Available again soon - This high quality Celestron 9 x 50mm straight through finderscope is complete with a quick release mounting bracket and boasts a 5.8 degree field of view for easy object location. It is the same finderscope and bracket used on Celestron CPC series telescopes. The finder’s achromatic doublet lens is fully coated with antireflection materials for high light transmission and high contrast. It focuses by loosening the ring behind the fully coated objective lens cell, screwing the lens cell in or out to focus for your particular eyesight, and tightening the ring to lock at the correct focus.The quick release bracket comes with the hardware that threads into the existing finderscope holes drilled on the rear cell of any 8" to 14" Schmidt-Cassegrain telescope.
The finder can also be used with many reflecting telescopes, but may require some drilling in the optical tube to install it. Two finger tightening thumbscrews lock the finder back into precise collimation after the finder is removed from your scope for transport or storage and then reinstalled. The bracket has an easy spring-loaded X-Y axis adjustment for collimating the finder crosshairs with the center of the main telescopes field of view.
