Product Highlights

- 50,8mm Crayford focuser with micrometric knob

- Support rings and Vixen style dovetail bar

The optics AP 72/420 contains a Doublet lens with a lens made of particularly low-refractive ED glass. For the Kronglas element high-quality Schott glass is used. Each glass-air surface of the optics is provided with a metallic anti-reflection coating to achieve a high, maximum light transmission of 99.5%! This optical construction of the apochromat ensures a very strong reduction of color aberration and a very sharp image!

This affordable, short-refracting refractor is ideal for astrophotography of large star fields without the need for a large astronomical mount. It is also ideal for traveling or in general mobile astrophotography. The fine - focus focuser with a 1:11 reduction is a great help in focusing.
