C/2006 VZ13 (LINEAR)12 viewsI've aligned all the images on the comet, so the background stars appear to move across the frame. You'll see that I wasn't imaging continuously, but in three bursts, over the course of 40 minutes.

C/2007 F1 LONEOS10 viewsThis is one of my first astro-images with the Pentax DSLR. The comet was low in the West, so I had to set up the camera and mount outside my front door, under the glare of the street-lights!

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)!

Asteroid passing near M74 - 15 Nov 200952 viewsAn image of mine taken between 6:15pm and 9:20pm on 15th Nov 2009 revealed an asteroid near M74. The movement of the asteroid during the 3 hours produced the trail. Judging by its brightness (16th mag approx) it must be a known one but as yet I haven't been able to identify it. DR

22 viewsComet McNaught Animation – the comet moved as shown through Cepheus in the early hours of Thursday 13th May 2010. (Click to run) A series of 45 second images were taken and 23 of these were used to form the animation. (I used every 5th image from the sequence). The time of the first frame was 01:12 U.T. and the 23rd frame was 02:39 U.T. so the comet moved the distance shown (towards the North East) in 87 minutes. The scale of the square image is 11.4 minutes of arc on each side, giving an estimated 4 minutes of arc of movement of the comet giving a speed of 2.7 arc seconds per minute. I had to stop because the sky was brightening as it was actually beginning to get light! (3.39 am BST).
