Premium astronomical eyepiece from Baader Planetarium with 4.5mm focal length and 76-degree apparent field of view provides a wide, immersive 'spacewalk' experience when viewing stars, galaxies, nebulae, and star clusters. Also gives excellent views of the Moon, planets, and other solar system objects. (See 'Important Note' in the Product Description below to make sure this eyepiece is a good choice for your telescope).
Long eye 17.5mm relief for a comfortable viewing experience, even when wearing eyeglasses. Fits 1.25" and 2" telescope focusers without the need for separate adapters (does not fit telescopes
with 0.965" focusers). Excellent build quality and sealed watertight housing ensures years of trouble-free field use with your telescope.
Multi-coated lenses and internal baffling ensure minimal light scatter and high image contrast. Minimal aberrations and distortion for excellent views of stars and extended deep-sky objects over the full field of view.
Size and weight are optimized for use with astronomy binoviewers to allow observing with both eyes (optional binoviewers, sold separately, require two eyepieces of the same type and focal length). Eyepiece weight is 13oz (370g).
Includes removable eye guards to keep stray light out of your eyes while observing. Rubber grip for easy and secure handling, even while wearing gloves. Threaded for standard astronomy filters (not included). Also features M43 photo-video adapter thread for imaging applications (requires Baader M43-T2 adapter or Baader Hyperion Digital T-rings, both sold separately).
