The three-lens design of the Explore Scientific ED-Apochromats provides everything an amateur astronomer desires - at a reasonable price. The construction with Hoya FCD-1 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.
