Product information

The SkyVision Compact Dob range features optics made in France, housed in a finely crafted CNC machined chassis with carbon fibre truss tubes. Collimation is so easy, your barely aware of it. A soft yet rigid CNC cut foam mirror cover protects the optics without any risk of damaging them if dropped. The secondary mirror is extremely rigidly held in stainless steel spider vanes. Optics are fully adjustable and the telescope is light and easily transportable, despited the large apertures.

Talk to us about adding the servo drive system for full GOTO and tracking, even enabling high power planetary imaging.

Not only does the sensible engineering make this telescope a pleasure to use, but optics are also very good with a faultless star test and a quick cool-down time. What's more, the price is very reasonable indeed.

Altair staff comments: "We of course had to order one to try it ourselves. When our first unit arrived, we opened the wooden primary mirror case (which is of course separate for transport) and found a full multi-page optical test report including traditional Focault knife edge tests, as well as high contrast images testifying to the smoothness of the optics. Below that, a pair of white cotton gloves, and below that the mirror itself nestling in it's custom wooden carrying case. To give you some idea of what these optics are capable of, our T300 unit easily displayed Ganymede as a clearly defined disc, with plenty of detail visible on Jupiter's cloud belts, as well as the Great Red Spot (well it was more a washed out pink) easily picked out. Although there wasn't a Jovian moon transit going on at the time, we felt that these optics were so smooth, they would easily pick out a moon against the planet, something often only the preserve of refractors. Deepsky objects were bright, and stars were sharp points at low and high power. When our eyes had become dark-adapted, we kept coming back to the Orion Nebula which showed plenty of detail and took on form and substance with dark lanes visible and the Trapezium cluster at the centre shining brightly. The Pleiades were also amazing, with young, white-hot stars filling the field. After an hour of effortlessly slewing this telescope around the heavens, we felt this was one of the nicest Dobsonians we had ever used."
