I'm an astro, landscape and wildlife photographer from Bristol. If I'm outside I'm happy!

Another image from my wild camp on Dartmoor this week.
Canon EOS R with Samyang 24mm f1.4.
Untracked, shot at f2, ISO 6400. Two shot 'Verterama'

Isolated lightning storm, a giant lightsaber, stars, and setting moon.
That's what you get on fabulous Dartmoor on a wild camp! 😅
(Oh and transpires quite a lot of ticks to dig out, but some things are worth it..)
Single exposure, 13 seconds, ISO 6400, f2.

Progress! This year's version of the Needle Galaxy...

What you're looking at is a distant (30-50 million light years away) aligned perfectly edge on to our view 🤯

10 hrs of exposures from my garden in Bristol.

1:1 resolution, (1350 px) only occupies a small part of the frame despite my almost 1m focal length.

The beautiful Rho Ophiuchi cloud complex, one of my favorite regions of the night sky!
You can find this by following the pointing front legs of the Dark Horse Nebula in the milky way core to Antares, the bright yellow star middle lower. Also the globular start cluster M4 can be seen. The region is one of the closest start forming regions to us at just 460 light years. The dark streaks are areas of interstellar dust hiding the stars behind.
This is a reprocess, with much better skills on my part, of some old data, just 20 mins of exposure from a dark site. (Canon 80D, Canon 100mm L macro lens, Fornax Lightrack 2 tracker, Benro Mach 3 tripod. f2.8, ISO1600, 240 seconds x 5)

I spent a cracking night with Gregg Wyber at Winspit Quarry Tuesday night to capture the Milky Way from one of the caves...

One I've never imaged before- M63, the Sunflower Galaxy!
This one's quite far away- 30,000,000 light years! As such, it's pretty small in each exposure, being only 500 pixels across, so perfect focus and guiding was a must.
It's thought to contain 400 billion stars. It's tightly-wrapped arms extend 13,000 LY from its nucleus.
9 hrs of unfiltered 2-min exposures from the garden here in Bristol, at 940mm focal length, (Technosky 125mm APO refractor), imaging with a crop-frame Canon EOS 80D DSLR, sat on a Skywatcher AZ-EQ6 GT Pro mount and ASIAIR combo.

My latest & greatest images of these two galaxies, M82, AKA Cigar Galaxy, and M81, Bodes Galaxy, which both fit in a single frame at 1000mm focal length.
The Cigar Galaxy is one of my favourites- due to the starburst region in the middle, thousands of light years across, accentuated here using a Hydrogen Alpha filter hence the red colour.
A total of 20hrs of exposure time, 10 broadband, 10 narrow-band, imaged from the garden here in Bristol.

The Bubble Nebula, dual-filter version, adding a real feeling of depth to the image by differentiating the emmision gases by colour.
A heavy image crop of what is an apparently small (small angular size when viewed from earth, fractions of a degree across) object- The Bubble part itself is around ten light years across, big enough to house our extended solar system (including the Ort Cloud) three times over! 🤯

Orion battling the intense full Moon on the frosty Mendips.

My first time exploring the fantastic miny crags and sumps of Ubley Warren last night, with the incredibly bright moonlight, headtorch was optional!

Though a beautiful area, composition was a challenge, as was the intensity of the moonlight. By literally resting the camera on the ground the sparkling frost gave me a leading line to the skeletal tree with orion peeking through the branches.

My latest rendition of the Cosmic Skull! Now includes 12hrs of data captured over the past couple of years.

The Rosette Nebula (NGC 2237) is a large, circular star-forming region about 5,000 light-years away in the constellation Monoceros, known for its flower-like shape with a central open star cluster (NGC 2244). Intense ultraviolet radiation from the young stars in the cluster illuminates the surrounding hydrogen gas, causing it to glow red, while stellar winds carve out the central cavity, triggering further star formation in dense clouds. It's a massive nebula, over 100 light-years in diameter.
