2 inch Banisch S-PP 41 Sun Penta Prism (Made in Germany)

Best devices for solar observing in white light !!!

Suitable for primary focal lengths up to 2500 mm
With ceramic light trap,
The prism has 41mm edge length of the entrance and exit windows.

Needed back focus is 105 mm (same as the Baader 2 inch Herschel prism).

By herschel wedges, the needed back focus is a product mainly of the device body, whereas by pentaprisms is a product of the light path crossing the prisma, yielding a better image quality (the princip is the same because prism diagonals produce better planetary images than mirror diagonals in most of the refractors), so that pentaprism are "the best diagonals" for solar observing in white light.
Eyepiece side: It is provided with a "Teleskop Service" T2 to 2” adapter (with brass compression ring) and a Blue Fireball 2" to 1.25" Twist Lock Self Centering Eyepiece Adapter.
Better than Herschel wedge Prisms (Herschel wedge Prisms are cheaper to manufacture).
Three Baader 2” ND filters are included (0.9, 1.8 and 3.0).

439 USD shipped to CONUS and no PayPal fee. For other destinations a small shipping inrement could apply.
