Astro-Tech 15mm Titan 1.25" 70 degree field super wide angle Eyepiece, ATT15

This Astro-Tech 15mm Titan is a very wide 70 degree field medium power 1.25" eyepiece at a very economical price. It is ideal for lunar observing, resolving globular clusters, picking up detail in emission and reflection nebulas, etc. Its 15mm focal length nicely fills the gap between the 25/26mm eyepiece that typically comes as standard equipment with most telescopes and an 8/10mm high power planetary/binary star splitting eyepiece. With short focal length refractors and fast focal ratio reflectors, it gives an extraordinary "picture window on space" image. A f/4 Meade 8" Schmidt-Newtonian reflector, for example, yields a 3.75mm exit pupil, 54x, and a generous 1.3 degree field of view thatýs good for observing open clusters such as the Pleiades; large nebulas such as the Lagoon, Veil, and Orion; and large globulars such as M-13 and Omega Centauri. All will fit nicely into the field of view, with a framework of black velvet sky around them to set off their subtleties. Globular clusters and nebulas are vivid and nearly three-dimensional.

The 66mm f/6 Astro-Tech AT-66 refractor, on the other hand, has a magnification of 27x with this eyepiece, with a 2.5mm exit pupil and an immense 2.63 degree field (over five times as wide as the full Moon).

Even medium and long focal length telescopes provide impressive views. Use this 15mm Titan on an 8" f/10 catadioptric scope and you still get a 0.52 degree field at 133x, perfect for the Moon and globular clusters like M9, M13, and M22.

The 7mm eye relief is somewhat short for those who must wear eyeglasses while observing due to astigmatism, and will somewhat vignette the field. This is of minor concern, as even those who donýt have to wear glasses while observing will find they have to move their head from side to side while observing to see the entire huge field of view.
