Sky-Watcher BK804AZ3 Achromatic Refractor Telescope

Sky-Watcher BK804AZ3 Achromatic Refractor Telescope is a specialist in planet viewing and it delivers best results for the activities like astronomy, nature studies and even sports that are been observed from a distance. Telescopes are the available optical device to support such activities and they are capable of bringing the images closer. The following is the review of this model.

Type: The refractor technology has an edge over the other designs as they are enclosed closely keeping away the dust and moisture to enter the optical tube. The optics are fixed and do not have a central obstruction. This makes the device offer a high-contrast and better resolution output. They are best for planetary observation.

Sky-Watcher BK804AZ3 Telescope Picture

The lens: Having been fully multi-coated with the objective lens diameter of 80mm is sure to offer a clear rich view of the stars, clusters, nebulae, galaxies, planets and the lunar. It does not stop there with the few additional accessories like the correct filtering or by the required projection; the user can view the Sun and even the far off terrestrial views. Without the compromise on the quality the vision of the observed objects make it appear clear crisp and with little chromatic aberration.

The Built: The physical appearance is portable and it has a solid built with the robust structure. The weight of this BK804AZ3 telescope is just 1.5kg that can be easily carried along in all endeavours. Be it in the carry on bag or the backpack, it sits perfectly making it suitable for the travelers. This device suits for the beginners and the hobby astronomers. While the installation is simple in few steps, the few alignments of the finder scope and the mount I what has to be done.

Technical details: The focal length of 400 mm with the focal ratio of F/5 makes Sky-Watcher BK804AZ3 Astronomy Telescope perfect for the general celestial observation. It gives a highest practical power of magnification of 160x while the resolving power is 1.45.

Focus: This Telescope can be focused with the finder scope of 6×30. This is a low power attachment to the telescope that helps to locate the objects easily. The optical tube assemblies are been held firmly and the tube mounting rings helps to rotate and balance the device. The available mount is been made of aluminium and is alt-azimuth mount. This allows to be adjusted to locate and follow the viewing object. Also made to stand on the photographic tripod that is quick and simple to operate. It is been supplied with the multi functional mount plate.

Added features: This BK804AZ3 Sky Watcher Telescope comes with the slow motion control that performs both vertically and horizontally. The lens can be used for the astro-photography that takes interesting pictures of the celestial observation. The terrestrial photography can also be taken with this model.

Verdict: Sky-Watcher BK804AZ3 Celestial and Terrestrial Telescope is a real handy and can be used for the travel purpose. However, the features like the motor drive and the counter weights and Go-to function are absent. The accessory tray is been featured large wall to wall that is stands to be an advantage.

Under this series are available three types of telescope with different technical of which 76EQ Reflector is the one that is been reviewed.

At the outset this series models are been specialised in its design so compact and portable. The materials used are high graded that ensures stability and durability.  For those who desire to view both terrestrial and astronomical observation with the capability of giving correct view of both the land and the sky. It can give a lifetime excitement of viewing the bright images of the Lunar and the Planets. May be the deep sky objects like the galaxies and the nebular does not transform with as bright as the planets like the higher models, yet it can give an overview of the same.

Celestron AstroMaster 76EQ Telescope

Right out of the box:

The excitement begins when the package is been opened to find the telescope and the accessories that are been required to be assembled with the help of the systematic manual provided. It does not require any special degree to do this setting up, as it is user friendly. The tripod can be unfolded instantly and the equatorial mount is been set up with the screws provided. This is been followed by the counterweight bar and the counterweights. It goes on and in few minutes you can enjoy the wholesome benefit of observing far off objects.

Type:

The telescope that is been defined with the reflector type of optical design. This is a Newtonian design that replaces heavy lenses with the mirrors that collect and focus the light. They are popular for its easy maintenance, light in weight, portable and economical. It can take you to the depth of night sky with its enhanced light gathering capability.

Anesthetics:

Celestron 31035 AstroMaster 76EQ Reflector Telescope is quite portable, where the optical tube length measures 914.4mm and it weighs just 8.16 kg. It can be easily accommodated in the back seat of the car and can travel along to bring more pleasure to the trip. The optical coating is made of aluminium and is been fully coated; it consists of a mount of type CG-2 Equatorial. The tripod that is been provided is a 1.25″ Steel Tube Legs. In the case of the equatorial mount the axis of rotation of the telescope is been aliened to the axis of rotation of the Earth which is known as the polar alignment. The mount also plays a vital role in adjusting to the polar axis that is been done by tightening or loosening the rear latitude adjustment screw followed by the front screw. This latitude adjustment ranges approximately from 20 – 60 degrees.

Technical details:

With the aperture which is the diameter of the objective lens measures 76mm, this performs to gather the light from the atmosphere and the higher is the aperture the brighter will be the viewing images. The focal length and the focal ratio are 700 mm and 9.21 respectively. The eyepiece provided are 20mm, which enhances the magnification by 35x and the 10mm eyepiece with the magnification of 70x. The field of view at the distance of 1000 yards is 75 feet or 22.86 metres.

Finderscope performance:

Celestron AstroMaster 76EQ Equatorial Mount Telescope embedded with the finderscope of type Built-on StarPointer, this is the quickest and the most convenient way to make the telescope point to the desired object. It has a laser pointer that directly shines on to the sky. This is just a pointing tool and does not perform any magnification ability. In case of the daytime observation the alignment of the pointer should be done at the nighttime, as the LED dot will not be visible in the day light.

Verdict:

Observing lunar at the low power is easy and by changing the eyepiece is required if you are curious to go deeper in observation. It goes fascinating to view the planets, the Jupiter, the Saturn with its rings and when the contrast is increased, it brings out better details of the object. So is the observation of the deep sky objects that are outside the boundary of the solar system, the use of light filters helps in viewing them better.
