The Celestron Star Pointer finderscope is a 1x power (no magnification), or unit power entry level, finderscope designed so you can point the telescope while scanning the sky with both eyes. A mirror lens projects the image of a LED illuminated pinpoint into the line of sight, providing you with a red dot of light to center on the object you want to view.
It’s like having a laser pointer that reaches into the sky, but it’s a siting dot that doesn’t emit a beam beyond the finderscope, which could cause problems when you’re doing astrophotography. The brightness level is adjustable, and the Star Pointer can be used during daytime observing as well. It easily attaches to any Celestron telescope.
