BEST DEEP-SKY IMAGE
The deep-sky category was by far the most competitive
in this year’s contest. We had dozens of superb entries.
In the end, this impressive narrowband portrait of
the Rosette Nebula garnered a couple votes more than
the runner-up (left). Stephan Hamel of Hanwell, New
Brunswick, recorded a total of 11 hours of exposure data
with a ZWO ASI1600MM Pro monochromatic imaging
camera, an Explore Scientific 80mm refractor telescope
and a filter set consisting of an Astronomik 6nm O-III, an
Optolong 12nm H-alpha and a Baader Planetarium S-II.Honourable Mention Some astrophotographers
stray off the beaten path to record objects that may not
be immediately recognizable, such as the fancifully named
Jellyfish Nebula (IC443), which dominates the lower right
portion of the photo. The Jellyfish is a supernova remnant
in Gemini, located near the western foot of the twins. To
produce this image, astrophotographer Grzegorz Gurdak
of Mississauga, Ontario, acquired 21 hours of exposure
using a ZWO ASI1600MM Pro monochromatic imaging
camera and a Tele Vue NP101is apochromatic refractor
telescope with H-alpha and O-III filters.
