The three-lens design of the Explores 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. The 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.
The lenght of the OTA has been optimised to make it possible to attach also focus-critical accessories.
