my favorites.

@Bremms, do you use one of the lenses from SShed? Is it coated?

I did. all the machining other than the GSO focuser. The lens cell is just bolted flat to the flange. The end of the tube is square and the lens is perfectly collimated withou adjustment. Working on a Jaegers 6" F10, but haven't started making parts. Did get the aluminum for the front cell.

Excellent workmanship, Marc. Funny how doing your own machining means perfect alignment, eh?

How are you going to paint them?

Might leave the tube bare. I was going to try and anodize the the cells but the lens cell is 7075 and 7075 does not anodize really well. Bare it is for now, I have a couple tubes that might get powder coated.

I like how OSH semi gloss black rattle paint comes out with a coat of etching primer under it:

Among other scopes I've built, this is the latest; a satellite tracking radio telescope.... Capable of transmit mode too.

Hi Bob, there are four 50-foot cables; 12VDC power cable, a control cable to stop/start/reverse the step motor for ascending or descending orbits, and, two antenna cables for the UHF/VHF sections, that will tie the Kenwood TS-2000X transceiver to the tracking antenna mount.

Best,
Steven

Ok, I was keeping this on the low-down.... At the star party I host yearly for friends I always find cool things to do. http://darkskyobserving.com/OSP.html
Check out OSP IX for 2013 and the other links for previous years....

Four weeks ago to the day I posted the small Dob project I'm working on. It's on page 7, about 1/3 of the way down. Originally I was going to make it one piece but decided to make it a split assembly, along with a few tweaks I made along the way. There's still quite a bit of work left to do, but it's coming along nicely.

Beautiful wood working, did you split it due to a long focal length, or just to make it easier to handle?.

Thanks for the compliment on my woodworking. I'm actually trying out a lot of ideas with the ultimate goal of one day making a 10" or 12" Dob for dark sky using this design. One of my goals is to see how inexpensive I can make it. Almost everything was fabricated from scraps or was in my miscellaneous hardware containers.

Speaking of building a Dob on the cheap, I was walking my Labrador Retriever and saw some beautiful plywood in the dumpster in front of a fire damaged home. I asked the contractor and he said that someone had dumped the wood in his trash container and I could have it. It's gorgeous 13 ply furniture grade stuff that I can make the wood parts for the 12" Dob. How cool is that!
