30 Galaxies in one image?22 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 119 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 M10618 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

Split Personality, M6320 viewsBright spiral galaxy located in Canes Venatici. It is a classic flocculent type of spiral, ie one where its visual appearance has short dis-jointed spiral structure. However, studies of molecular gas in the galaxy reveal long symmetrical spiral arms - a case of split personality! DR.

The Black Eye Galaxy, M6420 viewsLast of my spring images - the observatory is currently shut for 3 months during the summer light nights.
A collision of two galaxies has created this unusual galaxy with a spectacular dark band of absorbing dust in front of the galaxy's bright nucleus, giving rise to its popular name of the "Black Eye" galaxy. A famous HST image reveals the dark band in all its glory but we get a hint of its turbulent motion here. DR

Two for the price of one!20 viewsPair of bright 9th magnitudes galaxies in the tail of Leo discovered by Messier in 1780. M65 (right) is the slightly nearer galaxy at 22 million light-years with M66 (left) further away at 36 Mly. DR.
