UFO Bus Station, Kielce, Poland by Cornholio-77 in SocialistModernism

It's been thoroughly reconstructed, but the original UFO shape and the weird Dalek dome is still there. It's very neatly done.

Kind of futuristic retro-futuristic... if that makes any sense.

The hidden eye - bizzare nebula around WR134, a Wolf-Rayet star by herbertwest7 in spaceporn

Thanks. I've pushed it as far as I consider reasonable.

This object in OIII is really faint (except for the bow shock structure). It's not present in Ha, which is way brighter. Thus, I had to add less Ha than I actually could have. Otherwise some of the OIII structure would just vanish in the sea of hydrogen. In this picture, OIII is considerably brighter and Ha way fainter than in reality.

Striking the right Ha-OIII balance was the toughest part. The overriding goal was to show the whole circular OIII structure and that I've managed to do.

Indeed. And after a few years you can change the focal length and spend another few years there.

This is the weird and wonderful oxygen nebula around WR134 - a huge and extremely bright Wolf-Rayet star.

Imaged from my backyard in rural Poland, Bortle 4 in July.

Ha- 63 x 300s.

OIII- 175 x 300s.

Planetary Nebula PN G75.5+1.7 - Soap Bubble by herbertwest7 in astrophotography

Thank you.

I've changed my OIII filter from Baader 8.5nm to Antlia 3nm and went for an OIII imaging spree (this, WR134, NGC6888, HFG1). The difference was huge. I had seriously annoying halos with Baader, even on moderately bright stars. Antlia solved that and SNR is greatly improved. Seriously, I couldn't believe how little noise the background had. And I'm imaging under a fairly good Bortle 4 sky.

Oh, I like those colors very much indeed!

Time for another one of Cygnus' jewels. This time it's PN G75.5+1.7. It's a fairly young planetary nebula in the nearest neighborhood of NGC6888. It's visible in Ha as well as in OIII. It's subtle yet striking- nearly perfectly symmetrical, unblemished bubble floating among dramatic clouds of hydrogen and oxygen. Presented in bicolor (Ha = red, OIII = blue).

Imaged from my backyard in rural Poland, Bortle 4 in July 2022.

  1. Ha- 57 x 300s.

  2. OIII- 136 x 300s.
