December 2015

This month most of the observations sent to the Deep Sky Section were from members located in Scotland (as were all of the obsevations in November 2015 as it happens - an indication of the dearth of clear skies in the rest of the UK this winter so far.)

Steve Norrie, observing from Fife, sent in 6 images, the first two using an EDR 80 refractor, the remainder using an Explore Scientific 127mm f7.5 APO refractor:  the camera employed was an astro modified Canon 600D DSLR.

Clockwise from the left below are M81 and M82 galaxies in the constellation of Ursa Major, NGC7635 an emission nebula in Cassiopeia (known as the "bubble" nebula:  note open cluster M52 is in this wide angle image), M33 galaxy in Triangulum and M74 galaxy in Pisces.  M82, also known as the cigar galaxy, is experiencing starburst activity most likely due to its interaction with M81 (Bode's galaxy).




Steve's final two images, below from the left, are M81 in Ursa Major, and another image of NGC7635, the "bubble emission nebula in Cassiopeia.                                                                                                                                                                                                                                                                                                                                      


Mark Beveridge, observing from Aberdeen, sent in 12 images, all taken with a 140mm f 14.3 OMC Maksutov - Cassegrain telescope and SXR - H14 mono camera plus RGB filters.  The first four, clockwise from the left below, are M38, open cluster in the constellation of Auriga, M36 another open cluster also in Auriga,  NGC2276 and 2300 galaxies in Cepheus; the former (up and right of centre) an interesting object that has recently been found to have an intermediate black hole in one of its spiral arms , and NGC2768, an elliptical galxy in Ursa Major, which is a Seyfert galaxy containing an active supermassive black hole.


Mark's next four images, from the left, are NGC6995, part of the Eastern Veil nebula in the constellation of Cygnus, IC5070 the "pelican" nebula, also in Cygnus, M33 galaxy in Triangulum and NGC7331 galaxy in Pegasus.                                                                              


                                                                                     Mark's final four images are, from the left below in a clockwise direction, NGC48, a barred spiral galaxy in the constellation of Andromeda, NGC185, a dwarf spheroidal galaxy in Cassiopeia, NGC7640, another barred spiral galaxy in Andromeda, and NGC281, the "pacman" emision nebula in Cassiopeia.

NGC48 is just to the right of centre in this image. There are several other faint galaxies seen here too;  above NGC48 is IC1535 and to the right lenticular galaxy NGC49 and spiral galaxy NGC51.                                                                                                          


Alan Clitherow, SPA Planetary Section Director and also observing from Fife, sent in three images.  The first was taken with a Williams Optics 66mm refractor working at about f5, the remainder with a MN190P f5.3 Maksutov-Newtonian telescope, all using a QHY10 colour camera.   

From the left below, IC1396 the "elephant's trunk" emision nebula in the constellation of Cepheus, M33 galaxy in Triangulum and NGC6888, the "crescent" emision nebula in Cygnus, energised by energetic Wolf Reyet star WR 136.  IC1396 is a site of new star formation, possibly some are as young as 100,000 years.                                                                                                                                                                                   




Ian Papworth, SPA membership secretary, sent in a comprehensive study of M1, the "crab" supernova remnant in Taurus.

As well as a black and white luminance image ( below left) he made 4 further images:  in a clockwise direction - M1 negative, using an OIII filter, using a  H alpha filter, and finally, bottom left, an image combining the data from the two fitered images. 

Ian used a Celestron Nexstar 6SE f6.3 SCT and a ZWO ASI MM camera.
