Bresser EXPLORE SCIENTIFIC ED APO 102mm f/7 FCD-1 Alu 2 R&P Focuser

The  three-lens  design of the  EXPLORE SCIENTIFIC ED-Apochromats  provides everything an amateur astronomer desires - at a reasonable price. The construction with  Hoya FCD001 ED glass  has  two air spaces  and provides a level of correction so superior to the two-lens constructions, that are common in this price class, that you will see the difference immediately. 

This excellent optical performance teams up with a high precision mechanics - the result is a telescope on a level that is setting a new standard in it´s price class. Astrophotographers will love this telescope - a  optional field flattner  is available and makes the telescope perfect even for cameras with a large chip format.
