SOAPBUBB.JPG
The Soap Bubble18 viewsLocated in Cygnus, this very faint planetary nebula was only discovered in 2008. Amateur astronomer Dave Jurasevich made the discovery of a lifetime on July 6th, 2008.

Circumzenithal Arc17 viewsThe Circumzenithal arc has been called "a smile in the sky" It is rarely noticed because it occurs so far overhead. Can occur when sun dogs are observed. Due to sunlight refracted from Cirrus clouds.
Picture taken hand held camera.

Dumbbell Nebula - but not as we know it!20 viewsOne of the brightest planetary nebula in the northern sky so normally short exposures are sufficient. However, to record the faint outer reaches much longer exposures are required. DRAug 22, 2010

N4565-DR.JPG
Edge-on Galaxy NGC 456526 viewsClassic edge-on galaxy in Coma Berenices. Also in the picture (particularly around the south part of NGC4565) are many very faint background galaxies. DRJul 18, 2010

The Black Eye Galaxy, M6421 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

Mosaic of the Hockey Stick and the Whale Galaxies24 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

Abell 426.jpg
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)!Jun 28, 2010

Sun30 viewsThought I would try out my new 1000D, 50-500mm Sigma & 2x teleconvertor. Image is soft at 500mm comon issue with this lens, but I am pretty happy with the resulting image, would of been nice to capture the all elusive Sun Spot tho.Jun 26, 2010
N4631-DR.JPG
The Whale Galaxy26 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
