Focusers

It takes more than excellent optics for your telescope to truly perform. If you want to capture the intricacies of our Moon’s winding Hadley Rille or the spiraling arms of the Pinwheel Galaxy, you will need to have a superior focuser in your astronomical arsenal. With an Explore Scientific dual-speed focuser, you can smoothly find and hold that perfect crisp image.
