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 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.
Features:
- Three lens air-spaced ED-apochromat
- Hoya FCD01-ED glass
- Polystrehl of above 0.9
- Backfocus: 165mm above 2" adaptor
The kit includes:
- Optics with dovetail plate and finder slot
- 2" Star Diagonal 99% reflectivity
- Dust caps for front-lens and focuser
