Bill Batchelor’s image of a supernova remnant and SH2-216 won Photo of the Week for the period of Jan. 7-13, 2023.
In his submission, he said the image provided an “interesting field of view that captures the death of two stars in different ways. SH2-221 is a huge supernova remnant, and SH2-216 is a large and ancient planetary nebula.”
“Lots of good stuff,” said the judges. “Nice capture.”
The photo was taken during several image sessions in November 2022 in Coquitlam, British Columbia, with a Canon EF 200mm F/2.8 II USM, an ASI1600MM Pro, and Astrodon 5nm NB Filters (Ha, OIII, SII) / Astrodon Tru-Balance 2E series LRGB filters. Total exposure time was 30.5 hours.
Malcolm Loro’s image of the Moon received an honourable mention for the same period. “This area, within and between Mare Imbrium (Sea of Rains) — and Mare Frigoris (Sea of Cold) — both large lava plains, is loaded with fascinating features,” he wrote in his submission letter.
“Plato is on the northern edge with its multiple small craterlets,” he added. “Next to Plato, the Montes Alps are bisected by the Alpine Valley (Vallis Alpes). Below this is lava-flooded Cassini — a very old crater from before Mare Imbrium was formed.”
Judges said the image offers “nice detail and contrast” and a “great narrative to help.”
“For the youth category, this is well done. Nice and sharp, really good contrast, and an interesting area of the lunar surface,” they said.
The image was taken on or around December 13, 2022 from Loro’s backyard patio in Kanata, Ontario, with an ASI533MC Pro colour camera and a Celestron C9.25 SCT with TeleVue Powermate 2.5. Exposure time involved a stack of 300 images of about 6 minutes each.
