| 2.3x40mm erect-image extra-widefield finderscope. The optics of WideBino28
and an LED reflex sight finder are combined to yield red reticles in the
center of 28-degree FOV erecting field. The reticles are 0.5-degree and
2-degree concentric circles. Brightness adjustable with a pulsed or continuous
illumination of the reticles. Collimation function with 3 thumbscrews equipped.
Large dewcap to cover the reflex screen and the objective lens is made
of GFRP (Glass-Fiber Reinforced Plastic), eliminating dew and stray lights
to keep good image contrast. A specially shaped GFRP dustcover is standard.
Easy clip-on / clip-off mounting to baseplate - no screws necessary. Comes
with 2 baseplates letting you use it on two telescopes. The baseplate can
be fixed with double-sided adhesive tape (included) or a screw. WideFinder28
has a lot of advantages such as "4 or 5 times larger field of view
than a normal optical finderscope", "1 or 2 magnitude darker
stars can be detected than a normal reflex sight finder", "right-side-up
erecting image" and "illuminated reticles". Those features
embody an ideal form of a finderscope for astronomical use. Compact and
lightweight to fit various telescopes and binoculars. Especially recommended
to Dobsonian users. |
