Not only the optics, but also the mechanics of the tracking mount must be top quality and therefore a larger investment is necessary to reach quality imaging. For astrophotographers, instead, the tools requirements have been always much different and far more expensive: in astrophotography no margin of error is allowed, everything must be perfect. The low cost of the wood mount is traded off with a large aperture mirror, beneficial to collect as many photons possible. In fact, a simple telescope version, widely know as Dobsonian, a reflector supported by a wooden altazimutal mount, is sufficient to allow nice visions of planets and deep sky objects. Clearly, the main advantage of the visual observation is the simplicity and lower cost of the required equipment. ![]() Looking into the eyepiece live it has been for visual observers much more exciting than watching the photographic images taken even by professional astronomers. In the first case, the telescopic observation by the simple means of the eye is today still largely practiced, as the simpler way to look to the sky objects. The latest CMOS sensor and digital processing technology allow the astronomy amateur to reach excellent planetary as well fine deeps sky imaging even with “visual “ telescopes, by just adding a minor set of accessories and modifications.Īstronomy amateurs can be divided in two main categories: Visualists and Astrophotographers.
