The\u003cbr\u003eDi features a luxurious eyepiece consisting of five lenses in four groups,\u003cbr\u003eproviding a clear peripheral field of view and the central resolution you expect\u003cbr\u003efrom Hinode. The body is made of magnesium, the focus knob is made of\u003cbr\u003ealuminum, and many other metal parts are used, making it extremely durable.\u003cbr\u003eThese binoculars are nitrogen-filled and completely waterproof.\u003c\/p\u003e\n\u003cp\u003eWe at Hinode spent over six months conducting extensive visual tests before\u003cbr\u003ethe product was released, and we felt a strong response to the D1. At this\u003cbr\u003epoint, when compared to models in the same price range with similar\u003cbr\u003especifications, we can confidently recommend it.\u003c\/p\u003e\n\u003cp\u003eWhen planning the Hinode 8x42-D1 as an 8x binocular for stargazing, we kept\u003cbr\u003ethe following three points in mind.\u003cbr\u003e + Low color shift\u003cbr\u003e- Wide field of view, yet still sharp at the periphery\u003cbr\u003e* Not too heavy\u003c\/p\u003e\n\u003cp\u003eChromatic aberration (color shift) becomes noticeable when the magnification\u003cbr\u003eis increased to 8x or higher. It is not uncommon for the star image to be color\u003cbr\u003eshifted when looking at a particularly bright star through binoculars, but if the\u003cbr\u003edegree of this shift is severe it can be annoying. The D1 uses ED lenses, which\u003cbr\u003ekeep chromatic aberration to an acceptable level.\u003c\/p\u003e\n\u003cp\u003eYou won't notice much chromatic aberration when looking at Venus or Sirius.\u003cbr\u003eYou will notice some chromatic aberration in the peripheral areas of the Moon,\u003cbr\u003ebut it's practically unnoticeable for faint stars.\u003c\/p\u003e\n\u003cp\u003eWhen gazing at the stars, a narrow field of view can make the image less\u003cbr\u003eimpactful, but forcing a wider field of view can worsen the peripheral image\u003cbr\u003eand result in a blurred overall image. The D1 provides a fairly wide field of view\u003cbr\u003e(7.5 degrees) while still maintaining a certain degree of peripheral sharpness,\u003cbr\u003eproviding an excellent balance for stargazing.\u003c\/p\u003e\n\u003cp\u003eThe Hinode 8x42-D1 weighs 688g, which may seem a little heavy for some\u003cbr\u003ewomen. Compared to the lightweight 6x30-B2, it feels heavier. However, the\u003cbr\u003ebody itself is not particularly large, measuring just 123mm high and 127mm\u003cbr\u003ewide.\u003c\/p\u003e\n\u003cp\u003eAlthough it is not as convenient as 20mm or 30mm binoculars, it is not\u003cbr\u003eunmanageable. In order to make it as light as possible, lightweight magnesium\u003cbr\u003eis used for the body, making it lightweight for a 42mm binocular.\u003c\/p\u003e\n\u003cp\u003eMany of the Hinode staff members were originally involved in astronomy-\u003cbr\u003erelated work, and so when it came to creating 8x42 binoculars specifically for\u003cbr\u003eastronomical observation, they had many concerns from the user's perspective.\u003cbr\u003ePlease see the development story at the bottom of this page for more details.\u003c\/p\u003e\n\u003cp\u003eCan it be used for anything other than\u003c\/p\u003e\n\u003cp\u003estargazing?\u003cbr\u003e The advantage of the D1 is that it has an 8x magnification while still\u003cbr\u003emaintaining a 5mm exit pupil diameter.\u003c\/p\u003e\n\u003cp\u003eI don't think this is a big advantage if you're looking to observe birds, animals,\u003cbr\u003eor plants. I generally use the all-purpose 6x30 or the compact 7x20, and if you\u003cbr\u003efeel the magnification isn't enough, I'll use the 8x30 instead of the 8x40.\u003c\/p\u003e\n\u003cp\u003eAs I mentioned above, thanks to the great advances in coatings over the past\u003cbr\u003e30 years, the field of view is now bright enough. When observing birds,\u003cbr\u003eanimals, and plants, I don't think a 5mm exit pupil is necessary unless the\u003cbr\u003esituation is extremely dim.\u003c\/p\u003e\n\u003cp\u003eIn that case, the 8x30 would be about 200g lighter and more compact, and\u003cbr\u003ewould be easier to use. Of course, this doesn't mean that the 8x42-D1 can't be\u003cbr\u003eused for anything other than stargazing, but 700g is a bit heavy for carrying\u003cbr\u003earound.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eDetails\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003eHinode 8x42-D1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMagnification\u003c\/td\u003e\n\u003ctd\u003e8×\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eObjective Lens Diameter\u003c\/td\u003e\n\u003ctd\u003e42 mm (ED lens)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eExit Pupil\u003c\/td\u003e\n\u003ctd\u003e5 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eActual Field of View\u003c\/td\u003e\n\u003ctd\u003e7.5°\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEye Relief\u003c\/td\u003e\n\u003ctd\u003e18 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrightness\u003c\/td\u003e\n\u003ctd\u003e28\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMinimum Focusing Distance\u003c\/td\u003e\n\u003ctd\u003e2.0 m\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePrism Type\u003c\/td\u003e\n\u003ctd\u003eRoof prism (BaK4)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePrism Coating\u003c\/td\u003e\n\u003ctd\u003eFlat prism with dielectric multilayer coating, Schmidt prism with phase coating\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLens Coating\u003c\/td\u003e\n\u003ctd\u003eFully multi-coated (7 layers), water-repellent and hard-coated\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBody Material\u003c\/td\u003e\n\u003ctd\u003eMagnesium body with aluminum focus knob\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e688 g\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e127 mm (W) × 132 mm (H) × 50 mm (D)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInterpupillary Distance\u003c\/td\u003e\n\u003ctd\u003e57 – 75 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWaterproof Rating\u003c\/td\u003e\n\u003ctd\u003eWaterproof, nitrogen-filled; submersible to 3 m for 3 minutes\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCountry of Manufacture\u003c\/td\u003e\n\u003ctd\u003eJapan\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eColor Options\u003c\/td\u003e\n\u003ctd\u003eBlack, Navy Blue\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAccessories Included\u003c\/td\u003e\n\u003ctd\u003eSoft case, objective lens cap, eyepiece cap, strap\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eIn the Box\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eHinode Binoculars 8x42-D1\u003c\/li\u003e\n\u003cli\u003eSoft case\u003c\/li\u003e\n\u003cli\u003eObjective lens cap\u003c\/li\u003e\n\u003cli\u003eeyepiece cap\u003c\/li\u003e\n\u003cli\u003estrap\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWarranty\u003c\/h3\u003e\n\u003cp\u003eHinode Warranty\u003c\/p\u003e","brand":"Hinode","offers":[{"title":"Default Title","offer_id":48526369194213,"sku":"HIN-8x42-D1","price":1200.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0652\/6245\/2965\/files\/hinode1.webp?v=1772908035","url":"https:\/\/astronomyplus.com\/products\/hinode-binoculars-8x42-d1","provider":"Astronomy Plus – Telescopes \u0026 Astrophotography Canada","version":"1.0","type":"link"}
