30 Galaxies in one image?17 viewsAt this quiet time of year for astronomy I was looking back over previous images and came across one of my very dull and boring galaxy library photos. The galaxy I was imaging is part of the Abell 426 Galaxy Cluster. I wondered how many galaxies were caught in this image in total so I used "The Sky" software to generate a chart of the exact area and then "switched off" all the stars (an option in the software) to leave only the Galaxies behind. The image on the left is my original 60 second image (March 8th 2010) - the one in the centre is not an image but the corresponding chart and the one on the right is the chart showing galaxies only. Most of these galaxies can be seen in the original "boring" image and I estimate I captured over 30 galaxies in that single image - perhaps making it a little less boring! In addition one of these galaxies - NGC 1275 - is also known as C24 and is of particular interest. To find out why go to Page 62 of a book by the well known author- David Ratledge -"Observing the Caldwell Objects" (Caldwell C24)!

Planetary Nebula Jones-Emberson 118 viewsLarge but very faint planetary nebula in Lynx discovered in 1939 but the discovery report mis-identified it as NGC 2474/5. Unfortunately this error has been oft repeated resulting in some planetarium programs, eg SkyMap, not including this object. It is in fact about 1 degree north of the galaxy pair NGC 2474/5.

Spiral Galaxy M10615 viewsDiscovered by Pierre Méchain in 1781, M106 is a large bright galaxy located in Canes Venatici. It is one of the closest Seyfert galaxies to us at around 25 million light-years away. Seyfert galaxies have active galactic nuclei thought to powered by supermassive black holes at their centre - sort of a tame quasar! The companion galaxy is NGC 4217. DR

Spiral Galaxy NGC 268320 viewsLocated in Lynx, this almost edge-on galaxy was discovered by William Herschel in 1788. A feature of this galaxy is the mottled dust patches on the near side to us. Distance estimates vary from 16 to 25 million light years.

Seyfert Galaxy NGC 415113 viewsAlthough the observatory is now enjoying its summer break there is still a backlog of images to process. NGC 4151 was one of the first Seyfert Galaxies to be discovered. The Seyferts are characterised by active galactic nuclei (AGN) which are very bright both in the optical and X-ray bands together with broad emission lines. They are powered by black holes at their centres and are believed to be similar to quasars but of somewhat lower energy. DR

Edge-on Galaxy NGC 456513 viewsClassic edge-on galaxy in Coma Berenices. Also in the picture (particularly around the south part of NGC4565) are many very faint background galaxies. DR

The Whale Galaxy17 viewsTwo years in the making! Data from 2009 and 2010 combined to produce this image.
Starburst galaxy without the normal smoothness of a typical edge-on galaxy. Its turbulent form is thought to be due to a previous interaction with nearby galaxy NGC 4656 (out of picture). DR

Mosaic of the Hockey Stick and the Whale Galaxies14 viewsI've got a bit behind with my processing - blame the World Cup but now that it is over I can get back to business!
Four panel mosaic of the NGC 4631 Galaxy Group. The two main galaxies are highly disturbed and NGC 4631 (left) also has faint extensions - if you look carefully. DR
