Rosetta Target
This image of comet 67P/Churymov-Gerasimenko was taken on March 21, 2014, by the narrow-angle camera of the Rosetta spacecraft Optical, Spectroscopic and Infrared Remote Imaging System OSIRIS.

The telescopes got data on all their assigned targets overnight. Most will need a bit more processing than the seestar app can provide, though.
The original :seestar_s30: had a 3d printed spider on the lens, to provide diffraction spikes on bright stars. Hubble mode, as I like to call it.
That seems to not have affected its first target, spiral galaxy NGC300, but there is hardly any data for the other two relatively bright stars clusters. Lots of discarded frames.
There is supposed to be about 90 minutes of data on each, not 10 to 20. I assume it’s the spider, not that the targets were too low or behind the wattle tree.
At least they’re recognisable. The Pleiades, M45 and Collinder 69 (nice!) which is essentially Orions head. The brightest star in that is Meissa.
Farewell Rosetta: ESA Mission to End on Comet Surface
This view shows Comet 67P/Churyumov-Gerasimenko as seen by the OSIRIS wide-angle camera on ESA's Rosetta spacecraft on September 29, 2016, when Rosetta was at an altitude of 14 miles (23 kilometers). The European Space Agency's (ESA) Rosetta mission will co...

Farewell Shot of Rosetta by Philae Lander
The Philae lander of the European Space Agency Rosetta mission took this parting shot of its mother ship, Rosetta, shortly after separation on Nov. 12, 2014. The image was taken with the lander CIVA-P imaging system.

#Planet #Venus bewegt sich in den Tagen vom 8.11. - 18.11. in der Nähe des mag 1 hellen Stern Spica im Sternbild Jungfrau. Der kürzeste Abstand wird erreicht am 09.11. um 11:20 MEZ. Der Abstand beträgt dann 1°09'55". Die Elongation von Venus beträgt 24°. Venus geht 2 Stunden vor der Sonne auf und ein Feldstecher hilft bei der Sichtung von Spica. #Astrodon #Astronomie #Planeten

The Youngest Crater on Charon?
NASA's New Horizons scientists have discovered a striking contrast between one of the fresh craters on Pluto's largest moon Charon and a neighboring crater dotting the moon's Pluto-facing hemisphere. The crater, informally named Organa, caught scientists' atte...

Neptune False Color Image of Haze
This false color photograph of Neptune was made from NASA's Voyager 2 images taken through three filters: blue, green, and a filter that passes light at a wavelength that is absorbed by methane gas. Thus, regions that appear white or bright red are those that reflect sunlight before it passes through a large quantity of methane. The im...

Rosetta Comet In Action Animation
A short-lived outburst from comet 67P/Churyumov-Gerasimenko was captured by Rosetta's OSIRIS narrow-angle camera on July 29, 2015. The image at left was taken at 13:06 Greenwich Mean Time (GMT) (6:06 a.m. PDT), and does not show any visible signs of the jet. It is very strong in the middle image captured at 13:24 GMT (6:24 a.m. PD...

Rotation and Shape of Rosetta Mission Target Comet
This frame from an animated sequence combined 36 interpolated images of comet 67P/Churyumov-Gerasimenko, each separated by 20 minutes. This comet is the destination for the European Space Agency Rosetta mission in 2014.

Now that's a stellar crossover 🤩
We invited Dr. Becky Smethurst to our Headquarters in Germany, where we chatted about cosmic mysteries that could be solved with upcoming facilities, like our Extremely Large Telescope in #Chile.
➡️ https://www.youtube.com/watch?v=NI8gwNwHwf0
We also gave her a sneak-peek of some of the ELT components we're building and testing here. Stay tuned for more videos, both in her channel and ours, there's more to come!
Finally, some clear nights and targets visible from my balcony. Hello, IC 434, aka the Horsehead Nebula.
I took the opportunity to run some tests with my Askar 111F and a narrowband filter. Turns out that even at f/6.9, halos are still an issue with my SVbony filters. 5h of total integration time.
Really considering switching to a mono camera with proper filters rather than just replacing my dual-narrowband filters.
Atmospheric Waves
With its Multispectral Visible Imaging Camera MVIC, half of the Ralph instrument, New Horizons captured several pictures of mesoscale gravity waves in Jupiter equatorial atmosphere.

Everything You Wanted To Know About The 10 Mpc Volume

The sky was clear for a couple of nights this week, so we had the Dwarf 3s out. I was rather taken with this large and rather attractive open cluster. It's sometimes called the Southern Pleiades, or Theta Carinae Cluster, Caldwell 102 or IC 2602.
If you know the False Cross asterism (Diamond Cross to non sailors), that big star Theta Carinae is in it.

LORRI Looks Back
NASA New Horizons had an exciting flyby encounter with Jupiter in early 2007, and the spacecraft has been rapidly moving away from the giant planet ever since.

OK, I ended up with a little under 3 hours of good data on NGC 1433 last night, so here it is prettied up a bit with the Type Ia supernova SN 2026ahvu clearly visible.

Data from my Seestar S30 Pro taken from my Sydney backyard (Bortle 7), processed in Siril with Seti Astro and VeraLux scripts. Thanks to @CosmicRami for the tip.

Ariel at Voyager Closest Approach
This picture is part of NASA Voyager 2 imaging sequence of Ariel, a moon of Uranus taken on January 24, 1986. The complexity of Ariel surface indicates that a variety of geologic processes have occurred. http://photojournal.jpl.nasa.gov/catalog/PIA00037

Here's the supernova! ⭐💥
Captured #SN2026ahvu between the clouds from my backyard tonight. Only 30 mins of data here but its clearly visible with the Seestar S50, so am expecting a much nicer result from the bigger rig.
Idiot clouds got in the way again, sadly!
This light is about 46 million years old as the galaxy NGC 1433 is at this distance ....
Kinda neat I can do this from my backyard just 1.5 km from Sydney's city district (with all its lights)
