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.
