The Sky-Watcher EXPLORER-150PL is a fantastic choice for intermediate astronomers and also the serious beginner. Has a large 150mm of light gathering aperture combined with superb parabolic optics. With a longer focal length of f/8 this telescope provides higher magnification with a given eyepiece than its f/5 cousin, the Explorer-150P. Delivers excellent performance for the observation of the Moon, planets, nebulae, galaxies, star clusters and tight double-stars.

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.

Item condition: used Item with possible small cosmetic deffect, but every function works perfect
