Make your focusing for astrophotography an easy and magic task. About Bahtinov mask The Bahtinov mask is a device used to focus small astronomical telescopes accurately. It was invented by Russian amateur astrophotographer Pavel Bahtinov in 2008. Accurate focusing of telescopes and astrographs is particularly of concern to those involved in astrophotography. The telescope is pointed at a bright star, and a mask is placed in front of the telescope's objective (e.g. primary mirror). How does it work? Set up your telescope and imaging equipment as normal. Then simply locate a bright star (maybe Spica?) with your telescope, attach the Bahtinov mask to your telescope and watch the diffraction spike pattern around the star as you adjust the focus. When the middle diffraction spike is centered in the outer spikes, you're in focus. Very little focusing travel is required to move the inner diffraction spike, which means the focus is extremely accurate. Program type> Suitable for telescopes for Dew Shield or Front Outer Diameter From 75mm -114mm (2.95inch - 4.5nch) - For 80mm, 100mm, 102mm ED Skywatcher and Other Refractors Package Include: Bahtinov Mask 3 X Brass bolt P.S:

When placed over the front of a telescope, handy Orion PinPoint Telescope Focusing Masks make it easy to achieve quick and precise focusing without guesswork. Also known as Bahtinov masks, these focus aids feature a laser-cut slot pattern that produces a distinct, intersecting 3-line pattern once accurate focus is achieved in any type of telescope. Orion PinPoint Focusing Masks will help astrophotographers save time and avoid frustrating, fuzzy results caused by slightly defocused exposures. With a PinPoint Mask installed on an imaging telescope, just focus on any bright star within or near the celestial object you want to photograph and adjust focus until the intersecting 3-line pattern is displayed indicating precise focus has been achieved. Wow, that was fast! Besides astrophotographic applications, PinPoint Focusing Masks are also useful for visual observations when fast, tack-sharp focusing is desired. Three Orion-exclusive adjustable rubber-sleeved pegs equipped with thumbscrews clamp onto the outside of your telescope tube or dew shield to hold the PinPoint Mask firmly in place. Orion PinPoint Focusing Masks are easy to install and remove so you can achieve precise focus and quickly start capturing astrophoto exposures. Each Orion PinPoint Focusing Mask can fit a range of telescope tube diameters. For example, this 228-263mm ID Orion PinPoint Focusing Mask will fit telescope tubes with an outer diameter ranging from 228mm to 263mm (8.97" to 10.35"). Made of laser-cut black plastic. Flat for easy storage and transport.
