  1. Monday 11/11/19 Transit Mercury. Come to see a planet passing in front of the Sun! There was no time for something better. My grab and go set up PST 40mm on a new mount! The sun was quiet. Nice granulation and very low activity on the disc line.

    Messier 11, The Wild Duck Cluster (also known as Messier 11, or NGC 6705) is an open clusterin the constellation Scutum. It was discovered by Gottfried Kirch in 1681. Charles Messierincluded it in his catalogue in 1764. Constellation Scutum Right ascension 18h 51.1m Declination −06° 16′ Distance 6,200 ly (1,900 pc) Apparent magnitude (V)6.3 Apparent dimensions (V)14.0′ The Wild Duck Cluster is one of the richest and most compact of the known open clusters, containing about 2900 stars. Its age has been estimated to about 250 million years. Its name derives from the brighter stars forming a triangle which could resemble a flying flock of ducks (or, from other angles, one swimming duck).(Wikipedia) DAY: Sunday DATE: 28/8/16 TIME: 22:00 SCOPE: Dob 10px Sky-Watcher F.L.1200/4.7 EYEPIECES: Excplore Scientific 20mm F.O.V 68° LOCATION: Mammari

    Messier 57 The Ring Nebula (also catalogued as Messier57, M57 or NGC 6720) is a planetary nebula in the northern constellation of Lyra. Such objects are formed when a shell of ionized gas is expelled into the surrounding interstellar medium by a red giant star, which was passing through the last stage in its evolution before becoming a white dwarf.

    Eastern Veil Nebula (NGC 6992/5) Right ascension 20h 45m 38.0s Declination +30° 42′ 30″ Distance 1470 ly Apparent magnitude (V) 7.0 Apparent dimensions (V) 3 degrees (diameter) Constellation Cygnus Physical characteristics Radius 50 ly Designations NGC 6960,6992,6995,6974, and 6979, IC 1340, Cygnus Loop, Cirrus Nebula, Filamentary Nebula, Witch's Broom Nebula (NGC 6960),Caldwell 33/34 The Veil Nebula is a cloud of heated and ionized gas and dust in the constellation Cygnus. It constitutes the visible portions of the Cygnus Loop (radio source W78, or Sharpless 103), a large but relatively faint supernova remnant. The source supernova exploded circa 3,000 BC to 6,000 BC, and the remnants have since expanded to cover an area roughly 3 degrees in diameter (about 6 times the diameter, or 36 times the area, of the full moon). The distance to the nebula is not precisely known, but Far Ultraviolet Spectroscopic Explorer (FUSE) data supports a distance of about 1,470 light-years. The nebula was discovered on 1784 September 5 by William Herschel (Wikipedia).
