Some more in depth detail about the main components of Alan

  • Telescope

    Officina Stellare Veloce RH 250 10" F/3
    • Aperture: 250mm (10'')
    • Focal ratio: F/3
    • Focal length: 750mm (30'')
    • Linear obstruction:55%

    The RH Veloce is a really unique design, and uses several unique solutions, created by Riccardi and Honders (from this the "RH" in the name).  You can now expect an even better large field photographic performance thanks to an innovative light baffles coating will give you a much better reduction of ghosts and scattered light. Provided with FF72 focuser, FFC focus controller optional. From the advanced astrophotographer to the professional, Veloce RH250  Series is the answer to every need.

    The Officina Stellare Veloce RH 250 (Riccardi-Honders) Astrograph offers a fast f/3 focal ratio combined with a very high image definition over the whole corrected field. Veloce in Italian means fast, to indicate its primary vocation: to be a great astrograph capable of stunning performance. It has 250mm of clear aperture and a focal length of 750mm.

  • Focuser / Rotator

    Gemini Focusing Rotator
    Optec engineers have developed a completely new concept for combining telescope focus and camera rotation functions into a single robust, yet compact package.  Rather than simply adding a rotator onto the end of a focuser drawtube, Gemini was designed from inception with a rotating drawtube providing superior strength and rigidity for heavy camera payloads.  Featuring four lead-screws and four linear bearings, Gemini can easily handle 10-kg. (22-lbs.) payload packages without flexure.  Full 360-degree rotation is a built-in function of the Gemini with a full 1/2" of linear travel.  At the center of travel, Gemini measures a mere 2.45" in thickness. 

    To maintain a flat, rigid base for heavy camera packages, Gemini's shell consists of two parallel plates machined from MIC-6 tool plate providing flatness within 0.001" (25 microns).  Seven precise stand-off spacers maintain the 2.2" separation of these plates.  The rotating drawtube is moved linearly with 1/2" of total travel using a premium timing belt driven by a high torque stepper motor.  The entire package is accented with a beautiful carbon fiber wrap.  Dual RJ45 connectors provide connection to the Gemini Control hub.  The independent rotating drawtube is supported by a custom X-cage bearing system supported by large, 6mm chrome ball bearings.

Who is Alan Shepard?

Rear Admiral Alan Bartlett Shepard Jr. (November 18, 1923 – July 21, 1998) was an American astronaut, naval aviator, test pilot, and businessman.

A graduate of the United States Naval Academy at Annapolis, Shepard saw action with the surface navy during World War II. He became a naval aviator in 1946, and a test pilot in 1950. He was selected as one of the original NASA Mercury Seven astronauts in 1959, and in May 1961 he made the first manned Project Mercury flight, MR-3, in a spacecraft he named Freedom 7. His craft entered space, but did not achieve orbit. He became the second person, and the first American, to travel into space, and the first person to manually control the orientation of his spacecraft. In the final stages of Project Mercury, Shepard was scheduled to pilot the Mercury-Atlas 10 (MA-10), which was planned as a three-day mission. He named Mercury Spacecraft 15B Freedom 7 II in honor of his first spacecraft, but the mission was cancelled.

Shepard was designated as the commander of the first manned Project Gemini mission, but was grounded in 1963 due to Ménière's disease, an inner-ear ailment that caused episodes of extreme dizziness and nausea. This was surgically corrected in 1969, and in 1971, Shepard commanded the Apollo 14 mission, piloting the Apollo Lunar Module Antares to the most accurate landing of the Apollo missions. At age 47, he became the fifth and oldest person to walk on the Moon, and the only one of the Mercury Seven astronauts to do so. During the mission, he hit two golf balls on the lunar surface. He was Chief of the Astronaut Office from November 1963 to July 1969 (the approximate period of his grounding), and from June 1971 until his retirement from the United States Navy and NASA on August 1, 1974. He was promoted to rear admiral on August 25, 1971, the first astronaut to reach that rank.
