I particularly like this clock-driven and/or even slow motion equatorial arrangement for mounting a pair of 10x50s binoculars. It's a very steady and rigid way to enjoy binocular observing if you want to spend time viewing an object for an extended period of time while tracking on it too..,.> http://i.picasion.com/pic82/aeb620f0bfc1caf2dfb70cb4b442b87b.gif Klitwo

Thanks for the kind words. It was basically all hand-made out of 1/4-inch plywood with some 1/2-inch plywood thrown in places for good measure.....Strictly made in the same tradition as Sir Isaac Newton hand-crafted his splendid wooden Newtonian telescopes. All of the plywood was cut by hand...same with any drilled holes with the use of a non-electric hand drill. Lots of wood glue, hand sanding and some redwood stain. I hand-ground and polished the 10-inch f/4 Pyrex mirror back in the early 1960s and still found use for it in my Dob-Buster (See 4th. image)....All-in-all it was about 12 month project. Note that the four brass knobs on the top four corners of the primary mirror's optical box (3 brass knobs for collimating and the 4th for locking the primary mirror in place once collimated via black O-rings and small hand-made wooden pulleys - See 3rd. image). Collimation of the primary mirror is accomplished by adjusting the three brass knobs in a sequence while looking through the 2-inch PVC eyepiece holder with the eyepiece removed. How does a sled focuser work? that's cool as heck! Because you kindly asked....> The low profile two-speed horizontal lead screw sled focuser carries a secondary mirror and it's PVC secondary mirror holder on a single 1/8-inch dia. 6-inch long stainless steel strut that is attached by a threaded insert into the bottom of the wooden sled (slide). Simply said...The secondary mirror and it's holder moves horizontally via the 2-speed horizontal threaded (coarse/fine) two-speed lead screw....forward or backward along the primary mirror's optical axis (cone of light) for focusing the 2-inch Erfle eyepiece....See 2nd. image.

My homemade periscope-style off-set magnetic base all-plywood 40mm finder I use on my homemade all-plywood 10-inch f/4 Dob-Buster. P.S. The image also shows my all-plywood horizontal lead screw (two speed) sled focuser with my homemade 2-inch PVC 32mm 5-element Erfle eyepiece. Klitwo

1st. Class Image...Excellent! Klitwo

Splendid 1st. image.....Next stop is the Horse Head! Klitwo

Excellent! Splendid looking setup. Klitwo

For those interested....these are some "big" binos....> Even before I completed my dual 6-inch f/15 Dall-Kirkham clock driven Cassegrain binos in 1980.....these big dual 1.2M Cassegrain binos were in operation at the AMOS Observatory (10,023ft. elev.) on top of Haleakala on Maui in Hawaii. Little did I know in 1980 after completing my own ATM bino project that a short time later starting in the early 80s I would be operating and help maintaining them for AVCO Everett Research Laboratory and the U.S. Air Force at the AMOS Observatory on Haleakala on Maui myself. (wikipedia.org Public Domain images)....> https://upload.wikimedia.org/wikipedia/commons/4/49/AEOS_MSSS_GEODSS.jpg The 1.2M Binos are housed in the large white lower left observatory dome in the bottom AMOS Observatory image. Most of my assigned astronomical duties and engineering projects were in the two large white AMOS Observatory domes (upper middle large white AMOS Observatory dome housed a 1.6M telescope) in the bottom image. The large silver metallic observatory dome houses a 3.67-meter telescope, known as the Advanced Electro-Optical System (AEOS), owned by the Department of Defense, is the United States' largest optical telescope designed for tracking satellites.

They do good work on restoring and servicing modern and historical binoculars....and are highly recommended....> http://opticalrepairs.com/ Klitwo

Nice binoviewer set up on your FS128 you got there..... I went the cheap route with my homemade 1980 6-inch f/15 Dall-Kirkham Cassegrain bino. Used a pair of 1979 7-21x Bushnell small lever "zoom" eyepieces with a mechanical IPD adjustment knob under the black box. The aluminum vertical action focusing knob is visible in the 1st. pic.

I'm sure that Mr. Damian Peach's astro-images have circulated around the Stargazers Lounge website and various public media before....but it's always nice to once again show his splendid astro-images to those (first-timers) and others who are less experienced and are also striving for perfection in thier astro-imaging efforts too....> http://www.damianpeach.com/ Klitwo

That cute little Fox ? sitting on your observatory fence is probably waiting patiently to see the results of your astro-imaging session....and in particular....IC405! P.S. This appears to be a rare event. Not often one sees a little Fox ? so interested in astro-imaging. Klitwo

Waiting for sunset at the 2011 RTMC Expo at Camp Oakes in Big Bear, California with my homemade Nexstar 4SE powered (40K object database) dual 102mm f/6 Celestron GOTO Binoscope..... (2011 RTMC EXPO Warren Estes Memorial Award)
