I love the winch and the blue string! (For elevation/ALT control?)

Looks like what I'd call a B&Q scope!

Hi Victor --Droid --Ravenous---starwrangler-

my scope with two 635mm mirrors is called "Hexy" (the tubes are 16 sided=Hexadecagon shapes ) -it is F4.7--has fourteen, motors to control all aspects of Hexy's movement's ,pushbutton control box in eyepiece area , it has motorised sliding focusers/diagonal's ,-both tubes are pivoted to swing in 90 degree opposing direction,s to allow merging at the eyepiece,s
.
The alt/az is controlled by motors and special setting circles --the colour scheme is Black blue & Gold
(martian skies blue)
Have melted and polished my own mirror's The whole shebang including the aluminised mirrors has cost Ł1500.00.
Hexy is roughly equivalent to a 36 inch mirror due to the binocular format .
Collimation is a snip=very easy.
this is an old pic. but the eyepiece/ tertiaries are where the 50mm tube is coming out of the cages . Hexy is so well balanced on big bearings-I can literally move Her round and up and down with one finger .
Hope you all like her.

Jim, nice scope , I still ,sometimes ,wonder at the fact that such a large scope is considered transportable , only a genration ago such a thing would have been impossible.

Wow!! superb scope builds everyone.

Here's my my build using a Carton 100mm f/13 lens.
Scope parts are made from M.D.F. board and plastic soil pipe.

Nice scope Rutilus love the cage that holds the scope.
How does the Carton lens perform?

Andy - Since building and testing the Carton, I've found it to be a superb lens.

Racking both sides of focus I get a near identical star pattern with just the very
slighest hint of over-correction.
In focus, I get a tiny trace of C.A. on stars such as Vega and Sirius. Since the start of this year,
I've been able to observe Sirius B four times now, with Sirius being only 18 degrees altitude, the
amount of C.A. around the star is extremely tiny.

I did side by side testing with my Takahashi TSA-102 and a friends excellent FS-102.
With Jupiter I could not see a difference between all three scopes in terms of the planetary detail
observed. The Carton showed the festoons, great red spot, oval BA and rifts in the belts, every bit
as good as the Tak scopes.

The Carton is a fantastic double-star scope, again being the equal of the Tak's. I actually found
the F star in the Trapezium easier to see with the Carton.

The sharpness and contrast of the lens is excellent, with the albedo features and 4 to 5 bright craterlet
markings being easily visible within the Lunar crater Plato. On the night of a recent Full moon, I could
easily see different colouration hue's on the lunar surface.

I have been so pleased by this scope, that I have now sold my TSA-102, and used to the money to
fund the building of a Istar 6" f/15.

Here's a picture of the M.D.F. lens cell.

Hi!
There is all my home made equipment: 8" F/15 classical cassegrain, the 70 F/4 RFT ("The Steam Locomotive") and the Fraunhofer refractor 80mm F/11.25 and 6x30 finder, all suported by the heavy piston AZ mount on a cherry wooden tripod:

The optical elements are not my work,they are bought new or second hand. The details of constructions are presented on my threads.
