My just completed Jaegers 6-inch f/10
      #5526987 - 11/18/12 10:39 PM

I bought the lens in August, when they were on sale at the Surplus shed, and I got an email offering me an additional 30% off anything in the store. I had also just sold something on eBay for more than I thought I would possibly get. I couldn't pass it up.

I immediately ordered a cell and focuser from Crawford Machine (Crowmach). I had read very good things about Dan from posts here on CN. I don't know of anyone else doing custom work like he does. It took longer than either of us thought it would, but it was more than worth the wait. The cost was more than reasonable, and they are built very solidly.

I got the tube and dew shield from Hastings Pipe, another place that was a pleasure to deal with. Very friendly and helpful.

I had the tube, shield, and a couple of parts powder-coated by a local company here in southwestern Wisconsin.

I'll post photos in the order I took them, as the process went on.

Here's the jig I made for my router to make circles. I used it to cut circles for the cradle, rings for the baffles and for the front of the dew shield. In this photo, you can see a very thin ring that I made to adapt the 8-inch dew shield to the 7.5-inch cell. I decided it was too thin, and just used felt strip.

Here's the handle for the cradle, and an attachment for mounting a guide scope. I made them out of stock aluminum that I had in the garage. I get some kind of satisfaction when I can use what I already have. I made them using a band saw and a belt sander.

Before ordering the tube, I made a 'telescope on a stick'. I put the lens in it to measure just how long the tube needed to be for me to use it with my eyepieces, diagonals, and cameras. Here's one view.

Here are some of the other parts ready to go. You can see Halloween was approaching.

Here are all the parts laid out after the powder-coating was completed. I covered the tube and shield in paper, then sprayed them inside with flat black paint. This was taken yesterday.

And here's the scope on my Atlas, which is just equal to the strain.

The cap. I made this with the router jig, too, and designed the front end so I could mount the solar filters (visual and photo, with AstroSolar film) that I had made for my 5-inch, f/6.4 refractor.

And the mounted filter.

I'd be grateful for any comments, and welcome questions. And thanks for the comment way up there from rguasto!

Of course, now I have to wait for clear skies to actually test the completed scope out. I mounted the telescope on a stick to just test basic functionality, but without a tube there was little contrast. Still, the views were quite sharp when I aimed the scope at a TV tower about half a mile away. But then I lost the instruction sheet for which way the front element should be place, and got some help earlier today here on CN.
