SS-01Petavius crater Petavius is one of the large impact craters that make up the “Gang of Four”. Petavius, located on the southeast side of the Moon, is 177 kilometers wide. Petavius has a prominent central mountain massif, extensively terraced walls, and an external network of ridges and furrows. Sinuous rilles extend across the crater’s floor, the most impressive of which is Rimae Petavius, which runs in a more or less straight line from the central mountains to the southwestern inner wall of Petavius. Rima Petavius, a fault feature formed by crustal tension, gives Petavius the appearance of a clock face with its hour hand at the 8 o’clock position. Captured at 9:13 pm on 20 November 2021 at Halifax, NS. Equipment consisted of a Celestron C8 200mm f/10 Schmidt-Cassegrain telescope with a 2X Barlow, SkyWatcher EQ6R Pro mount, and a ZWO ASI290MM CMOS camera (gain 200, 0.78-millisecond exposures, MONO16/SER format) with an IR 850nm pass filter at prime focus. SharpCap was used to capture 1005 frames of video. The best 10% of video frames were selected and stacked with AutoStakkert 3. Registax 6 was used for wavelets. Levels, sharpness, contrast, highlights and shadows were tweaked using Photoshop CS2 and Microsoft Photo.SS-02Total solar eclipse photo montage This is a montage of photographs obtained during the 8 April 2024 solar eclipse, from beginning to end.

Equipment consisted of a Canon T3i DSLR on manual with a Canon 50-250mm lens fitted with a solar filter, all mounted on a SkyWatcher Star Adventurer tracking mount. Exposures at 250mm, f/8, ISO-100 ranged from 1/800 second to 1/50 second, depending on the phase of the eclipse. Images were captured in RAW format and converted to TIFF format using Canon’s Digital Photo Professional. False color was added to images of the partial phase using Photoshop.SS-03Moon from Urban HalifaxThis photo taken of the moon was taken in light polluted Fairview in Halifax NS in October 2024 after long period of not doing any astrophotography. I was gifted a lovely smart telescope. The S50 mainly helps with my mobility issues and also my time management as I don’t have to set up the scope for 30 minutes before hand and I can do it all early on in the evening so I actually have time to enjoy this wonderful hobby.
