Small focal length vs large focal length

Webb14 jan. 2024 · Plössls have a wide field of view (around 52°), so they can be used successfully for planetary as well as deep-sky viewing.

'Eye relief' refers to how far your eye must be from the eyepiece in order for you to see the entire field of view. Webb26 juni 2024 · The formulae is. (Pixel Size (μm) of camera / Focal length of telescope) * 206.3 = angular resolution (arcseconds/pixel) The longer the focal length of the telescope the smaller the arc seconds per pixel. Conversely the shorter the focal length the larger the number of arc seconds covering each pixel. The pixel size also plays a role.
