The precise helical focuser and the possibility of connection via 1.25 inch \/ 31.7 mm connector, as well as the T2 camera connection thread (M42x0.75 mm), allow for the necessary \"autoguiding\" for long exposure, in order to obtain a pinpoint star image. It can also be used as a mini travel telescope. \u003cbr\u003e\n\u003c\/div\u003e\u003cdiv\u003e\u003cb\u003e\u003cbr\u003e\u003c\/b\u003e\u003c\/div\u003e\u003cdiv\u003e\n\u003cb\u003eHigh-quality 8x50 finderscope with adjustable reticle illumination\u003c\/b\u003e\u003cbr\u003e\n\u003c\/div\u003e\u003cdiv\u003eThe image sharpness and viewing characteristics clearly put this finderscope above the level of conventional 8x50 finderscopes. The generated field of view is clear and extremely sharp. In addition, this finderscope has a very large field of view (FOV) of 6.96 degrees. This greatly facilitates the search and adjustment of objects. The scale marks (division = 1 degree) of the reticle are a good reference for estimating distances, and the open center mark also facilitates precise centering of objects. All lens surfaces are weather-protected by multi-coating, and ensure a clear finderscope image thanks to the high light transmission values. The adjustable red LED illumination is powered by two LR41 button cells. The main objective and the reticle can be focused independently, so you can set the perfect focus for your eyes.\u003cbr\u003e\n\u003c\/div\u003e\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\u003cdiv\u003e\u003cb\u003eCompact tracking unit for \"autoguiding\"\u003c\/b\u003e\u003c\/div\u003e\u003cdiv\u003eOne of the main applications of this telescope is \"autoguiding\". With this function, the usually larger photography optics are actively corrected by a smaller guide scope with a second tracking camera. This means that mechanical oscillations that occur in all astronomical telescope mounts in tracking accuracy are measured by the tracking camera and adequately compensated. This is necessary to obtain a pinpoint star image in long exposures in astrophotography, and to avoid star trails. For this purpose, the guide scope is installed in the finderscope shoe of the photography optics and oriented in parallel. If the existing finderscope shoe is not compatible, a suitable finderscope shoe, which is included, can be used. Then, a tracking camera can be mounted with the 1.25 inch \/ 31.7 mm connection located at the rear end or via the T2 thread connection (M42x0.75 mm). This is securely held by a brass locking ring and three clamping screws. Please note the necessary \"back focus\" for your tracking camera. The focal plane (back focus) is approx. 22 mm behind the T2 thread. Precise focusing on the guide star is done by a large knurled wheel of the helical focuser made with precision mechanics. To facilitate the reproduction of the focus point, it has a white millimetre scale from 0 to 28 mm laser engraved. Once the tracking camera has been connected directly or via computer to the telescope mount and the necessary basic settings have been made, the first long-exposure astronomical photos can be taken.\u003c\/div\u003e\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\u003cdiv\u003e\u003cb\u003eUse as a mini travel telescope\u003c\/b\u003e\u003c\/div\u003e\u003cdiv\u003eThis guide scope and finderscope can also be very easily used as a mini travel telescope. By means of optional eyepieces, magnifications from 8x to 40x can be achieved. Almost all eyepieces with a focal length of 5 to 26 mm and a 1.25 inch \/ 31.7 mm connection are suitable. EXPLORE SCIENTIFIC eyepieces of the LER series 52 degrees (art. 02195xx) and 62 degrees (02196xx) are especially recommended.

The finderscope bracket is suitable for many common telescope types such as EXPLORE SCIENTIFIC, BRESSER MESSIER, etc. If the existing finderscope shoe is not compatible, a suitable finderscope shoe, which is included, can be used. It can be attached to the telescope tube using four M5 screws. The distances between the holes of the finderscope shoe are 31.7 mm in the longitudinal and transverse axes. With the six large adjustment screws with gripping knurling, the finderscope can be aligned effortlessly, even with numb fingers. All adjustment and clamping screws have plastic tips to effectively prevent scratching the housing and the finderscope bracket. \u003cbr\u003e\n\u003c\/div\u003e\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\u003cdiv\u003e\u003cb\u003eFEATURES\u003c\/b\u003e\u003c\/div\u003e\u003cul\u003e\n\u003cli\u003eExcellent 8x50 guide scope and finderscope\u003c\/li\u003e\n\u003cli\u003eCan also be used as a mini travel telescope\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003ePerfect image sharpness and good viewing characteristics\u003c\/li\u003e\n\u003cli\u003eLens surface with FMC multi-coating\u003c\/li\u003e\n\u003cli\u003eObjective focal length: 220 mm\u003c\/li\u003e\n\u003cli\u003eMax. permissible camera weight: 550 g\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eRemovable eyepiece\/reticle unit\u003c\/li\u003e\n\u003cli\u003eCamera connection via 1.25 inch \/ 31.7 mm connector or T2 thread\u003c\/li\u003e\n\u003cli\u003eT2 thread: M42 x 0.75 mm\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003ePrecise helical focuser for focusing the field of view\u003c\/li\u003e\n\u003cli\u003eHelical focuser adjustment range: 28 mm \u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eMinimum focusing distance: 3 m \u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eLaser engraved millimetre scale from 0 to 28 mm on the focusing mechanism\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eThe focal plane (back focus) is approx. 22 mm behind the T2 thread\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eSeparate reticle focusing on the eyepiece\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eVery large FOV of 6.96 degrees\u003c\/li\u003e\n\u003cli\u003eWith adjustable red reticle illumination \u003c\/li\u003e\n\u003cli\u003eReticle scale marks with 1.0 degree division\u003c\/li\u003e\n\u003cli\u003ePower supply: two LR41 button cells\u003c\/li\u003e\n\u003cli\u003eBrass locking ring and three clamping screws on the 1.25 inch connection\u003c\/li\u003e\n\u003cli\u003eWith optional eyepieces, magnifications from 8x to 40x can be achieved\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eAlmost all eyepieces with a 1.25 inch \/ 31.7 mm connection are suitable\u003c\/li\u003e\n\u003cli\u003eThe finderscope bracket is made entirely of aluminium\u003c\/li\u003e\n\u003cli\u003eFinderscope bracket with six large adjustment screws with gripping knurling\u003c\/li\u003e\n\u003cli\u003eFinderscope shoe suitable for EXPLORE SCIENTIFIC, BRESSER MESSIER, etc.\u003c\/li\u003e\n\u003cli\u003eAn additional suitable finderscope shoe is included\u003c\/li\u003e\n\u003cli\u003eThe distances between the holes of the finderscope shoe are 31.7 mm in the longitudinal and transverse axes\u003c\/li\u003e\n\u003cli\u003eThe adjustment and clamping screws have plastic tips\u003c\/li\u003e\n\u003c\/ul\u003e\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\u003cdiv\u003e\u003cb\u003eINCLUDES\u003c\/b\u003e\u003c\/div\u003e\u003cul\u003e\n\u003cli\u003e8x50 finderscope\/guide scope\u003c\/li\u003e\n\u003cli\u003eEyepiece unit with reticle\u003c\/li\u003e\n\u003cli\u003eReticle illumination incl. batteries\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eFinderscope bracket with finderscope shoe\u003c\/li\u003e\n\u003cli\u003eInstruction manual\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Explore Scientific","offers":[{"title":"Default Title","offer_id":52791590846807,"sku":"620170","price":173.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0552\/6198\/6860\/files\/0620170_M_1.jpg?v=1770989642","url":"https:\/\/astrotelescopios.com\/en-uk\/products\/buscador-y-guia-explore-scientific-8x50-con-enfoque-helicoidal-y-conexion-de-1-25-pulgadas-y-t2","provider":"Astro Telescopios","version":"1.0","type":"link"}
