September 2015

A busy month for Deep Sky Section;  7 members sent in their drawings and images, 28 observations in total. 

David Davies, using an ED120 refractor and a QSI 583 camera plus a Lodestar off axis guider to capture deep images of M27, the "dumbbell" planetary nebula in Vulpecula (below left) and NGC7023 (Caldwell 4) in Cepheus; the "Iris" reflection nebula, near to T Cephei, (a Mira-type variable star).

                                                                                               

                                                                                            

Ian Papworth sent in 10 images this month, taken via a Celestron Nexstar 6SE f6.3 Schmidt-Cassegrain telescope and a ZWO ASI 120MM camera.  The first four, below, are globular clusters;  in a clockwise direction they are M2 (Aquarius), M15 (Pegasus), M92 (Hercules) and M56 (Lyra).                                                                                              

                                                                              

          

Ian also imaged the double star Albireo, (beta Cygni), and other double stars zeta Lyrae, 61 Cygni, 17 Cygni, Epsilon Lyrae and gamma Andromedae (all below).                                   

                                                                                                     

                             

                                                                                                                                       

Michael Kinns, using a 200mm f6 Newtonian telescope, observed and drew open clusters NGC6755 (below left) and NGC6756 (below right), both in the constellation of Aquila.                                                                                                                                                                                                                               

Michael also drew globular clusters NGC6934 (Delphinus, below left) and M92, (Hercules, below right)                                                                                        

Peter Clark drew globular cluster M5 (Serpens Caput, below) using his 8" f6 Newtonian telescope plus various eyepieces to give magnifications of 150x, 299x, and 360x.                                         

                                                                                                         

Graham Taylor, using the Bradford Remote Telescope, (a Celestron C14 f11 SCT on the island of Teneriffe), imaged two galaxies;  M31 in the constellation of Andromeda and NGC7331 in Pegasus;  and two planetary nebualae, M27 (Vulpecula) and M57 (the "ring" nebula, Lyra) - in that order clockwise below:

               

                                                                                            

Steve Norrie sent in two images of emission nebulae:  NGC7538 (below left) in the constellation of Cepheus, and NGC7635, the "bubble" nebula in Cassiopeia; the open cluster M52 also teatures in this image (below, right).  Steve observes with an EDR80 refractor and an astro-modified Canon 600DDSLR.

       

Mike Wood made two sketches using a Celestron C9.25 Schmidt Cassegrain telescope;  Altair and its surrounding starfield (Aquila, below left), and AC Andromedae, an RR Lyrae type star (below right).

       

Mike also used a 20" Dobsonian reflector to observe and sketch three planetary nebulae in Aquila, from the left below, NGC6751, NGC6781 and NGC6804.
