Comet Holmes is making news in astronomy circles, with a sudden burst increasing its brightness several thousand times and makng it visible to the naked eye. Sites like spaceweather.com are featuring extra-ordinary photos of this comet with extra-ordinary cameras and dedicated astronomy ameteurs/professionals. With my very modest FZ3 and a limited 8 second exposure (I saw a photo with an exposure of 2 hours!!), I was able to capture these two images.

This image shows the comet and the Pleiades cluster adorning the sides of a palm tree.

While these wide angle shots show the comet just as a star, the comet actually looks a little fuzzy and through a telescope or even a good pair of binoculars, it looks quite big like a tennis ball with a halo around it.

Thanks Rafael. Those two images were without zoom. The following shots of the Pleiades cluster were taken with zoom:

This was half-way, about 6-7x:

These are quite nice. It is good you labeled them as I for one would never have figured it out. That two hour exposure you mention; I wonder how they keep the camera pointing at the target that long.

They must have sophisticated tracking equipment, otherwise it is not possible to keep the object focused.

Actually the equipment is not THAT sophisticated. Plenty of motorized telescope mounts around for amateus. All it really needs to do is work out where it is and where it is pointing, the movement of the earth is known and that would be the main movement to keep track of. Once you have that you just bolt your camera to it.

Easy!

Of course I say that having never done it, but the theory is easy enough.
