An essential tool for manual guiding, the GA-4 adapter projects an illuminated reticule of 6 concentric rings onto any 1.25" eyepiece of your choice. The built in 3X Barlow ensures you can use a lower powered eyepiece that has plenty of eye-relief to keep guiding as comfortable as possible. This adapter also allows you to move the rings without having to move the eyepiece making the centering of a guide-star as easy as possible. Indispensable is the word most frequently used when manual guiding is spoken of.
