This month five members contributed their observations to this section.\u00a0 The final tally is thirty – one digital images and two drawings.<\/p>\n

Ian Papworth<\/strong> sent in seven digital images, using a Skywatcher 150P reflector and an Altair Hypercam 183c pro colour camera\u00a0 The three below are of galaxies which lie in the constellation of Leo:\u00a0 M105 (also featuring galaxies NGC 3384 and NGC 3389), NGC 2903 and the Leo triplet: M65, M66 and NGC 3628.<\/p>\n

Ian also imaged the Perseus double cluster, NGC 884 and NGC 869, galaxy NGC 4631 known as the Whale galaxy in Canes Venatici and two globular clusters: M3 also in Canes Venatici and M13 in Hercules:<\/p>\n

\"\"
NGC 884 (left) and NGC 869 (right)<\/figcaption><\/figure>\n

NGC 4631<\/figcaption><\/figure>\n

NGC 4631 has a central region of prodigious star formation, many massive enough to end their short lives as supernovae: so many that there is a lot of material being blown out of the centre, producing a halo of X ray emitting gas around the entire galaxy.<\/p>\n

Michael Kinns,<\/strong> observing with an Orion Optics 200mm f6 Newtonian reflector at 150x and 100x magnification respectively sketched NGC 2261 Hubble’s variable nebula, a reflection nebula in the constellation of Monoceros and M78, another reflection nebula in Orion:<\/p>\n

NGC 2261<\/figcaption><\/figure>\n

M78<\/figcaption><\/figure>\n

M78 is a part of the Orion Molecular Cloud Complex and lies about 1,350 light years from the Earth.\u00a0 Two hot, bright type B stars are illuminating this nebula.<\/p>\n

 <\/p>\n

Mark Beveridge<\/strong> imaged ten galaxies –\u00a0 the first four below are all in the constellation of Leo – M96, M65, M105 and NGC 3628:<\/p>\n

M105<\/figcaption><\/figure>\n

Elliptical galaxy M105 is on the right of this image;\u00a0 the galaxy in the middle is NGC 3384 and on the left is NGC 3389.\u00a0 All belong to the Leo galaxy group.\u00a0 M105 is described as having a weak active supermassive black hole at its centre.\u00a0 M105 and NGC 3384 are surrounded by a cloud of atomic hydrogen, where star formation has been observed.<\/p>\n

NGC 3628<\/figcaption><\/figure>\n

Next are two galaxy images, NGC 2444\/5, a pair of galaxies also known as Arp143 and NGC 2683 in Lynx:<\/p>\n

Mark used a Celestron 200mm Edge HD f 10.4 SCT and a SXR \u2013 H814 mono camera plus red, green and blue filters.<\/p>\n

 <\/p>\n

David Davies<\/strong> imaged three globular clusters via an 8″ Richey Chretien telescope and a QSI 583 mono camera plus red, green and blue filters;\u00a0 M72 in the constellation of Aquarius, and NGC 6934 and NGC 7006 which are both in Delphinus:<\/p>\n

\"\"
M72<\/figcaption><\/figure>\n

M72 is in a retrograde orbit around our galaxy, possibly due to it having been captured from the Sagittarius dwarf galaxy.\u00a0 It is reckoned to be about 52,000 light years from the Earth<\/p>\n

Steve Norrie<\/strong> sent in eleven images.\u00a0 The first three below are in the constellation of Canes Venatici, M63 the Sunflower galaxy, NGC 4631 the Whale galaxy and M51 the Whirlpool galaxy:<\/p>\n

NGC 7822<\/figcaption><\/figure>\n

NGC 7822 comprises the HII emission region known as Sh2 – 171 and the young star cluster Berkley 59.\u00a0 There is a type O star within this cluster designated BD+66 1673 which is 100,000 times more luminous than the sun, having a surface temperature of around 45,000 degrees K.<\/p>\n

\"\"
M78<\/figcaption><\/figure>\n

Steve produced these images using a variety of telescopes and cameras: a Celestron 9.25 SCT, an ES 127 refractor and an Altair 80 ED-R refractor; an Atik 490 colour camera and a Starlight Xpress Trius 694 mono camera plus red, green and blue filters, also narrow band filters for the Hubble palette images of the emission nebulae above.<\/p>\n
