This month I received thirty four observations from five members (one new to deep sky section); three sketches and thirty one images in total. This number would have been much lower had new member Paul Crossland not included images he made earlier in 2016 - generally clear skies were the exception for all parts of the UK in January.
Michael Kinns, observing from Eastry, made sketches of two open clusters, NGC1893 in the constellation of Auriga (below left) and NGC1647 in Taurus; using a 200mm f6 Orion Optics (UK) Newtonian reflector at 100x and 67x. NGC1647 is about 150 million years old, about 1,800 light years from the Earth and can be found near Aldebaran, alpha Tauri, which is much nearer to us at 65 light years.
Paul Crossland, observing from Liverpool, sent in a total of eighteen images. He use a Skywatcher ED80 refractor and Canon 450D DSLR. The first four, below clockwise, are NGC7635, the "bubble" emission nebula in the constellation of Cassiopeia, to the right the same object with a wider field of view, C34 the western part of the "veil" supernova remnant in Cygnus, and NGC1499 the "California" emission nebula in Perseus.
The next four images are ICC5146 the "cocoon" emission nebula, NGC6888 the "crescent" emission nebula both in Cygnus, IC1805 the "heart" emission nebula in Cassiopeia and M33 spiral galaxy in Triangulum.
Below, from the left, clockwise, Paul imaged M45, the well known open Pleiades open cluster in the constellation of Taurus, M51 the "whirlpool" galaxy in Canes Venatici, NGC7000 the "North America" emission nebula in Cygnus, and IC5067/IC5070 the "pelican" emission nebula also in Cygnus. These last two emission nebulae are associated with each other, separated by dark lanes of dust and molecular gas.
Another four images all contain emission nebulae, from below left, clockwise, NGC281 the "pacman" nebula in the constellation of Cassiopeia, NGC6910 the "rocking horse" nebula in Cygnus, IC1318 plus the star Sadr (gamma Cygni) and Sharpless 2-199, the "soul" nebula in Cassiopeia.
Pauls final two images are, below left, NGC6992, part of the "veil" supernova remnant in Cygnus and to the right NGC7380, the "wizard" open cluster and nebulosity in Cepheus.
Mark Beveridge submitted six deep sky images to the section, taken with a 140mm Maksutov-Cassegrain telescope and a SXR - H814 camera plus colour filters. Below from the left, clockwise, are four images of galaxies in the constellation of Leo: M65, M95, NGC2903 and NGC3226/7, also known as Arp 94; a pair of interacting galaxies, one spiral one eliptical, about 50 million light years from the Earth.
Mark's final two images are, below left, M78 reflection nebula in the constellation of Leo, and to the right, M97 the "owl" planetary nebula in Ursa Major.
Steve Norrie sent in seven images. Steve employed an ES127mm APO f5 refractor and an Atik 920EX camera, and the first four images are M101 the "pinwheel" spiral galaxy in the constellation of Ursa Major, M1 the "crab" supernova remnant in Taurus, M51 the "whirlpool" spiral galaxy in Canes Venatici and NGC7023 the "iris" reflection nebula in Cepheus; a cloud of dust and gas being lit by a magnitude 7 star SAO19158.
Steve's three remaining images are, from below left, M42 emission nebula in the constellation of Orion, NGC2244 the "rosette" emission nebula and open cluster in Monoceros and IC434, the "horsehead" emission/dark nebula in Orion.
Eddie Carpenter made this drawing to the right of NGC2017 in the constellation of Lupus. Once thought to be an open cluster, it is now described as an asterism, a chance line of sight grouping of stars. Eddie numbered the stars in order of brightness, 1 being the brightestand 6 the faintest. He used an 8.5 inch diameter Newtonian reflector at 60x and 100x.
