Description

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.
