QHY5III678c is a new planetary and guiding camera of the 2nd generation of QHY5III series, the upgraded version of QHY5III178M/C, with excellent near-infrared high sensitivity.

USB-c connectivity

The new QHY5III678c series cameras all use the USB3.2 Gen1 Type-C interface. Compared to the USB3.0 Type-B interface used in the previous generation, the Type-C interface has a longer life and is more flexible.

Tips: It is recommended to use the official standard Type-C data cable of QHYCCD. As the market is flooded with a large number of poor-quality Type-C cables, casual use may lead to the camera malfunctioning. If you use your own spare cable, please make sure it is a high-quality cable.

Universal Guiding Interface

The custom interfaces of the previous generation of planetary cameras and guiders has been replaced in the QHY5III (Ver.2) cameras with a more universal ST-4 compatible guiding interface. Now, even if the guiding cable is lost or damaged, you will be able to easily get a replacement on the market at a low cost.

Indicator LED

The new QHY5III (Ver.2) series of cameras is equipped with a status indicator at the back of the camera. If the camera experiences an abnormal status, the multi-colored indicator light will help to determine the situation with different colors signifying different conditions. During normal operation this indicator light is off, so there is no worry about light contaminating the image.

Swarovski ATX 65 Spotting Scope Technical Data

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.

Sony EXview HAD CCD II ICX825 sensor - Super Sensitive

The fact that you're reading this this shows you've made it past the most common trap in choosing a camera for astroimaging - how many megapixels is it?

There are 2 variables in your camera that are far more important to consider when imaging faint deep sky objects. Sensitivity and noise.

The sensitivity tells us how many precious photons will be converted to signal...this is were the new Sony ICX825 shines! But how much more sensitive is it? Compared with Atik's previous 314L+ at 650nm, the 414EX is 60% more sensitive. In fact, the 414EX is even more sensitive than the already spectacular 460EX, making it the perfect camera for the enthusiast with a limited budget. The graph below shows the striking difference between the ICX285 and ICX825:

Low noise and effective cooling

Atik's 414EX has more than just great sensitivity.

Another feature of the 414EXmaking it a winner for astrophotography is it's exceptionally low noise. When capturing a stunning portrait of your favourite deep sky target you will understand how delicately faint it is. This means the data you wish to capture is sparse.

If the electronics of the camera add noise (unwanted signal) to your image the end result will be lacking in detail and contrast. To ensure the contribution from noise is minimised Atik's 414EX has thermoelectric cooling that can easily lower the CCD chip to 30ºC below ambient, and is regulated, so that your image calibration is consistent. This results in a noise level so low that for most applications dark frames are an option rather than a requirement. The upshot is that you can spend more time imaging!

FocusLynx Control Hub Quick Start Guide

This 2" to 1¼" adapter allows more in-travel for 1¼" eyepieces than our "flat-top" or "high-hat" adapters. This adapter is designed to attach to the 1¼" eyepiece barrel and convert the eyepiece for use with a 2" focuser or diagonal. The main application is for 1¼" eyepieces that may need more in-travel due to limited focuser range of your telescope.

The "In-Travel" model achieves the following amount of in-travel benefit compared to our conventional 2" to 1¼" adapters.

Tele Vue's Delos 3.5mm is a short focal length eyepiece that will deliver high power magnification. Importantly though it still achieves a generous 20mm eye-relief and wide 72° apparent field of view. Amazing in well corrected refractors with short to medium focal lengths. High powered views without the need for a Barlows or Powermate!

There is a good chance the TeleVue Delos will be seen as the ultimate combination of performance, viewing comfort and price. If you've been keeping a spot in your case for an affordable, premium eyepiece, you should consider a Delos - you won't be disappointed! Lessons learned from the tremendously successful Ethos series were applied to develop this long eye-relief, 72° apparent field of view eyepiece line.

All focal lengths feature 1.25" barrels making them suitable for almost any telescope or even bino-viewers!

Tele Vue Delos 3.5mm - Specifications

• Model # EDL-03.5
• Focal Length 3.5mm
• Barrel Size 1.25"
• Apparent Field of View 72°
• Eye Relief 20mm
• Weight 499g
• Field Stop 4.4mm

Background:

In 2011 Tele Vue introduced the Delos, mid-to-short focal length line of 20mm eye-relief, 72° apparent field of view eyepieces. Every optical, mechanical, and ergonomic aspect was rethought to achieve reference-standard performance for any visual application.

The Delos was conceived as a narrower field Ethos. Reducing the field to 72° allowed freedom to increase eye-relief, while controlling pupil aberrations, all without making the eyepiece too large. With Ethos performance standards as benchmarks, the Delos design achieves full field sharpness, virtually perfect f θ (theta) distortion mapping, and color neutrality. Image fidelity is maximized utilizing glass matched multicoatings and anti-reflection surfaces throughout the eyepiece.

Contrast is further enhanced with a new, continuously adjustable height eyeguard system that can be locked in any position. Since the Delos eye-lens measures a quite large 35mm in diameter, preventing stray light from reflecting off the first surface and extraneous light from entering your eye pays off in a nice increase in perceived contrast. The eyeguard's sliding action allows for positioning the soft rubber eyeguard at the ideal height to suit the observer's preference. Indicator marks on the eyepiece body are handy reference guides for setting your perfect position. The eye-guard can also rotate for Dioptrx users.

Sky & Telescope Hot New Product for 2012 Award

Review of the 6mm & 10mm Delos from Astronomy Magazine, December 2011

Excerpts from Sky & Telescope, June 2011, review of Delos eyepieces:

WHAT WE LIKE:

Essentially perfect optics
"Immersive" observation experience

WHAT WE DON'T LIKE:

I spent several nights viewing the Moon, Saturn, stars and nebulae with a variety of telescopes … .

The Delos eyepieces are "easy to look through … . They have flat fields, delivering absolute pinpoint stars from edge to edge with no hint of color aberration. The view, especially during the daytime, is very pure with no noticeable color tint. And there wasn't a hint of ghosts or reflections, even with the brightest stars".

"What caught me a bit off guard, however, was something that's best described as the observing experience. It was distinctly pleasurable."

"I have the sensation of looking out of a circular window rather than into an eyepiece."

Like our traditional Dobsonians, the new Collapsible Dobsonians feature Skywatcher’s patented tension adjustment control on the altitude bearings. This eliminates the need and added cost of clumsy counterweight systems to balance the telescope.

To top it off, all of the new Collapsible Dobsonians are shipping with ultra smooth Crayford focusers.

A Dream Come True

Today digital imagers require mounts with tracking accuracy up to 60 times better than that needed for visual observing. Erratic errors introduced by badly manufactured or poorly assembled components within the mount are often encountered in cheap mass produced mounts. Losmandy's use of the highest quality materials and their attention to detail provides the level of accuracy and precision needed in demanding applications.

New GEMINI 2 SERVO SYSTEM

Precision made in the U.S.A by Hollywood General Machining with software developed in Germany, the Gemini servo based, GOTO system delivers a high torque servo based computerized drive system never before seen in high quality amateur telescope mountings.

Gemini allows both stand alone and PC based control of Losmandy's G8, G-11 and Titan series mounts. The GOTO control electronics have typical Losmandy hallmarks of being fully machined, anodized and brushed, with beautifully radiused edges that look like part of a Losmandy system, rather than a third party bolt on. The new electronics control system case has been designed to fit on the existing control case mounting tabs on all Losmandy G-8, G-11 and HGM200 tripods.
