Porroprism

Pentax 10x50 PCF WP II£146.00

With its porroprism design, useful 10x magnification, bright 50mm aperture, fully multi-coated optics and waterproof/fog-proof construction the Pentax 10x50 PCF WP II is the 'classic' choice for astronomy! 

Pentax 12x50 PCF WP II£162.00

This 12x50 binocular offers 20% more magnification than the 10x model with slightly less field-of-view. An excellent choice for astronomy, particularly when mounted on a tripod.

Pentax 20x60 PCF WP II£198.00

If you are fortunate to have a room with a view over fields, the sea or an estuary then the high-magnification Pentax 20x60 mounted on a tripod is perfect!  The field of view is narrow but optical quality is superb, sharp to the very edge!  

Needless to say these would also be an excellent choice for astronomy.

Pentax 8x40 PCF WP II£136.00

High-quality fully multi-coated optics and a comfortable, waterproof, nitrogen-filled body make this 8x40 porroprism binocular ideal for birdwatching and hand-held astronomy.
