Telescope Focal Length Reddit. This will give you a wider max potential. For eyepieces, the focal length is inverse. Here is an instructional video featuring. If you plan on favoring deep sky observing, then get a telescope with a shorter focal length / focal ratio. A 6mm would be 200x power and. If this is true, then why do long. Focal length refers to the distance that light travels from the objective lens or primary mirror to the eyepiece. So i've heard that the longer a telescope's tube is, the longer the focal length, thus having a more narrow fov. A 40mm eyepiece would be 30x on an 8 dob (1200mm scope length / 40mm eyepiece). Move the paper until the light dot is in in focus on the paper, then measure the distance to the mirror. When the eyepiece is in focus, its focal length is the distance from the scope’s focal plane to the point inside the eyepiece where the light rays. That is the focal length as well. For dimmer, deep sky objects you should be concerned with the balance of aperture and focal length (with a focus on aperture for. The focal length is essentially the distance (in millimetres) that light travels inside the telescope from its entry point (the aperture) to the exit point (the focuser where. A 20mm would be 60x power.
