Solarcan image (detail)

Born from a love of photography, art & astronomy Solarcan is a unique camera designed to produce extreme time exposures that capture the Sun’s path across the sky. This image by Phil Brocklebank depicts an extreme time exposure of six months from winter to summer solstice. The full image can be seen below and technical details can be found on this page.


The Sun

This image of the sun by Pierre Grace taken on 07 March 2023 was shot through a special H-Alpha solar telescope and shows prominences and surface details such as sunspots. The camera was a ZWO ASI 174 camera and the image inverted to enhance details on the surface.  (Warning – never look at the sun with the naked eye or through optical instruments!)


The Diamond Ring, 2017 total solar eclipse

This image of the diamond ring phase of the 2017 solar eclipse was taken by Andrew Huggett in Jackson Hole, Wyoming on 21 August 2017 using a Fujifilm X-T3 mirrorless camera. (Warning – never look at the sun with the naked eye or through optical instruments!)


Lunar eclipse

Lunar eclipse photographed by Jason Woolley.


The sun’s chromosphere during the 2006 total solar eclipse

The sun’s chromosphere captured from Jalu Oasis in the Sahara Desert during the 29 March 2006 total solar eclipse. A multiple exposure captured and processed by Jason Woolley. (Warning – never look at the sun with the naked eye or through optical instruments!)


M33 (The Pinwheel Galaxy)

This photograph by Andy Hewitt depicts M33 – the Pinwheel Galaxy in the constellation of Triangulum. It was imaged from Ratlinghope, Shrewsbury and comprises of 20 x 300″ subs. Taken with a SkyWatcher 150PDS, Risingcam IMX571. Controlled and captured with NINA, processed with SiriL, Gimp and Photos.


M51 (The Whirlpool Galaxy)

M51, The Whirlpool Galaxy – imaged over 3 nights by Simon Burchill, 244 subs (mixed duration) = 9.7 hours combined in Sirilic and post processed in Siril and de-noise in Photoshop.


Lunar surface (detail) colourised

This image by Jason Woolley shows the surface of the moon colourised and enhanced to show different topographic surface details.


NGC 6888 (The Crescent Nebula)

The Crescent Nebula is an emission nebula in the constellation Cygnus, about 5000 light-years away from Earth. It was discovered by William Herschel in 1792. This image of the nebula was taken by Simon Burchill from France and comprises of 162 x 3min subs over 3 nights. Stacked in Siril using a one-click script for the Hubble pallet colours with a narrowband L-Extreme filter.


M13 (The Hercules Cluster)

M13 (The Hercules Cluster) a globular cluster photographed by Pierre Grace on the 19 April 2023. This image was taken with a Skymax 150mm scope and a Canon Ra camera. A special filter removed some of Manchester’s light pollution. The cluster comprises several hundred thousand stars and is about 24,000 light years from Earth. It can be seen with binoculars as a fuzzy patch between the stars that form the shoulders of the constellation Hercules. It contains many interesting stars and is a common target for astronomers to study. Famously, in 1974 the Arecibo observatory in Puerto Rico beamed a message which contained information about the human race, the Earth and some of our knowledge of science.


Kepler Crater

An inverted image of the Kepler Crater taken by Pierre Grace on the 26 October 2023. Taken with a Skymax 150mm scope and a using a ZWO ASI 224 camera. By stacking about 2000 images much better clarity can be achieved. This impact crater is about 32km across and 2.6km deep. It lies between the Ocean of Storms and the Sea of Islands on the moon. The ejecta can be clearly seen here and demonstrate the violence of the impact. They extend to well over 300km.
