THE PROCESS BEHIND THE PHOTOGRAPHS
Field notes.
Existing imaging notes, equipment details and processing stories, in the photographer’s own words.
↗27-Apr-2017Rho Ophiuchi
IC4603 and IC4604 Showing Rho Ophiuchi Color Transition
Inside the Rho Ophiuchi cloud complex live the star clusters IC4604 (left) and IC4603 (right). Heading towards the bottom of the image shows the transition from blue reflection nebulae to red emission nebulae.

NGC 2835 Spiral Galaxy
NGC2835 is a small, faint spiral galaxy in the Hydra constellation. It was probably too small and faint to attempt from the suburbs of Brisbane, but I persisted through the very few clear nights I could get ove

Omega Centauri
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.

Comet C/2015 ER61 Nears Earth
C/2015 ER61 is a comet from the inner Oort cloud approximately 8-20 metres in diameter. By April 19th 2017 it will reach its closest point to Earth, and on May 10th it will reach its closest point to the Sun. I

Comet C/2015 ER61 Motion
Comets move fast. So fast that you cannot use stars to guide your telescope. With an on-axis guider I was able to lock the telescope on to the fuzzy comet. This animation shows how fast the comet moves over a 3

↗02-Dec-2016Nebula
The Orion Nebula
The Orion Nebula is one of the brightest nebulae in the sky, visible to the naked eye. It is seen as the fuzzy middle star in the sword of Orion. The nebula is 1344 light years away and is one of the closest st

↗16-Aug-2016Helix Nebula
Narrowband Helix Nebula
I've already done the Helix Nebula in natural colour, so I've imaged it again in narrowband. Lots of H-alpha and Oxygen-III, but barely any Sulfur-II.

On the Shoreline of the Lagoon
Next to the Lagoon Nebula, there lies the often overlooked collection of absorption, reflection and emission nebulae: NGC 6559, IC 1274, IC 1275, IC 4684, IC 4685, Barnard 303, LDN 227, LDN 213, and planetary n

↗03-Aug-2016Trifid Nebula
Trifid Nebula in HaLRGB
Almost everyone has a go at imaging the Trifid nebula, which is composed of 3 different type of nebulae; emission, reflection, and absorption. When I noticed some faint red glow in the background, I decided to

Spiral Galaxy Caldwell 101
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

↗26-Jun-2016Reflection Nebula
Caldwell 68 and Globular Cluster NGC6723
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 re

Revisiting the Lagoon Nebula with a new telescope.
I was lucky enough to snag a second hand 900mm refractor at a good price. I needed a bright target to test it with. The Lagoon Nebula is a giant interstellar cloud around 4077 light years away, classified as an

NGC6357 in Narrowband
NGC 6357 is a diffuse nebula in the constellation Scorpius. The nebula contains many proto-stars shielded by dark disks of gas, and young stars wrapped in expanding gases. It is also known as the Lobster Nebula
