Telescope Guide Scope 50/183mm, 60/230mm Guidescope with Double Helical Focuser
Feature:
20mm Back Focuser
The focuser helps you quickly lock the stars you want to see. The focuser simply moves the attached device inwards or outwards while maintaining its orientation, which means your field of potential guide stars will not rotate as focus is adjusted, further increasing ease of use.
10mm Helical Focuser
After focusing, you can see details of the image clearer and brighter. The focusing accuracy is up to 0.1 mm. The 10 mm focusing stroke will meet your needs for viewing guides.
M42*0.75 & 1.25inches
The Multi-Use Guide Scope features male T-threads on the focuser collar for secure threaded attachment of guide cameras equipped with female T-threads.
And the versatile Guide Scope can double as a straight-through finder scope with an optional 1.25" eyepiece installed. For example, insert a 20 mm eyepiece to create a 9.5x50 finder scope, or insert one Illuminated Centering Eyepieces for use as a finder with illuminated crosshairs for easy aiming. (Eyepieces sold separately).
Double-sided FMC
Fully Multi-coated Glass means multiple coatings on all lens surfaces and all air-to-glass surfaces are anti-reflective multi-layer coated. And FMC lens has greater advantages in increasing the light transmission, delivering bright, clears and crisps images even in low-light conditions.
Stray Lights Elimination
The elimination design improves the observation efficiency since less light is lost due to reflection and improves the contrast of the image by elimination of stray light.
Metal Hoop with Dovetail
The Multi-Use Guide Scope features a machined, knurled metal hoop to make fine focus adjustments nice and easy, while a thumbscrew lets you lock-down the focuser in-place once to complete adjustments. And the plastic on the endpoint keeps the scope itself free of pesky scratches.
Package includes:
1* 50mm/60mm Primary Mirror
1* Guiding Bracket with Dovetail Plate
1*1.25 inch Helical Focuser
6* Metal Thumbscrew
