It seems that from near London this month Mars with its moons is too low in
a light polluted sky for practical visual observation of those moons with a NexStar 11 SCT. It scarcely seems useful to employ over 200x magnification, though for objects much higher above horizon a higher magnification is sometimes easy. I have however been pleasantly surprised to see Triton at about 12 arc seconds separation from Neptune on one evening recently when my local sky transparency was above average ( though still rather greyish orange colour ). Another point of interest has been observing minor planet 64 (Angelina) magnitude circa 11.6 which is retrograding within a degree of Neptune (decreasing to minima of separation about 9th September and 18th October). Although Phobos and Deimos are obviously far beyond reach, Triton and Angelina are pleasant solar system consolation prizes ! Ant |
