Warning notes
- General safety instructions DANGER Risk of suffocation! Improper use of this product can result in suffocation, especially for children. Therefore, carefully observe the following safety instructions. Keep packaging materials (plastic bags, rubber bands, etc.) away from children! There is a risk of suffocation! Keep cords, ribbons, and similar materials away from children! They could accidentally strangle themselves and suffocate! NOTE Risk of material damage! Improper handling can damage the device and/or accessories. Therefore, only use the device according to the following safety instructions. Do not dismantle the device! In the case of a defect, contact your dealer. They will contact the service center and may send the device in for repair.
- Never look at the sun through an eyepiece/telescope without a certified protection filter. A moon filter can never be used for solar observation. The moon filter is only suitable for moon observation. The solar filter must be mounted in front of the telescope opening, not at the eyepiece. Otherwise, the concentrated light beam through the optics will immediately destroy the filter foil, leading to severe eye damage, including permanent blindness.
- Never leave the optics unattended. Children and inexperienced adults could point the telescope at the sun without proper precautions and lose their eyesight.
- Do not expose the device to high temperatures.

Vixen ASG-CB90 Carbon Tripod
£500.00*
Despite being developed for heavy mounts, the Vixen ASG CB90 carbon tripod is one of the lightest tripods on the market.
The ASG CB90 tripod was originally designed for the new AXJ mount. However, it is also ideally suited to the tried-and-tested SX, HF2, AP, GPD2 and GP2 mounts.
The hand nuts can be loosened to extend the tripod by one section.
The legs of the ASG CB90 tripod can be secured by a reliable screw cap and are equipped with a 2.5 cm interval scale marking.
FEATURES
2-section carbon tripodLightweight and portable

Vixen Encoder for AXJ Mount

(44.09% saved)
Make your AXJ mount more comfortable and precise with high precision encoders! The Vixen AXJ encoders allow you to manually move to the celestial objects via the monitor.
Generally, computer-controlled mounts have an automatic "go-to" system where the position of the objects through a 2-star allighnment
must be stored before the observation.
Once you have done this, the mount is able to find the objects automatically.
However, if you loosen the clamping levers on the mount while using the "go-to" system,
the telescope loses information to identify the object positions and the "Go-to" becomes unusable.
For this reason, the telescope could not be moved manually. However, with the AXJ encoder, this is now possible.
You can "go-to" one object and manually adjust the next by releasing the clamp, without losing the positioning information on the next "go-to".
On the high resolution monitor of the STARBOOK TEN control you can now adjust the objects comfortably by hand.
The second big advantage is an enormously high tracking accuracy with a periodic error <0.5 arcseconds which allows long time exposures
of faint celestial objects without an autoguiding system. This is a dream for any serious astrophotographer.
The AXJ encoders are mounted inside the mount, and thus do not affect the dimensions of the AXJ mount.
So there is no need to buy a larger storage case. FEATURESRA Encoder
