Another image I've been meaning to clean up. I was initially going for a 30-minute exposure to capture the comet's proper motion, but after about 5 minutes a beautifully bright sporadic meteor blazed right through the frame and I decided to play it safe and end the exposure.

M44, also known as the Beehive Cluster, is an open cluster of stars in the heart of the constellation of Cancer. It is approximately 600 ly from Earth and contains more than 200 stars.


Imaging equipment: Sky-Watcher 80ED (f/7.5), HEQ5 mount, Canon EOS 40D at prime focus, Astronomik CLS filter. Guiding equipment: Sky-Watcher 100ED, StarShoot Autoguider. Total imaging time 93 minutes. Sets of 5- and 6-minute sub-frames (taken in February 2011 from Elgin, Scotland) were processed and stacked in Photoshop - utilising ProDigital Software's Astronomy plug-ins and StarSpikes Pro.

Update 2012 09 20: I am delighted that this image was HIGHLY COMMENDED in the 2012 Astronomy Photographer of the Year Competition. It is now in the Exhibition at the Royal Greenwich Observatory and appears in the book of the event.


This comet is still going strong (2012 March). High up for northern observers, in UMa. You can get a chart here.

Software: GRIP (

The brightest star is HIP 54721, 11 12 10.9 +68 16 18.7, mV = 6.40


I did not track the comet directly. My equatorial mount simply did its usual thing of driving at sidereal rate (ie, star rate, compensating for the rotation of the Earth). The comet does not move perceptibly in each individual half-minute exposure. But between the first and last of the 65 exposures the motion of the comet against the stars was significant, as is evident in my image.

The key is software. I have written the stacking part of my GRIP application so that for comets and asteroids the object of interest can be held still in the stacked result.

Trying to get more red..

Enough on this.... as it is really hitting the tree tops...keeping me up a bit.(!)

Glad I got it at all...

Bit of a lapse before more NB targets float along....

Time to bear down on finding a good (ie a compromise) dark site for some tests..

The telescope was poorly collimated, and I'm not totally convinced on the focus, but I was too eager to actually use it, having had it for a couple of months.
