The optical design is the same as any Newtonian, but what makes a Dobsonian a … WitrynaThe short focal length ones (f4 = 600mm focal length to f5 750mm focal length) are especially good for 'deep sky' (Galaxies, Nebulae, Star Clusters). Focal ratios of f6 to f8 are good for planetary views too! Newtonians over f8 (1200mm/150mm) are very cumbersome and should be avoided, principally because they will be spherically …

Turned down edge, which means that the mirror edges are scattering light randomly in the tube instead of focusing it where it belongs. Particularly of interest because due to pi-r-squared the problem any edge problem takes up a large % of the … WitrynaEstudiant els fluids no newtonians. 5è de primària va realitzar una pràctica de laboratori molt interessant. Van estudiar els fluids no newtonians, que són aquells que no segueixen la llei de viscositat newtoniana. Als fluids no newtonians, la viscositat pot variar segons la força aplicada. Això vol dir que poden comportar-se com un ...

However, they do suffer from coma, an off-axis aberration that causes stars at the edge of the field to appear elongated. The faster the focal ratio, the worse this effect becomes.
