The Sky-Watcher GT Series AZ-EQ5 Go-To Mount combines the advantages of the equatorial mount with the simplicity of the alt-azimuth system. In fact, the AZ-EQ5 is a hybrid mount usable in both these configurations. The equatorial mode is ideal for astrophotography while the alt-azimuth configuration is more practical for observation as polar alignment is not required. Moreover, two telescopes can be simultaneously mounted in alt-azimuth configuration.

The popular SynScan Go-To system allows full control of both R.A. and Dec. axes with 9 slew speeds and 5 arcminute pointing precision, allowing you to quickly and accurately locate objects across the night sky.

The Go-To system can automatically slew the telescope on command toward planets, stars, nebulae, galaxies, clusters and much more. The Sky-Watcher SynScan system has 42,900 memorised celestial objects for an amazing journey in the night sky. The Deep Sky Tour function suggests a list of the most interesting deep sky objects currently visible, so even the novice astronomer can easily observe faint objects at the touch of a button. Once achieving alignment, the patented Freedom Find™ dual encoders will then keep track of your position to within 4.2 arcminutes. The mount will retain alignment even after releasing the clutches and manually pointing the scope to a new part of the sky.

The AZ-EQ5 is equipped with two SNAP ports for dual control of camera shutter release. Working with the SynScan hand control’s “Camera Control” function, a user can take batch exposures in up to 8 groups of “Exposure-time & Frames”. An indexer on the R.A. worm gear keeps track of its current position, so that the Periodic Error inherent to all worm gear driven mounts can be learned and permanently corrected for. These features make the Sky-Watcher AZ-EQ5 a fantastic partner to high focal length telescopes and astrophotographers alike.

Saxon RST Researcher Stereo Microscope Specs

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.

FocusLynx Control Hub Quick Start Guide

OPTEC Lepus .62x Telecompressor is optimized for 100mm of distance between the last lens surface and the image plane. Measured from the telecompressor flange, this distance works out to 105mm. Assuming a native focal ratio of f/10, the Lepus 0.62X will reduce the effective focal ratio to approximately f/6.2. Shifting the image plane outward will provide additional reduction but a loss of star quality at the edge of the images. The optimal distance for most SCT's is 100mm with the exception of the C9.25 EdgeHD SCT.

Standard Edition Lepus 0.62X telecompressor lens designed for use with any telescope having the TCF-S or other 2-inch focuser in place. Works well with Meade ACF f/10 and f/8 coma-free SCT telescopes. The Lepus 0.62X Standard Edition is housed in a 2-inch barrel-like assembly and will fit into any telescope receiver for standard 2-inch eyepieces.

The camera side connection for the Lepus 0.62X telecompressor is a broad dovetail known as the OPTEC-2100. The proper back-focus distance to the camera image plane is maintained with Optec's custom camera-specific Lepus mounts available separately below. The OPTEC-2100 interface also allows easy connection to the Pyxis 2" rotator in place of the standard 2-inch nosepiece. When connected to the camera, Lepus will appear as a long 2-inch nosepiece that fits into any 2-inch focuser or eyepiece receiver.

Special DSLR adapters are available from stock for Canon and Nikon cameras which hold and maintain the 100mm on-axis back-focus distance.

The Lepus can be used with other telescope designs but is not parfocal. Therefore, some re-focusing will be required. Performance is not guaranteed with all telescope optical designs and the Lepus is not recommended for use with Ritchey-Chretien telescopes.

Key Features of the Nikon Monarch HG 8x42

The Nikon Monarch HG 8 x 42 binoculars are the most advanced Monarch binocular ever:
Enjoy sharp and clear views to the periphery, with an outstandingly bright, wide field of view.

Realising a wide field of view, with stunning clarity all the way to the periphery

The wide apparent field of view provides a spectacular viewing experience. While achieving a wide field of view, the Field Flattener Lens System ensures sharpness and clarity all the way to the lens periphery. What's more, the use of extra-low dispersion (ED) glass corrects chromatic aberrations that cause colour fringing, delivering a contrast-rich, high-resolution image.

Achieving a bright view that provides natural colour fidelity

High-quality multilayer coatings are used on all lenses and prisms while dielectric high-reflective multilayer coating is applied to the roof prisms, achieving a bright view of up to 92% or higher light transmittance, and natural colour fidelity. The quality of view is as if seen with the naked eyes. Also, phase-corrected coating is applied to the roof prisms for enhanced resolution and contrast.

Sturdy, lightweight, waterproof body handles tough environments

Employing magnesium alloy ensures a sturdy, lightweight and compact body. The high level of waterproof/fogproof performance with nitrogen-filled body resists water pressure to a depth of 5m and prevents fogging inside the optical system, even in low-pressure environments up to altitudes of 5000m. Scratch-resistant coating is applied on the objective lens and eyepiece surfaces. An assured field of view is provided in harsh environments such as snow-covered mountains, exposed coastlines or under bad weather conditions.
