DESCRIPTION

The EQ8-Rh provides the next generation of Sky-Watcher’s popular high capacity mount, the EQ8.

The R models offer a refined design to allow for better balance and more modern features to cater to today’s high end imagers.

Built-in cable management

• • • USB 3.0 USB hub (4 ports)
    • 2.1mm Power port (3 ports)
    • 3 serial ports on the back of the saddle
    • The EQ8-Rh features built-in cable management. This removes cable drag from hanging cables and reduces the risk of cables getting caught during imaging session. This capability also improves the mounts capabilities for remote use.

The built-in USB 3.0 hub allows you to simply plug in your camera, guider, filter wheel and other USB accessories into the hub below the saddle plate and connect them using a single USB cable plugged into the rear of the mount. No more tangled mess of cabled hanging or need for multiple cables running around the mount.

Another addition to the cable management system is the three built-in 2.1mm ports situated next to the USB hub. This allows your accessories to also be powered through the mount. This reduces the need for multiple power adapters and other accessories. The ports can be run off of a single power source providing a cleaner set up and less cables.

On the gear of the saddle are three serial ports for various accessories such as ST4 guide cables and other serial based accessories. Like the rest of the cable management this reduces the hanging cables and provide a neat connection to the mount.

Motor Positioning

EQ8-RH feature improved balance from their predecessor with redeposited motor housings. This improve the mount’s balance over all.

Belt Drive

Both mounts feature belt drive on both the RA and Dec axis. This allows for smoother guiding and reduced backlash.

Auto-Home

EQ8-RH feature built-in homing sensors. This allows the mount to know its positioning more accurately from its start positioning.

Improved Clutches

The EQ8-RH models feature improved clutches allowing for sturdier lock under heavy loads. Simply use the large levers to engage or disengage the axis of choice. The clutch lever are larger than the original EQ8 making it easier to adjust with gloves.

PC Direct Connect

EQ8-RH also feature the new PC direct connect feature. Now you can easily connect your mount to your computer without the need of a hand controller. When paired with the SynScan Pro app. for Windows the mount can be aligned and controlled direct from a PC. This makes imaging refined and easier, especially for those with permanent set ups.

EQ8-Rh On-Axis Encoder

The EQ8-RH takes a step further with all the listed features above but adds a higher level of precision. The Rh (h for High Res.) features an on-Axis Renishaw TONic incremental, 11.8 million tick, encoder on the RA axis. This allows the mount to have extremely precise tracking and guiding for long exposure imaging. With the encoder built onto the RA axis this removes periodic error to nearly zero in RA with an accuracy of 0.11 arc-seconds! The EQ8-Rh offers a pro level mount for the series astro imager.

EQ8-RH Mount Specifications

The essentials:

• Impressive impressions at all distances
• Excellent close focusing distance below 1.90 m
• Ideal contrasts and transmittance for the best visual perception of color nuances and the smallest details

The ULTRAVID 8X20 are brighter, sharper, more compact, more functional and robust than previous binoculars of this lens size.

There is no question that these compacts are true Ultravid-class. Almost all the Ultravid-elements that the developers could miniaturize found there way into these "mini-binoculars" which fit comfortably into almost any pocket.

The use of aspherical lenses offers the observer a sharp image right to the edge without color fringing and because of the short close-up distance these little Ultravids bring close up things even closer.

The 25mm and 20mm BR binoculars live up to the name "Ultravid" in the case robustness too: because a new developed vulcanization method ensures that the rubber armoring is inseparable from the metal housing even in the harshest conditions. Their robustness is further evidenced by being guaranteed watertight up to 5 m (16.5ft)and nitrogen filled to prevent fogging. They also come with high quality accessories.

The ULTRAVID 8X20 BR series come in shock-absorbing black rubber coating but also available is the Ultravid BL series in a noble black leather. This leather design gives the binoculars a classic elegance and guarantees a long life.

Includes a woven carrying strap, eyepiece cover, Cordura case with belt loop.

The essentials:

• Unsurpassed compact
• Versatile in its application possibilities: 8x magnification for the best detailed recognition on the shortest distances (1.8 m close range) and excellent overview in the distance
• Size: 111 x 93 x 39 mm
• Rubber-armored BR variant

Produce a larger area of illumination for your 9.25”, 11” or 14” Schmidt-Cassegrain or EdgeHD telescope by using the this adapter. When this adapter is paired with our Off-Axis Guider, these two imaging accessories allow you to use the full image circle in our larger scopes. This configuration is especially helpful to owners of larger format cameras, such as the Canon 5D or 6D, since their full frame can take advantage of the more substantial area of illumination produced by larger optical tubes.

What’s New!

The Large SCT & EdgeHD Adapter V2 for Off-Axis Guider has a longer optical length—38mm. The adapter’s longer length provides DSLR cameras back-focus spacing for Schmidt-Cassegrain and EdgeHD optical tubes in conjunction with the Off-Axis Guider without the need for extra adapters or spacers.

Body

The Large SCT & EdgeHD Adapter V2 for Off-Axis Guider is machined aluminum black anodized. The internal surfaces are sandblasted to help prevent glare and provide the highest contrast. The adapter has a knurled surface providing a great gripping surface for threading and unthreading.

The Star Adventurer weight is an indispensable accessory for increasing the payload of the mount. The counterweight bar can be connected to the adjustable dovetail bar for balancing a telescope or a camera with a telephoto lens. The weight is approximately 1kg.

This dovetail bar kit allows you to replace the wider CGE dovetail bar found on most Celestron 8” Schmidt-Cassegrain and 8” EdgeHD optical tubes with a narrow dovetail, allowing them to be used on mounts that require the narrower CG-5 dovetail bars.

The transmission properties of the L-RGB Filterset 1.25in Type 2c filters are optimized for CCD astrophotography. The set allows taking images in correct colours for all types of objects. Where other brands make strange compromises, we do the best colour reproduction possible. Both stars as well as objects that emit only in spectral lines, are reproduced in their true colors. You get CCD images with perfect colours, as if the objects where bright enough to be seen with photopic vision. This feature is the main difference between Astronomik filters an those of other manufacturers.

The following aspects have been most important for the design of our filters:

- simple image processing for the user

- highest transmission (nearly 100%) for short exposure times

- adjusted transmissions of the individual filters for optimal colour reproduction

- the use of industry standards

Astronomik doesn't stop thinking at the step of taking the picture. More important a tool should be given to the astrophotographers that offers a simple and elegant editing process. To maintain the colour, we calculated our filterset for the sRGB color space, that is used as an industry standard from most manufacturers of monitors, printers and imaging software. As a user, you do not need to spend time learning about colourimetry and colour spaces. We have solved the special problems of astrophotography for you.

Due to the high-precision machining of the carrier substrate, our filters are parfocal with wedge errors below all usual margins. In order not to be the bottleneck in a high-quality optical system Astronomik filters are of course diffraction limited. Issues concerning focal distances as well as the exact location of the images of each colour image are not a problem at all!

Main use

The L-RGB filter set divides the spectrum into its components red, green, blue and luminance. Thus colour separation can be achieved with pure b/w CCD sensors. The separation corresponds to the colour sensitivity of the human eye according to DIN 5032. By using the sRGB color space it is possible to maintain the color of the image throughout the entire image processing and output. With an Astronomik L-RGB filter set and your camera you create ideal raw material for image processing in the sRGB color space.

Swarovski ATX 30-70×115 Technical Data

Swarovski ATX 115 at a glance

There’s never been anything like it: a spotting scope with such outstanding detail resolution and up to 70x magnification. This even pushes optical tests to their limits. Despite the 115-mm objective lens, this is a slim spotting scope weighing in at just 2 kilograms.

In a nutshell, it ticks all the boxes for any birder wanting to discover an albatross gliding past an oceanic headland.

Clarity right up to the edge – SWAROVISION Field Flattener

This type of image definition has never been achieved before in any other spotting scope, thanks to the field flattener lenses creating a virtually flat image. Even the finest structures are reproduced with razor-sharp clarity right up to the edge with no need for constant refocusing.

The result: every detail is instantly captured, producing a perfect image without any distortions.

Maximum contrast – Including HD optics

A highly innovative optics design combined with fluoride- containing HD lenses minimise interfering colour fringing. This enables maximum
colour fidelity and leads to a significant improvement in resolution and contrast.

The result: an even more lifelike, contrast-rich image.

A complete view – Large field of view and high zoom range

Nothing escapes you. Thanks to their wide field of view, the ATX/STX spotting scopes provide you with a broader, more exciting platform for your viewing experience.

In spite of their high zoom range, the new generation of spotting scopes offers a large field of view. This allows you to achieve optimum magnification and detail recognition and also makes it extremely easy for you to search for and find objects, especially if they are in motion.

Eye relief plus – Large field of view even for spectacle wearers

SWAROVISION features a long eye relief and the removable twist-in eyecup is individually adjustable.

The result: even spectacle wearers can enjoy a large field of view, not to mention the inimitable edge sharpness. An additional eyecup has been specially developed for spectacle wearers to further increase viewing comfort.

Maximum colour fidelity – Optimised coatings

The enhanced lens and prism coatings (SWARODUR & SWAROTOP) give noticeably better colour reproduction combined with even greater transmission. SWAROCLEAN coatings on the outer lens surfaces create a non-stick effect, making it easier to clean.

The result: even more impressive observing experiences, even in low light.

Ingenious System

The new modular design offers previously unimagined flexibility and you are free to choose the perfect solution as the situation dictates. In collaboration with experts we have developed digiscoping adapters that open up a new realm of ways in which to observe and share the most beautiful moments.

Perfectly designed down to the smallest detail, you will be equipped for any situation.

Just one hand

When every second counts. Imagine a plover flitting over the shore one minute and taking off into the sky the next. The ATX/STX spotting scopes ensure that you are prepared for moments like this. This is because the new position of the zoom ring, which is now directly behind the focusing ring, makes it easier to handle. It means that you can zoom and focus with one hand, while steering the spotting scopes direction with the other.

This completely new ergonomic design offers a crucial benefit for digiscopers in particular. They can now use the camera quickly, easily and accurately with one hand, while the other concentrates on zoom and focus.

Easy to transport

Not a gram too heavy for top optical performance. Size and weight is the name of the game for all those who like to travel or spend long days in the field. The ATX/STX series means that bulky spotting scopes that are difficult to pack and heavy to carry are a thing of the past.

The modular design enables you to store the objective and eyepiece modules separately and the smaller dimensions also mean that you can easily and safely store individual modules in your luggage.
