A big mirror on a box that costs almost nothing · review
A 76/350 tabletop Dobsonian sold pre-assembled, with two eyepieces, a Barlow and a Moon filter.
The bottom line The smallest complete instrument here — quick to start, easy to store, and asking a little more of its eyepieces than its price suggests.
Seventy-six millimetres of aperture and three hundred and fifty of focal length: f/4.6. Short tubes of this kind frame wide and store easily, and they also ask more of both eyepieces and collimation than a slow instrument does. At this aperture the practical ceiling is modest anyway.
The maker states that the azimuth base comes pre-assembled. For a first telescope that is worth more than another accessory: the gap between opening a box and looking at the Moon is the gap where enthusiasm is lost.
Two eyepieces, a Barlow and a Moon filter. Together the maker quotes 18x to 117x, which is four combinations of the supplied glass. The Moon filter has no transmission figure attached, which is the norm on this shelf and worth noticing all the same.
The title carries National Geographic branding; the marketplace brand field reads Bresser. Both refer to the same product, and this page uses the name printed on the telescope.
