Stellarvue 13 X 80 mm Straight Through Finderscope - Matte Black
If you want to reach deep the Stellarvue 13 X 80 mm Finder scope is the way to go. Gathering 130 times the amount of light you naked eye does, you will have no problem seeing those dimmer star clusters and nebulae. Weighing only 2.2 pounds, this finderscope is much lighter than other competitive 80 mm finderscopes. All optics within this system are fully multicoated enhancing light transmission and contrast.
This Stellarvue 13 X 80 mm Straight Through Finderscope works with all Stellarvue standard 80 mm finderscope ring systems. The 80 mm finder-scope comes in a neutral matte black finish that goes well with any telescope regardless of color.
This finder provides a straight through, inverted image only. It will not work with a diagonal. The 2" helical focuser has a 1.25" adapter and the E3023R crosshair eyepiece that works with optional illuminators. For a true porthole view of the sky, use Stellarvue's 2" 26 mm 68° crosshair reticle eyepiece. The 80 mm finderscope has a tube diameter of 85 mm. NOTE: You will need to purchase a Stellarvue Ring set to hold this finder scope unless you already have one which has the correct dimensions to accept this finderscope tube.
