Home Telescopes Explore Scientific Telescopes Explore Scientific 165mm f7 Apo Carbon Fibre
This excellent premium telescope is the currently largest representative of a new line of apochromatic refractors by Explore Scientific. The completely newly designed optics use FPL-53 extra low dispersion glass, delivering stunning sharpness and contrast without any trace of colour abberation. For a apochromatic refractor of this size the focal ratio is relatively fast - the f/7 optics is thus also very suitable for astrophotography. For this reason we added one of the worlds top focusers - the high precision and the famed rigidity of the 3" focuser make focusing an easy task - and unwanted movements of the sensor during exposures do not happen. Delivery is normally 2-3 business days with this product.
The result of this combination of outstanding optics, top level mechanics and the relatively low weight is an extremely versatile telescope that will not only give images of the moon and planets that are perfect. It will also exceed the expectations of even the most demanding amateur astronomers in the field of astrophotography.The Explore Scientific ED APO 165mm f/7 Carbon FPL-53 3" Hex Focis the latest development in the line of Explore Scientifics excellent Apochromatic range of refractors. This 5-inch instrument offers superb colour correction and pin-sharp views and images, due to its triplet design lens, which features one FPL-53 ED element, offering excellent spherical aberration control and colour correction with a guaranteed polystrehl value in the high 97%. No one telescope "does it all", but a 6-inch Apo certainly covers most of the bases required of a versatile large observer's telescope. It will show significant improvement over a 5-inch class refractor in terms of light gathering power and resolution, making it a better choice of instrument for visual observation of lunar, planetary and deep sky targets. Not only that, but this telescope is an excellent astrograph, with a medium-length focal ratio, which delivers excellent deep sky images (which can be reduced in field size and equivalent focal length yet further with the use of the Explore Scientific 0.7x Focal Reducer-Corrector) and can also be used to impressive extent for imaging of the planets and the Moon (wed recommend the use of one of the excellent Explore Scientific Focal Extender Barlow for solar system imaging).While not as lightweight as the samller Triplets in the Explore Scientific range, at 12.9kgs weight, the Explore Scientific ED APO 165mm f/7 Carbon FPL-53 3" Hex Foccan be mounted to equatorial mounts in the EQ6 class and upward (though wed recommend the minimum of the Explore Scientific G11 PMC-Eight GOTO Mount or Skywatcher NEQ6/EQ6-R Pro Synscan for imaging purposes). This telescope comes with the excellent Hexafoc focuser system, which comprises of a hexagonal drawtube, which minimises lateral shift which is present in lesser quality systems. The focuser has a 10:1 dual speed focus knob, which allows for fine control of focus, whatever the sky conditions. The 3" drawtube offers an unvignetted aperture, which users of full frame format cameras are sure to appreciate.The Explore Scientific ED APO 165mm f/7 Carbon FPL-53 3" Hex Foc is supplied with heavy duty tube rings and a standard Losmandy-style mounting plate. A handle is also supplied which has a channel running down its centre, in which a bolt can be seated, which allows a piggyback camera to be mounted for widefield astrophotography.Explore Scientifics 2" 99% reflectivity star diagonal, with 2" to 1.25" step down ring is also supplied, alongside 2 screw in extension tubes which will need to be fitted to the Hexafocs drawtube in order to get the telescope to a straight through photographic position.Specifications: Excellent colour correction Retractable dewshield Lightweight carbon fibre constructionWhat's in the box: 165mm tube CF (165/1155mm (6.5" f/7.0) 3.0" HEXAFOC Dual Speed Focuser 2 Diagonal mirror with 99% coating Tube rings with handle 3 Losmandy-type dovetail DeLuxe Flight case with wheels
