Product Description
Sky-Watcher's EvoGuide 50ED is the ultimate new high quality 50mm doublet ED Guidescope, finder or ultra portable telescope, utilising world class Ohara S-FPL53 glass for the ED element. Corrections are amazing with the use of ED glass, colours are true and contrast is superb. With a focal length of 242mm it has a very fast focal ratio of just f/4.8. The Evoguide is equipped with a fine and precise helical focuser enabling sharp focus to be easily acheived visually or on a camera sensor. It can also be used as a finderscope, or just as a small richfield premium telescope for travelling. Please note it can only be used straight through, a star diagonal cannot be used.
Dovetail bar & Finder stalk
The Evoguide-50ED is now supplied with a standard Vixen type 45mm dovetail bar for telescope mounting, a 1/4-20 thread for tripod mounting and a finderscope dovetail bracket for mounting onto a standard finderscope shoe
Optical Advantage
The use of genuine Japanese OharaS-FPL53 glass not only provides superb colour correction and contrast visually but is beneficial to auto-guiding, stars that are better corrected are smaller and better resolved so take up less pixels on the sensor for more accurate guiding during long exposure imaging.
