Orion 228 - 263 mm ID PinPoint Telescope Focusing Mask


This handy PinPoint Focusing Mask from Orion is fixed to the front of an optical tube to achieve fast and precise focusing without having to do any guesswork. Also known by the name Bahtinov masks, these Orion PinPoint Focusing Masks have a laser-cut slot pattern that signals accurate focus has been obtained in any type of telescope by displaying an apparent intersecting 3-line pattern.

Installing an Orion PinPoint Focusing Mask on an imaging telescope will help astrophotographers save time by averting those discouraging, fuzzy results produced by slightly out of focus exposures. With this focus aid, users only have to fixate on any bright star within or close to the celestial object you want to image and modify focus until the intersection 3-line pattern signals that this has been achieved. Aside from astrophotography, PinPoint Focus Masks can also be used for visual purposes when prompt, tack-sharp focusing is desired.

Orion PinPoint Focusing Masks firmly attach to the outside of your optical tube or dew shield using three Orion-exclusive adjustable rubber pegs with thumbscrews. Installation and detachment are a cinch, enabling astro-image exposures to be captured quickly once exact focus has been obtained.

Made of laser-cut black plastic with a flat design to enable easy storage and transport, this Orion PinPoint Focusing Mask works with telescopes that have an outside diameter between 228 mm and 263 mm (8.97" to 10.35").
