Need to restore your optics to their original performance level? The Orion Optics Cleaning Fluid for Coated Lenses safely removes harmful oil and dirt from all coated lenses which increases resolution and light transmission.

The Orion Deluxe 6-Piece Optics Cleaning Kit contains everything you need to care for any optical surface. Includes Ultra Brush Dust Remover, Dust Pro Compressed Air, Cleaning Fluid, 2 Booklets of Premium-Grade Lens Tissue, and Ten Cotton Swabs.

For cleaning the lenses in your telescope or binocular, the Orion Microfiber Optics Cleaning Cloth lifts dirt, fingerprints, water and oil from surface without scratching, streaking or smearing delicate lens surfaces. The cloth is machine washable.

For testing the accuracy of your tracking system, or centering stars for GoTo system alignment, the wide field of the Orion 20mm Illuminated Centering Eyepiece makes it easy. Just use the illuminated crosshair to acquire and center any star.

The Tele Vue Paracorr type 2 coma corrector eliminates or reduces coma in reflector telescopes as fast as f/3. Works visually or photographically, and the top is tunable to optimize the performance with any eyepiece and telescope combination.

With this handy laser collimator, you'll get fast, dead-on alignment (collimation) of your reflector telescope's optics. Our second-gen model ensures seating exactly parallel to the focuser's mechanical axis for consistent and accurate alignment.

The Baader MPCC MkIII virtually eliminates coma in fast Newtonian reflector telescopes. Designed for astrophotography with telescope focal ratios ranging from f/3.5 to f/6, this Coma Corrector delivers tack-sharp stars across a 35mm frame size.

Use this handy adapter to accurately center any 1.25" eyepiece, collimation tool, astrophotography camera, or other 1.25" astronomy accessory in a telescope's 2" focuser tube.

To enjoy the best views from a reflector telescope, the optics need to be in precise alignment (also known as collimation). Using the Orion Telescope Collimating Eyepiece helps ensure perfect Newtonian mirror alignment for great results every time.

Corrects coma and field curvature inherent in fast Newtonians from f/3.5 to f/6, rendering sharp stars across the entire field of view or image frame. Works for visual observing and astrophotography. Fully multi-coated optics with 75mm backfocus.

Keep your reflector telescope's optics precisely aligned for sharpest images with Orion's Quick-Collimation Cap. Easy to use, it fits 1.25" focuser collars or 2" focusers equipped with a 1.25" adapter. Collimation instructions included.

Also known as Bahtinov masks, Orion PinPoint Focusing Masks produce a distinct, intersecting 3-line pattern once accurate focus is achieved in any type of telescope. Three Orion-exclusive adjustable padded pegs provide a secure grip.
