Inspired by JWST I imaged Neptune and Triton on Wednesday night. My best capture to date, so I'm pretty happy about that. I love being able to turn my backyard scope to the same targets as professionals.

M86 is an elliptical galaxy located about 52 Mly away in the constellation Virgo.

NGC 6822 Barnard's Galaxy

Magnitude 9.3 barred irregular galaxy located 1.63 million light-years away in the constellation Sagittarius. It was discovered by E. E. Barnard in 1884 with a 6-inch refractor telescope. Edwin Hubble detected 11 Cepheid variable stars in this galaxy which helped him determine its distance and conclude that it lies far beyond the Milky Way, settling the debate at the time about the size of the universe.

So this happened today...

I'm listed as a co-author in my first-ever scientific paper! The scientists at Unistellar just submitted this analysis on the rotation period of #asteroid (7335) 1989JA to the Minor Planet Bulletin.

This is why I LOVE #CitizenScience!

Another banger from #JWST! This time an Early Release Observation processed by the community, the Einstein ring SPT0418-47 observed with MIRI imaging.

Here's a fun animation transitioning from JWST to JWST+HST to HST, and back again.

Saturn

Saturn is the 6th planet from the Sun and the 2nd largest in the Solar System, after Jupiter. It is a gas giant with an average radius of about nine and a half times that of Earth. At least 83 moons are known to orbit Saturn. Titan, Saturn's largest moon and the second largest in the Solar System, is larger than the planet Mercury and is the only moon in the Solar System to have a substantial atmosphere.

M10

Magnitude 6.6 globular cluster located 14,300 light-years away in the constellation Ophiuchus. The cluster is currently located about 16,000 light-years from the Galactic Center. It completes an orbit around the Milky Way galaxy about every 140 million years, during which it crosses the plane of the galactic disk every 53 million years.

NGC 7789 Caroline's Rose

Magnitude 6.7 open cluster located 7,600 light-years away in the constellation Cassiopeia. It was discovered by Caroline Herschel in 1783. When seen visually, the loops of stars and dark lanes look like the swirling pattern of rose petals as seen from above.

After combining the high rez and lower rez channel data... certainly still a lot of that background read noise going on, but that was a good exercise in trying to get a JWST workflow going.

@NicoLasaigues thanks, yeah! It’s difficult to remember, but I think I had no idea what to prioritise and was using quite a slow shutter speed for 2

My Saturn images from the last few years.

From left to right:
1) 2015, 6" Maksutov, phone digiscope
2) 2016, Mak & Canon 550D
3) 2020, same as 2)
4) 2021, Mak & ZWO ASI 178MM
5) 2022, 8" Newtonian & 178MM

I believe that setup 5 has more potential too, haven't had good seeing yet this 🪐 season.

Saturn from last night.
Taken with Dobson 8" + Barlow 2x + Neptune-C II.
The black line you see in the rings is called the Cassini Division, which was discovered by Giovanni Cassini in 1675.
I think this is my best Saturn so far 😊.
