|Altair Astro 10 inch F8 Ritchey Chretien Carbon Fibre Astrograph telescope.|
10 inch F8 Ritchey Chretien reflector telescope, primary and secondary mirrors are of fuzzed quartz which reduce coma and optical aberration (which gives pin point stars to the edge of view)so hardly any expansion in any temperatures, the mirrors are also coated with silicon dioxide for extra protection, carbon fibre tube for a light weight telescope (with the Crayford focaser 15kg) , with baffles down the tube to eliminate stray light, 75mm Losmandy dovetail plates help to stabilise the tube from flexing (which is common in CST telescopes), 2 inch crayford dual speed linear focuser, which is very smooth in operation, there are 3 small fans at the rear of the telescope, these aid in fast cool down of the main mirror in warm weather, there are 3 extention tubes one x 50mm and 2 x 25mm, these are for focusing the telescope, and go between the scope and the linear focuser, they give you lots of back focus for cameras with filter wheels, all in all a fantastic telescope extras which are in with the sale are 2" Di Electric Diagonal and 9 x 50 spotting scope.
would like the buyer to pick up the scope, but will send by Currier at buyers expense.
