In late March,
with the moon washing-out dimmer objects, I imaged
several clusters. This is M53, a globular cluster. 100x30s
L, 30x20s R, 30x30s G,B. |
Also M53,
taken with my new ED 80 apochromatic refractor (the
little scope mounted piggybak in the image on the home
page). Note the wider field-of-view. 50x45s L, 30x30s R,
30x45s G,B. |
The Perseus
Double Cluster - Two star clusters in one. This is
visible in binoculars. |

This is the
Beehive Cluster, taken with my ED 80. I made the spikes
on the stars by taping a couple of pieces of wire across
the front of the telescope. 30x15s L, 30x10s R, 30x15s G,B. |
This is M3,
the largest known globular cluster (there are hundreds in
our galaxy). It has about half a million stars in it and
is 30,000 light years away. 60x45s L, 20x30sR, 20x45s G,B. |
M13 - compare
it to other images I've taken of it in the past. I'm
making progress! This is the brightest of the globular
clusters, so it is a popular target. 30x60s L, 30x20s R,
30x30s G,B. |

M13, Globular
Cluster in Hercules, 10/1/06, 30x45sec, lrgb. |
M15, Globular
cluster in Pegasus, 30x20sec, lrgb. |
This isn't
really a cluster, it's a double-star - two stars orbiting
each other. Usually they look like one star and you need
a high magnification (600x here) to split them. Some
people consider them a challenge...or something. Frankly,
I don't see the point. But hey, here it is! |
