Conventional nominal 12V power supplies are made for use in your "living room". When used outside in the cold, their voltage will drop with temperature. At -10°C (18F), the voltage output may have gone down to only 10.5 V, and the motors of many telescope mounts will behave erratically at such a low voltage. The motor driver electronics will try to compensate for the low voltage by drawing more current (amps) until both power supply and mount electronics will fail to work properly or suffer damage. Many users blame the mount and its internal electronics when an inadequate power supply may be the culprit. The Baader Planetarium 60W Outdoor Power Supply is designed for outdoor use, just like the proven, smaller, Baader Planetarium 19W Outdoor Power Supply. Both, the elbowed disconnect plug as well as the straight pull linkage perfectly protect the power input and electronic board of the telescope against damage when tripping onto the cable. Also this protects the cable itself from breakage. Altogether the distance between telescope and power socket may reach 4 meters. This is longer than usual and assures that the power supply will not become a tripping hazard or dangle in the air. Even for larger telescopes, the power supply can be placed on the ground or onto the accessory tray of a tripod or pillar. The housing is sealed against moisture, but it is not waterproof. So, of course the plugs must not contact wet ground. The Baader Planetarium 60W Outdoor Power Supply continuously supplies up to 5 Amperes at a minimum of 12 Volts, so it is perfect for modern, powerful mounts like the Celestron Advanced VX, CGEM (DX), CGE Pro and CPC HD Deluxe. Of course, it can be used with any mount having a Celestron-Standard receptor (2.1mm x 5.5mm), requiring up to 5 Ampere.

Baader OTP Outdoor Telescope Power 19WThis 12.8 volt /1.5 Amp switching power supply with protective-disconnect plug serves all Celestron telescopes up to the CGEM-DX series. At little higher price it offers enormous benefits compared to common department store indoor units.Conventional power supplies having a 12V nominal voltage are made for use in your "living room". When used outside in the cold the voltage will reduce with temperature. Already at -10°C the remaining voltage output may have gone down to only 10.5 V. The motors of many telescope mounts will behave erratic at such low voltage. Especially the motor driver electronics then tries to replace the missing voltage by draining ever more Amps until both - power supply and mount electronics - will stall or become damaged. Many users then blame the mount and it´s messy electronics - instead of checking wether an inadaequate power supply may be the culprit.The Baader Outdoor Telescope Power supply offers continuous 1.5 Amp/ < 12 volt DC voltage all accross the AC voltage range from 90 to 260volt. Even at extreme cold the voltage can not go down as far as to damage the electronic components or motors of your telescope mount.19 Watt/ 1.5 Amp permanent power ensure ample reserve for smooth tracking even at full photographic instrument load and high torque variations due to changing telescope balance. In addition to the outdoor voltage of 12.8V also the thermal working temperature has been designed for -25°C to +40°C.The connecting cord measures 2.5m in length. This is longer than usual to ensure that the wall plug portion of the power supply can be safely stored down the tripod legs so that the power cord will not become a trip-wire. The ellbowed plug does protect the power cable from accidental breakage and especially the telescope power input socket from damage when actually someone would trip over the cable. When accidentally the cable gets tightened the connecting ellbowed plug will release the cable straight, without ripping or damaging the power socket affixed in the telescope.

Top Offer! TS Optics 17 mm Plössl Eyepiece with 1.25" barrel sizeA good Plössl eyepiece outperforms a simple Kellner. Through bulk purchase, we can offer this type of eyepiece at a price for which you would get only more simple eyepieces elsewhere. Nevertheless, the features are quite impressive. The 17 mm Plössl is a fine all-round eyepiece, it delivers a good performance on planets, but also when viewing nebulae and galaxies. It is often chosen for binoviewers, too, due to the very good ease of view. Areas of application of Plössl eyepieces:Through the four-element design, the Plössl is a true all-rouder. It does not introduce an additional chromatic aberration to the system, in opposite to more simple eyepieces with fewer elements. As a consequence, these eyepieces can be very well used for observing moon and planets with higher magnifications. At lower magnifications, Plössl eyepieces are well suited for observing nebulae, star clusters and galaxies, they convince with a field of view relatively free of distortion. Astrophotographers can also work well with Plössl eyepieces, as they are well suited for eyepiece projection. The MgF2 coating prevents disturbing reflections and provide good contrast. However, many projection adapters are too narrow for the Plössl eyepieces with 32 or 40 mm focal length.

The Moon has the distinction of being the most often viewed celestial object through backyard telescopes. It is undoubtedly beautiful and mysterious, and is one of those constants in our lives that connects us to every other being on our planet. Regardless of who we are or where we live or travel, we all look at the same moon. It is difficult to look at the Moon through a telescope and see all of the details due to its brightness. Our eyes are not ready for the bright beam of light that emits from the eyepiece, and they “stop down”, just as they would when you step out into the sunlight on a bright summer’s day. When we’re in the sunlight, we often wear sunglasses. They help us relax our eyes, protect us from glare, and help us see things more clearly. When amateur astronomers observe the Moon, we use a moon filter. A Celestron Moon Filter provides similar benefits to those of sunglasses...our eye relaxes and opens up to let us see more detail. This is especially important when observing the Moon when it is near full. The Celestron Moon Filter simply screws onto the insert barrel of most 1.25” eyepieces. It only takes a second or two to transform your regular eyepiece into one suited for lunar observations. A Moon Filter is also helpful when observing Venus or bright terrestrial scenes. This filter is not suitable for viewing the Sun.

Our Moon is the most popular object to observe with a telescope. It’s an obvious target that’s easy to locate and full of exciting geographical features to explore. Moon filters enhance lunar viewing by cutting down on the Moon’s bright glare, improving contrast and making faint details easier to observe. Amateur astronomers refer to Moon filters as “sunglasses for the Moon” because they provide a more comfortable view and reduce eye fatigue. This Moon Filter Set contains all the filters you will ever need to observe the Moon during its various phases. The set allows you to choose the best filter to use with different eyepiece and telescope combinations. Use the darkest filter with larger aperture telescopes and lower magnification eyepieces. Use the lighter filters with smaller telescopes and higher magnification eyepieces. This kit is essential for those looking to take the next step in exploring their telescope’s full lunar capability, or for seasoned lunar observers who use a variety of telescopes and eyepieces to observe the Moon.   In this kit, you will receive: Three neutral density (ND) filters: ND96-0.9 13% T, ND96-0.6 25% T, and ND96-0.3 50% T —These filters dim the entire visual spectrum from 400-700nm equally. The ND96-0.9 filter transmits 13% of the incoming light, the ND96-0.6 transmits 25% and the ND96-0.3 transmits 50%. They do not impart any color to the Moon, but reduce lunar brightness. With several ND filters to choose from, you can find just the right level of light transmission for the Moon depending on its phase, the aperture of your telescope, and the magnification of your eyepiece. ND filters can also be used reduce the glare from Venus to better see its crescent phases, and to help dim bright daytime views when using a telescope terrestrially. A Moon & Sky Glow filter — This filter selectively reduces light transmission at different wavelengths and greatly improves contrast for observing subtle lunar features. This filter imparts a very light purple color to the Moon. For those in light-polluted skies, the Moon & Sky Glow filter provides some contrast enhancement when viewing deep sky objects due to the filter blocking some wavelengths associated with common forms of light pollution, e.g. low-pressure sodium (LPS) street lights.  A durable plastic carrying case — The Moon Filter Set comes with a foam-lined plastic case to store all four filters when they are not in use and protect them during transit. Moon map and legend — Familiarize yourself with the Moon, our neighboring world with the help of our handheld Moon map. The Moon map comes complete with a legend highlighting 17 key features to explore including Sea of Tranquility, Tycho, Plato, Copernicus and many more.  Housing Each filter is housed in an aluminum cell, providing a rigid, durable frame for the filter glass. The filters thread onto Celestron 1.25” eyepieces and most other 1.25” eyepieces with a standard filter thread. The filters have threads on the top and bottom to stack with other filters for even more light filtration options.

A good Plössl eyepiece outperforms a simple Kellner. Through bulk purchase, we can offer this type of eyepiece at a price for which you would get only more simple eyepieces elsewhere. Nevertheless, the features are quite impressive.The 40 mm Plössl offers maximum field of view with 1.25" and is a fine overview eyepiece. With its long focal length of 40 mm, it is especially suited for slow telescopes like Cassegrains or refractors not faster than f/8. The image stays still bright, making the eyepiece well siuted for observing nebulae, open star clusters and galaxies, but also for centering of objects. Areas of application of Plössl eyepieces: Through the four-element design, the Plössl is a true all-rouder. It does not introduce an additional chromatic aberration to the system, in opposite to more simple eyepieces with fewer elements.

Omegon T-2 ring for Minolta AF - basic adapter for bayonet to T2 thread This Omegon T-ring lets you adapt the bayonet of your SLR camera to the T-2 thread used as a standard fitting in amateur astronomy. There are a large range of adapters that use it.   What do I need to connect my camera to the telescope? First, remove the lens from your camera. Then attach this T-2 ring onto the bayonet fitting. You will then see a T-2 female thread, to which you can connect virtually any astronomical adapter.   You can connect, for example, a T-2 camera adapter (item 1250) or a focal reducer. These adapters have a T-2 male thread and fit directly onto your T-ring. This combination fits directly onto the focuser of your telescope - firmly attaching your camera to the telescope.   The advantages in a nutshell: T-2 ring from the camera bayonet to T-2 base ring for connecting an SLR camera to a telescope connect any T-2 adapter to this ring

The internal diameter of the eyepiece clamping sleeve is 30.1mm. For optimum positioning, the eyepiece can rotate 360º around its axis in click-stops. The eyepiece can be switched between 1x and 2x magnifications. For viewing comfort, the eyepiece is fitted with a soft fold-down rubber eyecup. An adjustment of +/-4 dioptres is provided to adjust to your eyesight. Suitable for fitting to the polar scopes of Sky-Watcher EQ3, EQ5, AZ-EQ5, HEQ5, EQ6, EQ6-R, AZ-EQ6, SAM & STAR ADVENTURER mounts as well as many mounts of other brands.   

APM Barlow 2" This is the 2" counterpart of our famed 1.25", 2x/1.5x Barlow lens. It is well made both in design and craftmanship. Both lenses are fully multicoated for best-possible contrast and transmission. The lenses have a diameter of 37mm, thus you can even use 2" wide angle eyepieces without vignetting.   Further uses: With a 2" extension tube - 50mm - you will attain a magnification of 2.7x compared to an eyepiece without the Barlow lens. That way you turn a 30mm wide angle eyepiece into an 11mm wide angle eyepiece with comfortable eye relief.   Remove the black anodized lens cell from the Barlow lens and screw it directly into your eyepiece to attain a magnification of 1.5x.  

With the usage of barlow lenses, you can extend the focal distance of telescopes and hence the magnification of your observated deep sky objects.

Omegon LE Planetary eyepieces – powerful eyepieces for star-studded excursions through the night skyThese eyepieces offer an extraordinary combination of elegance and top optical performance to enhance your observations.The LE Planetary eyepieces from Omegon have been engineered for extremely high sharpness and contrast at levels not found in this class.The Omegon LE Planetary eyepieces have an outstanding optical design that caters precisely to the needs of stargazers.Even with Newton telescopes with a fast lens, the LE Planetary eyepieces offer absolute distortion-free images up to the extremes of the field of view.These 1.25” eyepieces are available in focal lengths of 3mm, 5mm, 6mm, 9mm, 12.5mm, 14.5mm and 18mm.Their interior design is comprised of seven lens elements in four groups (18 mm model: five elements in three groups). All lens edges are blackened and glass/air surfaces coated with a multi-layer, high-impact anti-reflex coating.One major difference from traditional eyepieces is the long, 20mm interocular distance, which provides a very pleasant viewing experience. Even spectacle wearers can observe the entire field of view. The apparent field of view is 55°.Compared with similar eyepieces, tests produced greater transparency and more brilliant images with a dark sky background and no interfering stray light.The interior aperture system makes a decisive contribution to reducing stray light. All focal lengths have eyepieces 21 mm across. Omegon LE Planetary eyepieces don’t just artificially enlarge the field of view on its edges, but display a real field without much distortion to the edge area.Using the LE Planetary eyepieces, the exact optical axis does not need to be maintained during observation. The observation is not impaired through vibrations when you look into the device, since there is no vignetting – also known as the kidney bean effect.

Omegon UWA eyepieces - A wide field of view at a competitive price Omegon Ultra Wide Angle eyepieces provide impressive optics with an enormously wide 66° field of view. Just how can wide-angle eyepieces be offered at such a low price? This is very unusual and these eyepieces are well-known among amateur astronomers, and are affectionately known as the ’gold-line’ eyepieces.   For clearly observing planets and deep sky objects Omegon UWA eyepieces are characterized by highly effective coatings and high light transmission, which allows you to enjoy good contrast. These eyepieces are a real asset in the lower price segment.   The advantages in a nutshell: one of the most inexpensive wide-angle eyepieces on the market large field of view of 66° comfortable viewing thanks to the large eye lens filter thread for 1.25” filters fold-down rubber eyecup
