It is not only an optical axis calibration eyepiece, but also support functional expansion.\u003cbr\u003e- Easy to solve the problems about the height of the secondary lens, focus mount tilt.\u003cbr\u003e- Not only on-axis optical axis calibration, but also surface optical axis calibration.\u003cbr\u003e- Support no main lens center mark calibration.\u003cbr\u003e- Support telescope assembly accuracy calibration.\u003cbr\u003e- Helping to better understand the optical axis.\u003cbr\u003e\u003cbr\u003e\u003cb\u003ePackage Included:\u003c\/b\u003e\u003cbr\u003e- 1 x Calibration Eyepiece\u003cbr\u003e- 1 x Pack of Secondary Lens Thumb Screws","brand":"TeSeek Official","offers":[{"title":"Default Title","offer_id":48189436166380,"sku":"96002","price":41.36,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0755\/9669\/3740\/files\/1747275317-1.jpg?v=1787043993","url":"https:\/\/teseek.com\/products\/cyck-newtonian-reflective-optical-axis-terminator-calibration-eyepiece-screws-for-skywatcher-2-inch-to-1-25-inch-interface","provider":"TeSeek Official","version":"1.0","type":"link"}
