View of one of the two noon guns at Lion Battery on Signal Hill in Cape Town. The daily noon gun is Cape Town’s oldest living tradition and the two cannons used are the oldest guns in daily use in the world. They have marked the midday hour in the mother city in this distinctive, albeit noisy manner since early 1806. The cannons were cast in Britain in 1794 and still bear the royal crest of King George the third. The firing of the cannon was originally to give ships in the bay a means of re-setting their clocks accurately.

Inside Basílica de Santa María la Real de Covadonga catholic church in Cangas de Onis, Picos de Europa, Asturias, Spain, Europe. In 1777 a fire destroyed the old temple, which stood adjacent to the Holy Cave where Our Lady of Covadonga is revered. It was then decided to raise a new church as a monumental sanctuary, raising donations from all of Spain; the plan was opposed by the local council, as the canons wanted to rebuild the temple of the Holy Cave and build an ambitious sanctuary that had once been designed by Ventura Rodríguez, but never completed. One century later, the project was resumed by King Alfonso XII of Spain, who was interested in completing this work. The classic design of Ventura Rodríguez was very difficult and expensive and was replaced by a new neo-Medieval design.

NGC 7000, the North America Nebula, with the Pelican Nebula, IC 5067, at right, in Cygnus, taken from home November 21, 2016 as part of testing of the Explore Scientific FCD100 102mm apo refractor. This is a stack of 5 x 6-minute exposures at f/7 with the ES field flattener, and at ISO 1600 with the filter-modified Canon 5D MkII. Star diffraction spikes added with AstronomyTools actions.

The Very Large Array (VLA) radio telescope in New Mexico, at sunset, March 17, 2013, with the Earth shadow rising at right and the pink Belt of Venus along the eastern horizon. This is a 2-section panorama, hand-held, with the 14mm lens and Canon 60Da camera.

A demo image with the Orion 80mm CF Apo and Celestron AVX mount, with 3 x 8 minute and 3 x 6 minutes, at ISO 1600 with Canon 6D MkII plus shorter 3 x 2 minute and 3 x 1 minute exposures blended in with luminosity masks. Guided with the Orion Starshoot and Orion finderscope, using PHD2, with a lot of wild excursions in the guiding.

Astronomer Vance Petriew at the eyepiece of his 20-inch Dobsonian reflector telescope, at the 2012 Saskatchewan Summer Star Party in Cypress Hills, SK. This is a single 20 second exposure with the Canon 5DMkII at ISO 4000, and 24mm Canon L-series lens at f/2. A faint aurora adds the horizon colours. The photo was taken on the occasion of the second return of Comet Petriew 185/P since its discovery 11 years earlier in 2001 at this very same location.

One of the 27 antennas of the Very Large Array (VLA) radio telescope complex in New Mexico (with others in the distance at lower right) illuminated by moonlight, on December 13, 2013, peak night for the Geminid meteor shower. A single exposure of 30 seconds with the Rokinon 14mm lens at f/2.8 and Canon 5D MkII at ISO 800. Orion is rising a lower centre. The Moon is the bright object at upper right. The Pleiades and Hyades are above centre.

The partial eclipse of the Sun, October 23, 2014, as seen from Jasper, Alberta, shot under clear skies through a mylar filter, on the front of a 66mm f/6 apo refractor using the Canon 60Da for 1/8000 (!) sec exposure at ISO 100. The colours are natural, with the mylar filter providing a neutral 'white light' image. The big sunspot on the Sun that day is just disappearing behind the Moon's limb. The mylar filter gave a white Sun, its natural colour, but I have tinted the Sun's disk yellow for a more pleasing view that is not just white Sun/black sky.

The partial eclipse of the Sun, October 23, 2014, as seen from Jasper, Alberta, in this case shot through thin cloud but that makes for a more interesting photo than one in a clear sky. This is still shot through a mylar filter, on the front of a 66mm f/6 apo refractor using the Canon 60Da for 1/25 sec exposure at ISO 100. The colours are natural, with the mylar filter providing a neutral 'white light' image. With the Sun dimmed a lot by cloud, the longer exposure allowed picking up light and colours in the surrounding clouds.

This is the rich region in the centre of the constellation of Auriga with the Flaming Star Nebula, IC 405 at right, and the roundish IC 410 at bottom with the cluster NGC 1893. At top left is the star cluster Messier 38, with small NGC 1907 below it. The small nebula at left is IC 417 around the loose cluster Stock 8. The large elongated nebula at top is Sharpless 2-230. The colourful asterism of stars between IC 405 and IC 410 is the Leaping Minnow or Little Fish, aka Mel 31.

The Pleiades star cluster, aka Seven Sisters, or M45, in Taurus. A deep exposure showing the reflection nebulosity which fills the area. This is a stack of 5 x 14 minute exposures with the TMB 92mm apo refractor and Borg 0.85x flattener/reducer at f/4.8 and Canon 5D MkII at ISO 800. Taken from home Oct 9/10, 2013.

A telescopic closeup of Comet Lovejoy (C/2014 Q2) on January 19, 2015. I shot this from near Silver City, New Mexico, using a TMB 92mm apo refractor at f/4.4 and using a Canon 6D at ISO 1600 for a stack of 4 x 5 minute exposures. The ion tail is primarily from a single exposure to minimize blurring from the comet's motion relative to the stars. The rest of the image is from the stacked combination to minimize noise.

Harvest Moon, Sept. 27, 2004, taken from near home. With Canon Digital Rebel 300D, with 20mm lens at f/13 and 1/2 sec exposure at ISO100. Minimal processing to increase contrast but Moon image is not a fake -- the balance between sky and Moon was perfect for recording Moon detail and ground without over or underexposing either.

Comet Hartley 2 near the Pacman Nebula, NGC 281, in Cassiopeia. Stack of 4 x 6 minute exposures at ISO 1600 with Canon 5D MkII on A&M 105mm apo refractor at f/4.8 with Borg reducer/flattener. Bright star is Alpha Cas, Schedar. Autoguided with Celestron NexGuide autoguider. However, image of comet core is from only one exposure to minimize trailing from this fast-moving comet.

Sunset clouds and colours on December 3, 2013 from Massai Point, Chiricahua National Monument, Arizona. This is a 7-frame HDR High Dynamic Range stack to compress the high contrast from the bright sky and dark foreground into one image. Combined with Photomatix Pro. Taken with the Canon 5D MkIi and Canon 24mm lens at f/8. From images _MG_6996_6997_6998_6999_7000_7001_7002 taken at 2/3rd stop increments.

Omega Centauri globular cluster, with Canon 20Da camera with 4-inch Astro-Physics Traveler apo refractor at f/6 for 4 minutes each at ISO800. Stack of 4 exposures, averaged stacked. Plus short 2-minute exposure for core area. Taken from Queensland, Australia, July 2006.

The area of the Rosette Nebula (bottom) and Christmas Tree Cluster (top) in Monoceros with the Fornax Lightrack tracker and 200mm lens + Canon 5D MkII. The nebulosity at top includes the Cone Nebula.

A session shooting deep-sky objects in the rural backyard in Alberta, on a chilly November night, November 8, 2018. I was using the Celestron 8 HD tube assembly on the Astro-Physics Mach One mount, and was shooting Messier 27 with the Canon 6 D MkII. I shot this image with the Sony a7III and Venus Optics 15mm lens at f/2 focused on the foreground.

Gum Nebula area of Vela and Puppis. Taken from Atacama Lodge, Chile, March 19, 2010, with modified Canon 5D MkII and Sigma 50mm lens at f/4, for stack of 10 x 6 minute exposures (Mean combined) at ISO 800 plus 2 x 6 minutes with Kenko Softon filter. High contrast boost and Selective Colour adjustments to bring out nebulocity while retaining neutral sky.

Nebulosity in the heart of Cygnus the Swan, including the North America Nebula and Pelican Nebula at left (NGC 7000 and IC 5070) and Gamma Cygni complex at right (IC 1318). The Crescent Nebula (NGC 6888) is at lower right. This is a stack of 5 x 4 minute exposures at f/2 with the 135mm lens and modified Canon 5D MkII at ISO 800, plus another three similar exposure images but taken thru the Kenko Softon filter for the star glows. Taken from home Sept 10, 2013.

9-day-old gibbous Moon, taken April 23, 2010, with Astro-Physics 130mm apo refractor, plus 2x Barlow for f/12 and 1600mm focal length. Canon 7D camera at ISO 100. Seeing poor -- this was the sharpest of the lot.
