Another look at the “green comet”
I don’t know why the press has latched onto the name “the green comet” for C/2022 E3 (ZTF) – most comets are green, and it’s too dim to see any color at all if you’re viewing it through binoculars or a telescope. But through 2 hours of total exposure time, the colors do emerge, and…
A bunch of obscure galaxies in Virgo (NGC5364 and friends)
There’s a big cluster of galaxies within Virgo; it’s just filthy with them. People usually image a different part of it, but I found another interesting area that’s often overlooked. The grand-design spiral at the bottom is NGC5364; it’s about 55 million light-years away. The annotated image identifies its buddies.
Off to See the Wizard (again)
These past couple of nights, I revisited the Wizard Nebula – home of a star cluster about 7,000 light-years away within the constellation Cepheus. This is a false-color image in the “Hubble Palette” where red, green, and blue represent ionized Sulphur, Hydrogen, and Oxygen emissions respectively. Can you see the “wizard”? Hint: he’s lying on…
Just an obscure little cloud of hydrogen.
This nebula goes by the unassuming name of SH2-9. It’s part of a larger complex of clouds known as the Rho Ophiuchi complex, but you don’t often see people focusing on this part of it. It’s a challenge to image from my location, as it’s very low in the sky in a light-polluted direction. There…
The Leo Trio (again)
It’s been awhile since I imaged the “Leo Trio” (aka Leo Triplet) of galaxies: M65, M66, and NGC 3628. I wanted to see if my latest equipment, software, and somewhat darker skies made a difference. I’d say so… this is a total of 25 hours of exposure time, including some Hydrogen-alpha filter data to pull…
Bode’s Galaxies (M81 & M82)
Johan Bode discovered both Bode’s Galaxy (M81, on the left) and the Cigar Galaxy (M82, on the right.) Look closely and you’ll see many other, more distant galaxies in the background as well.
