Globular cluster Messier 13
Up till now I wasn't able to make a decent picture of a globular cluster. Last night I amed the telescope at The Great Globular Cluster in Hercules. This picture consists of 50 frames. The exposure time is 30 seconds at 1600 ISO. I stacked the frames with DeepSkyStacker and touched it up a little with Photoshop.

The Orion nebulae
Last night was very clear. A good moment to capture the M42. This birthplace for stars can be found in the constelation of Orion. From my observatory, the nebulae bearly rises above the tree tops. So its a matter of good timing to get a good shot. In this picture I used 40 frames of 30 seconds each. The camera was set to ISO 1600. I used Deepskystacker to stack the frames, and used Photoshop and Nebulosity to finalse it.

Erupting comet Holmes
Comet Holmes, normaly an object unvisible to the nacked eye, erupted this week. These photo's where taken today. The white center of the picture reveals the dust tail of the comet. The green halo is the gas tail. Because the sun is "behind" the observer, dust and gastail are in line. Thats why this comet lookes so odd. The picture with the halo consists of 100 frames 0f 30 seconds each on ISO 1600. The dust tail picture is made of 20 frames of 15 seconds each on ISO 800. It was hard to capture the core of the comet. It was easely overexposed! Eager to find the comet yourself?
Data for 30-10-2007:
Comet '17P' Magnitude= 2.9. Best seen from 17.7h - 6.8h. RA= 3h47m26 Dec=+50°29.0' (J2000) Distance to Sun= 2.46AU Distance to Earth= 1.62AU Elongation=139° hourly motion: dRA=-24.9"/h dDec= 6.5"/h.

The moon is getting sharper

These two pictures are taken on august the 5th. In the early morning hours the sky was very clear and there wasn't much seeing. And als the collimation of the scope wasn't that bad. So the circumstances were good to make sharp pictures. These photo's of the moon (last quarter) are the sharpest yet. For the photo of the crater Copernicus, I used 3 frames that are combined in photoshop.

M51: Resampled
While testing my new laptop I resampled my picture of M51 (Canes Venatici). I also detected that two other little galaxy's are visible: IC 4263 (Mvis 15,7) and NGC 5169 (Mvis 14.4). These galaxy's are found at the right hand corner, below the middle. Can you find them? Never before I photographed objects this dimm.The tests revealed that Microsoft Vista causes a lot of driver problems. I need to solve them before my holiday in Southern France. I take the telescope, the camera an the laptop along. Time is ticking.....
