The optics in the AP 72/420 telescope use a doublet lens with one lens element made from a particularly low-refractive index ED glass. High quality Schott glass is used for the crown glass element. Each glass-air surface in the optics is provided with a metallic anti-reflection coating for achieving an outstanding maximum light transmission of 99.5%! This optical design of the apochromat ensures an absolute minimum of chromatic aberration and provides a very sharp image!
This affordable, short focal length refractor is ideal for the astrophotography of large star fields without the need for a heavy duty astronomical mount. It is also ideal for when traveling or for portable astrophotography in general. The sensitive focuser with a 1:11 reduction gearing is a great help when focusing.
This telescope is designed as an astrograph, that is, the focal position is designed for astrophotography.
