Sky & Telescope - February 2024 - 33

you'll land on a trio of galaxies - two of which, NGC 2292
and NGC 2293, are merging. They're a delightful, compact
sight, both 11th magnitude, and once you've located them
they take high power (e.g., 300×) well.
Head southwest and pop into Columba to visit a very nice,
large globular cluster. NGC 1851, at magnitude 7.1, is a pleasing
sight in a moderate-power (60-100×) eyepiece, and with
its dense inner core it resembles a smaller version of the globular
M3 in Canes Venatici. From 2.6-magnitude Alpha Columbae,
head just a bit shy of 8° southwest to find your target.
Back in Canis Major we'll move on to a treat: the diffuse
NGC 1365
nebula NGC 2359, also known as Thor's Helmet. To find it,
you can either slide 8.7° northeast of Sirius or 6° east-southeast
of 4th-magnitude Theta (θ) Canis Majoris, the celestial
Dog's nose. This is a stunning sight if you employ an O III
filter and a beautiful object to behold. It's a bright emission
nebula powered by a massive Wolf-Rayet star (see, e.g., S&T:
Aug. 2019, p. 28) - strong stellar winds sculpted and distorted
the nebula into the shape as seen on page 35. I suggest
low-power views in your 8-inch telescope.
Puppis holds our next quarry, which is the delightful
open cluster M46 (NGC 2437) that has the planetary nebula
NGC 2438 superposed on it. Use a wide-field eyepiece for the
NGC 1300
BARRED SPIRALS Among the author's favorite targets, galaxies
feature prominently in his observing, as he himself admits. These two
barred specimens - NGC 1365 in Fornax and NGC 1300 in neighboring
Eridanus - are sights to behold. They are pleasing in any size telescope,
but in dark skies with a 14-inch or larger, you'll start noticing the beautiful
detail of the spiral arms and the knots of hydrogen-alpha regions.
