Hi Norm,
Very cool looking scope there! I like the setting circles! I made my setting circles from craft disks I found at a Michaels. Unfortunately the hand-drawn division lines didn't some out so well so I'm going to glue CAD drawings on the disks instead...

Cheers
Roger

Roger,

Have you considered using an aluminum yard stick graduated in 1/10th of an inch? Bend it into a circle and each 1/10th inch will equal 1 degree. The diameter will come to 36/Pi=11.46" Cut a wood disk to that outside diameter, and a smaller concentric hole with inside diameter to fit your shafts. The right ascension will equal 1.5 inches per hour and each 1/10th inch will equal 4 minutes. I haven't done this yet, but it seems like it would work.

Tell you about marrying a girl. My first wife hated astronomy, telescopes and all my friends. And then even me.

She took off and I got a divorce. Five years later I met a special girl who was so different. Not trusting my instincts, I taught her telescope making and insisted that she make one.

She did, and I married her two weeks later! Never regretted it in what now is almost 32 years. We married on Valentines Day, and now I have a granddaughter due on that same day -- our first.

Congratulations!!, Ed and Denise!!!....and Happy St. Valentine's Day, too!!!!! ;)

Hi Larry,
Very cool idea if I had a way to make a decent wooden circle I would definitely try it. My mounting also limits me (especially on the RA axis) to 9" in diameter

Hello
This telescopes is a classical Cassegrain, the total weight is only 47.63 pounds, just because I have used carbon fiber with balsa wood and aluminum. I can even reduce 4 pounds the total weight of the telescope, I have used aluminum for the trusses, in a future I would like to use carbon fiber trusses.
The primary mirror is a conical 16” from Royce, it has an Inter-mirror distance of 50.84- inches,
the Secondary is also from Royce with a diameter of 3.60-inches and the Back Focus is 14.5-inches
No floating cell is needed for the conical mirror.

I use a Moonlite dual focuser and the finder is fron celestron.
The mound, is a CPC mount from Celestron, I just have changed the arms, in a future if God wants, I am going to buy a nice mount for my Cassegrin.

OK, here's my homemade scope, a 10" f/4.5 mirror refigured by OWL (And it came out nice). 1.5" RA shaft, 1" Dec shaft. Most everything put together with no more than a drill press excpet for a few parts that I was able to make when I had machining classes year ago. MoonLite focuser, homemade spider diagonal, University Optics Mirror mount, drilled out and fitted with a fan and baffle for thermal eqilibrium. For now a pic of the mount....

Here's my 16" f/4.5. The messy wiring is being taken care of and the shoebox dew shield over the telrad has been upgraded since, I just haven't gotten a more recent picture. :)
