Another successful overnight rooftop imaging run. The Moon is still very new, so I decided to image without the light pollution filter for a while.

Globular cluster Omega Centauri, Messier 24 (the Sagittarius Star cloud) and the Helix Nebula.

The overnight bounty off the :seestar_s30: from the city.

The fighting dragons of Ara, the Corona Australis molecular cloud, the Helix nebula and the Sculptor galaxy with globular cluster NGC 288.

These are stacks off the seestar, they’ve not been post-processed to get rid of the light pollution gradient.

Het wordt in de zomermaanden niet echt donker in Nederland ,rond 24 uur een poging gedaan wat redelijk goed gelukt is, de telescoop heeft in een klein uurtje 300 foto's gemaakt en er een stack van gemaakt tot 1 afbeelding van. dit 👇

I did another round of rooftop imaging, despite the haze and fog. Turned out fine!

The first image was without the light pollution filter. Given where I am and the conditions, I am impressed!

Antares through Rho Ophiuchi, The Swan or Omega nebula, the Helix nebula, and Melbourne.

🌃 🔭 Slightly more successful inner city rooftop astrophotography overnight. Fog interfered with the final image though.

The Eta Carina nebula, the Lagoon and Trifid nebulae, the Eagle nebula, the Helix nebula.

The first three are all about 2 hours of data, the last one only 25 minutes. They are stacked and processed on the device only.

Galaxy cluster ACO 2197 centered on NGC 6160, 260 million light years away in Hercules. Many of the 'stars' in this picture are background galaxies, too numerous to list.

One thing I checked out with the Seestar last night was the Rho Ophuici Cloud Complex. I only managed to get just over half an hour of images before the clouds appeared, and the Moon was certainly not helping either, but taking the look at the data now I can already see the potential.

Definitely need to revisit this next time I have clear skies, preferably without scattered Moonlight, ideally with less light pollution too (can't use the light pollution filter on this). It's going to need a lot more exposure time and, I think, a 4 pointing mosaic in order to get the whole cloud complex in frame.

Removing background gradients is really challenging here because there's so much stuff! There's gas and dust almost everywhere so there's barely any truly empty sky to measure the background in. That makes it especially important to minimise background gradients in the data to begin with, i.e. take images close to zenith and with no pesky Moon nearby.

Rather bright for a UGC:
Active Galaxy Nucleus Candidate UGC 11453, 200 million light years away.
The bright 'star' below the nucleus is apparently a companion galaxy PGC 63313.
Further down at 5:30 is edge-on PGC 91656, 170 mly.

Center: Active Galaxy Nucleus Candidate NGC6792, 210 million light years away in Lyra.

NGC 5678, 107 million light years away in Draco. There is a hint of a faint extended spiral arm on the right side.

Bonus astrophotography! I though I was done for the next little while as I was expecting there to be enough cloud tonight to ruin any plans I made, but as it turned out it was completely clear for the first half of the night. So I improvised and managed to get a good 4-ish hours on the Running Chicken Nebula and Pearl Cluster, then just played around in interactive mode looking at some different sorts of targets, getting ideas for the future.

That included my nemesis the Moon, which has been up and brightly illuminating the entire sky for most of every clear night that I've had since getting the Seestar 4 weeks ago. That is why up until now I've concentrated almost exclusively on emission nebulae that I can use the light pollution filter with.
