Designed for both astronomical and terrestrial use, Pentax 's 12x50 S-Series SP Binocular features large oversized fully multicoated 50mm objectives to reduce reflection and maximize light transmission through the entire optical path. Utilizing the traditional porro prism configuration gives scenes a rich depth of view for an immersive observation experience and provides a comfortable feel in the hand with a lot of surface area to maintain a sure grip. The large objectives and coatings maximize the amount of light getting to the user's eyes for exceptional low-light capabilities, and its high 12x magnification provides an immersive observation experience whether users are bird watching or comet hunting.

The binocular sports a generous 11mm eye relief and the fold-down eyecups seal against the ocular cavity to block stray peripheral light which can dim images. Its over-sized objectives add weight and bias the center of gravity forward making user fatigue a concern and hand-shake a possibility, so to aid long observation sessions the binocular can be mounted on a tripod using an optional adapter.

A much more affordable option for Subaru owners
Size: 5 Quart, Style: 1 Pack
When you're paying between $16 & $18+ per quart of Subaru brand CVTF 2 fluid this is a much more affordable option. If you look on the back of a Subaru branded CVTF 2 quart bottle you'll see the Idemitsu logo. Doing this job myself saved me over $1000 on what the dealership quoted me to change the valve body and drain and fill my CVT without skimping on anything.

Same fluid as the Subaru brand
Size: 5 Quart, Style: 1 Pack
This is the manufacturer that makes the Subaru cvt fluid. I used this for the drain and fill on a 2019 Subaru Forester. No problem using a hand pump to fill the transmission. Excellent product will use again to service a 2018 Subaru Crosstrek.
