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 118-153mm ID Orion PinPoint Focusing Mask will fit telescope tubes with an outer diameter ranging from 118mm to 153mm (4.64" to 6.02").

Made of laser-cut black plastic. Flat for easy storage and transport.

Limited Warranty against defects in materials or workmanship for one year from date of purchase. This warranty is for the benefit of the original retail purchaser only.

Annals of the Deep Sky is a comprehensive reference that guides amateur and semipro astronomers into every mind-boggling corner of the observational universe. Each volume presents extensive descriptions of prominent stars and deep-sky objects. No other popular work in astronomy provides the comprehensive historical background and astrophysical appraisals of prominent stars and celestial objects.

In volume 12 of Annals of the Deep Sky, explore the realms of Hydrus, Indus, Lacerta, Leo, Leo Minor, Lepus, Libra, and Lupus. Featured objects in Hydrus include NGC 602, a young version of the Orion Nebula, and NGC 1466, a bright, rich globular cluster. In Indus, the galaxy pair NGC 6935/6937 presents very different spiral-type morphologies. Lacerta harbors BL Lacertae, the prototype of a class of active galactic nuclei.

Leo includes the famous Leo Triplet and the striking pair M95 and M96, and Leo Minor includes the two interacting systems of Arp 107 and NGC 3395/3396. Lepus has R Leporis, the symbiotic star SS Leporis, and an incipient planetary nebula.  Libra includes the Algol-type variable Delta Librae, HD 140283, and NGC 5728, a triple-ringed Seyfert 2 galaxy.

Finally, Lupus hosts the Lupus Clouds, among the nearest low-mass star-forming regions; IC 4406, an edge-on planetary nebula; and NGC 5643, a grand design spiral galaxy with complex inner structure.
