Avalon M-Zero with StarGO Bluetooth with TPOD90 [AV-1MZR002-T90]

$4,392.55 CAD ~~$7,320.92 CAD~~

Avalon Instruments: Avalon M-Zero Single Arm Equatorial/Altazimuth four in one Mount, Fast-Reverse technology, including STAR Bluethooth GoTo, Dovetail GP'' clamp, weight 5.5 Kg., carrying bag, Power supply 15V/4 A.

Portable Astronomy

The new M-Zero has been designed to revolutionize the world of portable astronomy. The unique and innovative design, the light weight and the small dimensions, the greater versatility and higher quality make it the perfect tool for the traveling astronomy.

Several mounts in one

The M-zero is more then one mounts: a Standard Equatorial when used with longer optics, a Single Arm with the great benefit of non requiring meridian flip using compact optics, an Alt-azimuthal mount for visual astronomy and, finally, an excellent time-lapse platform for panoramic photography and video shooting.

Double Telescope Setup

Thanks to the new Dual-DEC system, it is possible to install a second telescope in the opposite side of the declination axis. Considering this capability it is possible to use a great range of optics starting from a small (4-5 kg/8.8-11 lb) refractor up to a double setup with a total weight of 12-13 kg/26.4-28.6 lb, obtaining performances so good to get it over the need of a bigger mount.

The StarGO Control System has been designed to be wireless used also by means of a smartphone or a tablet, through the Bluetooth connection. The M-zero can be quickly set in the Alt-azimuthal mode for the visual observation with larger telescopes and binocular or to make panoramic pictures or video sequences with time-lapse features.

Zero Maintenance

The virtually zero maintenance, the long lasting materials used and the possibility to easily update the StarGO firmware and software allow the M-zero to be always ready to use, up to date, competitive and extremely reliable!

Transportability

The M-zero can be balanced, in most cases, with less than 1 kg/2.2 lb counterweight due to the possibility of placing the declination arm in different positions relative to the right ascension arm. The M-zero and the T-pod 90, requiring limited room, may be easily arranged inside a medium size carry on case allowing a convenient setup for air traveling astro-amateurs.

Light and Strong

Made entirely from anodized aluminum, worked using 5 axes CNC machines.

The mount weights only 6 kg/13.2 lb and, combined with the new T-Pod 90 tripod, reaches a total weight of 12 kg/26.4 lb.

Technology and Innovation

The top quality construction level, the innovative Fast-Reverse with zero backlash technology and the new StarGO control system allow the M-zero to get excellent performances in the photographic use, with guided longer time expositions, even using 2 meters focal length telescopes such as 8” SCT and RC.

THE POLAR SCOPE MONT can be performed by using the polar scope mounted on the RA body that can be rotated as shown in the picture aside to the upper position for a comfortable adjustment position.

The standard kit for the polar alignment is provided with the following components:

1. Polarscope

2. support stand provided of scope fixing knobs and dovetail attack with fixing grip knob.

3. Illuminator cap provided of red LED and connection cable to the StarGO.

4. Optional kit with diagonal

The kit can be provided with a Losmandy polar scope

In this case the item 1 shall be of the type suitable to the Losmandy scope in which the graduated scale is not provided. Another option that greatly facilitates the polar alignment operations is the special star diagonal.

This optional component allows to perform the observations through the polar scope in a more confortable position. This option is available for both types of polar scopes.

X-Guider Avalon [AV-9XGD001]

$232.46 CAD ~~$464.91 CAD~~

specialorder On sale

Avalon Instruments: X-Guider Avalon: High Precision micrometric Head (Tangent Mount Assembly) for guide telescope. Off-Axis +/- 5° complete with upper GP clamp.

The X-Guider is a Tangent Mount Assembly of the telescope; is extremely compact and innovative for found the guide star in astrophotography, which comes from a long experience in the field of astronomical photography.
Its main characteristic is that while having a load capacity of more than 6 kg is very light, with a mechanical simple, robust, without slack and above all it has the ability to make adjustments with one hand through two convenient knobs, look much important when one must act in uncomfortable condition.
Once the final position is found possible to lock the elevation through two knobs and since the azimuth is ensured by the pressure of a spring very strong, the system is totally free from play and mechanical deflection, absolutely essential factor in a system of autoguider
Another important aspect is the low profile that allows you to maintain a low center of gravity resulting in less weight to balance.
The system is equipped with a dovetail standard GP for fixing the guide telescope and a second removable flange GP, through which it is possible a fast and efficient mounting in parallel on a standard bar GP is the side that superimposed on the main telescope.
