Centaurus A thumbnail
Centaurus A is a peculiar galaxy discovered in 1826 by Scottish astronomer James Dunlop in Parramatta, Australia. It is ~10-16 million light years away and its lenticular with dust lanes hybrid appearance is the result of a merge of two galaxies.

Omega Centauri thumbnail
Omega Centauri (NGC 5139) is the largest globular cluster in the Milky Way at a diameter of roughly 150 light-years. It is estimated to contain approximately 10 million stars.

Spiral Galaxy Caldwell 101 thumbnail
Caldwell 101 is a spiral galaxy about 31 million light-years away, tilted towards our line of sight. It is thought to be one of the most Milky Way-like spiral galaxies in our immediate vicinity. It also has at least one distorted companion galaxy similar to the Magellanic Clouds.

Caldwell 68 and Globular Cluster NGC6723 thumbnail
Less than 500 light-years away and blocking light from more distant, background stars in the Milky Way, the densest part of the dust cloud of Caldwell 68 is about 8 light-years long. At its tip is a group of reflection nebulae cataloged as NGC 6726, 6727, 6729, and IC 4812. A characteristic blue color is produced as light from hot stars is reflected by the cosmic dust.

Colliding Antennae Galaxies thumbnail
The Antennae Galaxies, also known as NGC 4038/NGC 4039, are a pair of interacting galaxies ~45 million light years away. They are currently going through a starburst phase, in which the collision of clouds of gas and dust, with entangled magnetic fields, causes rapid star formation.

Asteroid 2000 JU23 Passing the Antennae Galaxies NGC 4038 / NGC 4039 thumbnail
While looking through the data captured of the Antennae galaxies, I discovered a very dim object slowly moving through the field of view. I have identified the object as main belt asteroid 2000 JU23, magnitude 18.8

Globular Cluster Caldwell 79 / NGC 3201 thumbnail
It's been cloudy. Very cloudy. I managed to get a short imaging session, so I had to choose a bright target. The globular cluster Caldwell 79 was in the right place at the right time. It is located at a distance of 16,300 light years from the Sun and has an estimated 254,000 times the mass of the Sun. This cluster is about 10.24 billion years old.

Animation of NGC 300 Processing Stages thumbnail
Often I like to see how an image is processed from start to finished. Presented in this animation are the main processing steps in sequence from my image of NGC 300

NGC 300 thumbnail
NGC 300 is a spiral galaxy in the constellation Sculptor. It is one of the closest galaxies to the Local Group at 6 million light years distance.

Test Shot of the Sculptor Galaxy thumbnail
I was playing around with my camera binning modes in preparation for a dark sky trip next weekend, and ended up with this. Even though it's just a test shot, I think it turned out pretty well. New lesson learned; don't overexpose the stars.
