A small refractor with a 50 mm lens diameter and 242 mm focal length, equipped with an excellent lens built using low-dispersion FPL53 type glass. This telescope can be easily mounted to the finder foot of a larger telescope, it can be used as a finder, guider, as a wide-angle telescope for photographing the sky or direct observation in an extremely wide field of view.
Application • High quality astrophotography guider - equipped with autoguider it is suitable for telescopes with apertures up to 10 inches • High quality finder that allows direct discovery and identification of nebular objects (after being equipped with an eyepiece with a cross) • As an astrophotographic refractor for use with cameras with a small sensor. The refractor ensures short exposure times thanks to f / 4.8 light, it works great with sensors below 15 mm • Convenient wide-angle refractor - ordinary 1.25 "eyepieces are sufficient to obtain wide images, for example a Plossl eyepiece with a focal length of 32 mm will give a field of view of 6,6 degrees
Telescope properties • Perfect correction of chromatic aberration thanks to the 2-element lens made of ED FPL-53 glass • 1.25 "helical lift with eyepiece mount and T-2 thread • Standard 20mm backfocus, after removing the backfocus back extension up to 60mm, sufficient for use with SLRs • Fastening to the finder foot with 6 positioning screws included • At 800 g, this telescope is slightly heavier than a standard finder and does not significantly change the center of gravity • 1.25 "paraphocal ring allows you to set a comparable focus point for the eyepiece and autoguider, it helps to find and set the right star for guiding 60 months
