Ceravolo HD 145 Maksutov Newtonian Telescope with rings, case, dew shield. This is a rare scope with premium optics. It will give stunning views of the deep sky with a flat FOV as well as high mag views of solar system objects. It has a very small central obstruction, and it will give 140mm apos a run for the money--at a far lower cost. The scope comes with a 2" helical focuser and 1.25" adapter, dew shield, heavy rotrating rings and Losmandy 18" D plate. A Rigel is included as well as a metal objective cover and fancy shower cap. I have a sturdy, but heavy, professional case for shipping. The scope weighs about 25# with the rings attached. I recommend a G-11 class mount, although the scope can be used as a dob with the rings removed. It is in excellient condition with a few scruffs on the shiny tube and perhaps a few small sleeks on the corrector. Collimation is dead on and does not need regular adjusting.

This new design with only 15% C.O. is a visual superkiller scope. Doing an startest the central obstruction looks not more than an thinny central zone you see sometimes in high quality refractors. Its nearly impossible to see more energy in the first diffraction rings, than in an nonobstructed refractor. This new design should be the nearest possible matching design of any telescope against high quality colorfree apochromatic refractors.

I have a great example of a 1962 Questar Standard 3.5 upgraded scope. The scope had a Questar service in late 2017 and everything is buttery smooth. The service included: standard service, upgrade to Powerguide 3 (which I have never used), upgraded manuals, Questar screw in eyepiece adapter along with two 16 and 24mm Questar screw in Brandon eyepieces, and a shipping drum. The dew shield is a pretty purple with just a few small marks and is in really good condition. The front cover is made of synthane. The deluxe leather case is in very good condition but has a few scratches (which do not show up in the picture) which I had a professional leather company smooth out and blend. Other items that go with the scope are a weather resistant document pouch with zipper and a library bound 6-month issue of Sky and Telescope circa 1962 in great condition to experience times of yesteryear. Serial #: 2-1342 Born on Date: 7-6-1962 Mirrors: Pyrex Coating: Broadband Multicoating

What some consider the "sweet spot" classic period of Questar design, this example was produced in 1964 (#4-2141). The kit appears to be fully correct for the period, with correct badging and the small and stout rear axial port plug. Absent are an original lens cap (a threaded metal one is provided) and the finder solar filter, which is believed not to have been provided and is available from the factory as an easy add-on. Off axis solar filter is present as is stop-down ring (Caution: having a solar filter without a finder filter is risky if careless or uniformed users will have access to the scope). Both eyepieces are present and in excellent condition. Legs and original AC cord are included. The moon map and dew shield are the ideal purple color of this era. The dew shield has some minor scratches that are not apparent except under great scrutiny. The photographs give the correct impression. The polished surfaces are bright, with several minor scratches on the base flange that are depicted. The handsome original English leather case shows significant wear at the hinge and some edges, and some separation at the upper edge of the hinge. The handle is solid, and the case appears trustworthy for carrying, even as it may be fragile for more demanding transport needs. The optics are superlative, meeting typical Questar standards. The mirror and corrector have been recoated in 2020 by Cumberland (Questar’s long-time optics supplier). Star tests presently display a beautiful Airy disc, and the scope also performs beautifully on terrestrial, lunar, planetary and nebular subjects. All mechanical and electrical actions operate smoothly and properly, and the finder is collimated and focus shift appears within Questar specs.
