Newtonian vs sct
WitrynaTable: A rough guide to the differences seen between a tiny 76mm f9 Newtonian and a parabolic 130mm f5 Newtonian: By no means exhaustive, but I think there are several things there that show the essential differences between the different sizes. ... Because Maksutov and SCT telescopes have a closed optical system, this makes them better ... Witryna4 mar 2024 · Moderate costs per inch of aperture compared to other optical designs; Usually a smaller secondary obstruction compared to Newtonians and SCT-variants, meaning higher-contrast views than those designs; The larger, heavier Maksutov corrector lens takes much longer to cool down and adjust to ambient air temperature

Witryna4 maj 2024 · However, the Newtonian, likely f/4 or f/6, will have a wider true field of view, showing more of the sky surrounding an object than the SCT will. The lowest possible … WitrynaA "Newtonian" reflector has a main mirror which is curved and focuses the light back up the tube. It then has a secondary flat mirror at an angle which reflects the image sideways. A Newtonian reflector will have an eyepiece at the top, near the opening, and at 90 degrees to the tube. Newtonian reflectors are one of the simplest designs of ...
WitrynaDifference between Maksutov-Cassegrains and Schmidt-Cassegrain. Their main difference is the corrector lens at the front of the telescope. Both of them use spherical mirrors that induce spherical aberrations. … WitrynaFor starters, Dobsonian telescopes usually have a shorter focal length than Schmidt-Cassegrain telescopes. This means that Dobsonian telescopes have a wider field of view than Schmidt-Cassegrains, but as a result, their magnification isn’t as strong. Dobsonians, despite being physically larger, are both lighter and less expensive than …
WitrynaYes , the more spherical surfaces the better for a smoother wavefront, which gives the DK an edge over RC's on-axis. The Dall Kirkham is similar to a Newt in having one aspheric and one spherical surface involved. Coma on an an F12 is the same as an F6 Newtonian ( which is minimal ) .
