High-quality apochromat with special glass
Explore Scientific’s Essential series features a three-lens ED apochromat with special glass for expert-level results at a moderate price. The three-lens construction with Hoya FCD01-ED (extra-low dispersion) special glass and two air gaps significantly reduces chromatic aberration. You get bright and sharp images of deep sky objects with fine details. This powerful telescope is also suitable for travel and is the perfect companion for astrophotography applications.
This apochromat has everything required to make any astrophotographer’s heart race – and for a reasonable price.
The three-element construction from special FCD-1-ED glass by Hoya, Japan, and two air gaps create a corrector which is considerably higher quality than two-element ED apochromats available in this price range. A calculated polystrehl value of over 0.9 produces a much clearer image than the 0.8 which can be obtained using two lenses. This outstanding image performance, combined with a sturdy mechanism, creates a package which leaves nothing to be desired.
An optional field flattener accessory for photography is also available – this means the instrument can be used for photography with no restrictions. The tube length has been optimised so that accessories with critical focal positions can also be used.
