EXPLORE SCIENTIFIC 8x50 90°PolarFinder+Amici-Prism (Refurbished)

Explore Scientific 8x50 illuminated finder scopes (available in straight-thru and right angle versions) produce images that are right-side-up and left-to-right corrected views, which makes it easier to find objects in the sky. The Explore 8 X 50 Straight-Thru Erect Image Illuminated Finder Scope, with its scale markings and open Center, not only helps you center objects precisely, but gives a reference of the exact field of view in Degrees. The deep red Illumination can be adjusted to just the right brightness. The eyepiece has comfortable eye relief and produces a 6,97 degrees field of view. Both the eyepiece and the main objective can be focused independently so that you can obtain perfect focus for your eyes. The straight-thru finderscope weights just under a pound (450gr), and measures 216mm" x 63mm" x 58mm".

Simply set up and explore the Moon, Venus and co. straight away: With the BRESSER Stellar 60/800 AZ lens telescope, getting started in sky observation is quick and easy. The complete set already contains the necessary equipment for your new hobby: the astronomical lens telescope with 60 mm aperture and 800 mm focal length, the azimuthal mount, the tripod and extensive accessories for your voyage of discovery through the solar system. The beginner's telescope is very easy to use and therefore ideal for getting children excited about astronomy. Well-tried classic for completely new impressions - the telescope Especially for beginners and children, this classic lens telescope - also known as an achromatic refractor of the Fraunhofer type - makes it easy to enjoy astronomical sights. The modern, precisely coated optics ensure good imaging properties. Another strength of the optics: the 60 mm aperture and the 800 mm focal length result in a very large focal ratio (ratio of the aperture to the focal length) of about 1 to 13.3 (F/13.3). The result: a very sharp image with good contrast. The long focal length also makes the telescope a specialist for lunar, solar and planetary observation. However, open star clusters and globular clusters are also guaranteed to amaze you when you look through the telescope. And how big do the celestial objects appear? With the aperture size, the starter telescope achieves a resolving power which lets you enjoy really sharp images at up to 120x magnification. Technically, this entry-level telescope is capable of more - theoretically up to 600x with the included accessories. But: with increasing magnification, the image sharpness can slowly decrease. Of course, not only the telescope plays a role when it comes to magnification. The air turbulence in the atmosphere (seeing conditions) also affects your view of the night sky. The foundation for your view into space - mount and tripod The telescope tube is held securely on the height-adjustable aluminium tripod with azimuthal mount. And this azimuthal mount has a great advantage: it is very easy to operate. Just like a common photo tripod, you simply swing the telescope manually to the left and right, up and down. Perfect for beginners in astronomy and children. But where to put the accessories? To keep them within easy reach, just place eyepieces, solar filter etc. on the storage plate between the tripod legs. All you need for a quick start in astronomy - the accessories For your fascinating view of the night sky, the telescope for beginners comes with lots of accessories. Among them you will find a LED-viewfinder, with which you can easily keep track of the sky. It is mounted parallel to the actual telescope and projects a red dot onto a small screen. When you look through the viewfinder, the red dot appears to float in front of the sky - right where your starter telescope aperture is pointing. This way, the finder helps you to align your optics precisely and locate celestial objects - before you then take a closer look through the magnification of the telescope. You determine how much magnification you get by choosing the eyepiece. You will see: The two eyepieces (4 mm, 20 mm) included in the set alone offer quite different perspectives on the beauties of our cosmos. For the most versatile views possible, the socket diameter of 1.25 inch (31.7 mm) also complies with an international, manufacturer-independent standard. So if you want to expand your astronomy set later, you will have a wide choice of models. You have found an astronomical highlight and want to see even more details? Then place the 3x Barlow-lens between the telescope and the eyepiece. It will triple the magnification. Meanwhile the included 90-degree star diagonal mirror lets you comfortably admire the night sky. Even though your entry-level telescope is pointed upwards, you don't have to lie down underneath to enjoy the view. Instead, you look in comfortably from the side. But it is not only at night that we can observe the beauty of outer space. During the day, our own Sun is the undisputed star in the sky. So attach the solar filter to the aperture of your beginner’s telescope and safely observe sunspots and granulation. CAUTION: Never point the telescope at the Sun without the solar filter! To capture and share your unforgettable moments in astronomy, take your very own snapshots with the smartphone adapter. Thus the very first step towards astrophotography is easily taken! Look forward to your complete astronomical starter package and a whole new view of the Sun, Moon and planets - with the BRESSER Stellar 60/800 AZ lens telescope.

The optics of the VMC260L are significantly better than the traditional Schmidt-Cassegrain telescope. Despite its high 3000 mm focal length, it is just 650 mm long. Featuring a large 260 mm aperture, the telescope collects large amounts of light for serious professional observations and photography of the planets and countless deep-sky objects. Thanks to the dielectric mirrors, the VMV260L guarantees razor-sharp images and maximum brightness. The open lens barrels cool the telescope quicker than conventional closed Cassegrain systems. The telescope can be used with an optional 0.62x focal reducer to reduce the aperture ratio to 1:7.1. This shortens the exposure times and allows you to photograph large objects. The telescope comes with a standard dovetail bar and a carry handle that doubles up as a camera holder for night sky photography. The Finder Scope and the Vixen Flip Mirror is not included in this version ! FEATURES Very short cool-down time thanks to open lens barrel Optimised system for photography Very transportable – only 650 mm long Lightweight design – only 12.1 kg Large 260 mm aperture Built-in correction lens in front of the secondary mirror Backfocus without Reducer: 149,4 mmBackfocus with Reducer: 63,5 mmTotal weight: 12.1 kg WHAT’S INCLUDED VMC 260 telescope/lens barrel Carry handle VIXEN standard dovetail barFinder Bracket ShoeEA60 mm to 50.8 mm SX

Top viewfinder telescope with upright field, illumination, 90° view and pole viewfinder engraving - image sharpness and viewing behavior raise this viewfinder significantly above the level of the usual 8x50 viewfinder telescopes. The upright image field facilitates orientation. Multi-Coating on all surfaces. This polar finder is mainly intended for the observer with a transportable telescope. The 90° view facilitates operation, and with the help of the pole scale and the lighting, a telescope can be quickly and safely aligned to the celestial pole. The upright field of view makes the handling together with the high image sharpness a pleasant experience. The lighting is powered by two LR41 button cells.
