The powerful parabolic Newtonian Explorer 150 P is a very good telescope for the advanced beginner and also a transportable second telescope. 150mm aperture gather 450x more light than the naked human eye. Faint galaxies and nebulae become visible! The diffraction-limited precise main mirror is also a good choice for successful lunar and planetary observations. Due to the reflective optics priciple, the images are free from false colour and full of contrast. The 2" Crayford focuser allows using 2" eyepieces and also coma correctors for photography. With the standard 1.25" adapter, normal eyepieces can of course also be used.
