Large viewfinder / refractorwith a 50 mm objective diameter and 242 mm focal length, equipped with an excellent lens made of low-dispersion FPL53 glass. It can be easily attached to a larger telescope's finder bracket and used as a finder,finder scopeor even as a wide-angle telescope for astrophotography or direct observation with an extremely wide field of view.

Application:

• high-quality astrophotography guide scope – with an autoguider, suitable for controlling telescopes with a focal length of up to 1000 mm
• high-quality finder scope that allows direct locating and identification of nebular objects (when equipped with a crosshair eyepiece)
• as an astrophotography refractor intended for use with cameras having small sensors. "EvoGuide" ensures short exposure time thanks to the f/4.8 aperture, works excellently with sensors smaller than 15 mm.
• a convenient wide-angle refractor – standard 1.25-inch eyepieces are sufficient to obtain wide-angle images, for example, a "Plossl" eyepiece with a focal length of 32 mm will provide a 6.6-degree field of view

Features:

• Excellent chromatic aberration correction thanks to the two-element ED glass lens FPL-53
• 1.25-inch helical focuser with eyepiece holder and T-2 thread
• Standard 20 mm back focus, when the back focus extension is removed up to 60 mm, sufficient for use with SLR cameras
• finder bracket with 6 positioning screws
• This telescope, weighing 800 grams, is slightly heavier than a standard finder scope and does not cause a significant shift in the center of gravity.
• The 1.25-inch parfocal ring allows setting a similar focus point for the eyepiece and the autoguider, helping to find and focus a suitable guide star.
• two mounting standards: finder shoe ("Vixen") and a "Vixen" standard dovetail bar.
