Explore Scientific's ED APO 127mm f/7.5 FCD-1 Alu 2'' R&P Focuser is a high-quality telescope with advanced optical and mechanical features, suitable for amateur astronomers and astrophotographers.
It incorporates a three-lens air-spaced ED-apochromat design with Hoya FCD001 ED glass. The air spaces in the construction offer superior correction compared to traditional two-lens setups, providing sharp and clear views of celestial objects. This level of performance is not typical in this price class, ensuring users can see the difference immediately.
The telescope is paired with a precision focuser offering 10:1 reduction for fine-tuned adjustments. This, coupled with the included tube rings and handle with a camera mount point, makes it versatile for astrophotography. Additionally, the 2'' star diagonal, with 99% reflectivity, enhances light transmission, delivering clear and bright images.
Explore Scientific offers the telescope in three different product lines:
-
Essential Line: Featuring Hoya FCD-1 glass lens, aluminum tube, a 2.0'' rack & pinion focuser with 1:10 reduction, and a 2.0'' star diagonal with 99% reflectivity.
