30分に1本の電車を待ってベンチに座っていた。のんびりとこういう時間もいいものだ^^
She was sitting on a bench waiting for the train that comes once every 30 minutes. It's nice to have a relaxing time like this.

Terminal Railroad of St. Louis's 101 crew has pulled across the diamonds at WR Tower to deliver a string of empty tank cars for the Port Harbor RR for storage. The train will have to be cut in half due to the length of the lead the TRRA uses to reach the PHRR.

WR 134 è una stella di Wolf-Rayet variabile, appartenente alla costellazione del Cigno, distante circa 5 700 al dal Sole, 400.000 volte piu luminosa del sole e terribilmente calda!!
WR 134 perde massa a ritmi esorbitanti, tramite venti stellari molto veloci che danno origine alla debole nebulosa di colore azzurro

***********************************************
WR 134 is a Wolf–Rayet variable star located about 6,000 light-years from Earth in the constellation Cygnus , surrounded by a faint bubble nebula driven by the star's intense radiation and fast wind. It is five times the radius of the Sun, but due to a temperature exceeding 63,000 K it is 400,000 times more luminous than the Sun .
WR 134 was one of three stars in Cygnus observed in 1867 that had unusual spectra consisting of intense emission lines rather than the more normal absorption and continuum lines. These were the first members of the class of stars that came to be called Wolf–Rayet stars (WR stars) after their unusual appearance was discovered by Charles Wolf and Georges Rayet. It is a member of the nitrogen sequence of WR stars, while the other two (WR 135 and WR 137) are members of the carbon sequence that also have OB companions. WR 134 has a spectrum with N III and N IV emission between two and five times stronger than NV, leading to the assignment of a WN6 spectral type. The spectrum also shows strong He II emission and weaker He I and C IV lines.
WR 134 is classified as an Algol-type eclipsing variable and has been given the designation V1769 Cygni, but the variation is not strictly periodic and brightness changes occur on timescales of hours to days.
Both hard and soft X-rays have been detected from WR 134, but their origin has not been fully explained. The emissions do not correspond to any star of the expected temperature, they are not sufficient to generate winds that would cause two hot stars to collide, and any compact source, such as a neutron star or a cold dwarf, would be in an unlikely orbit.
I've always thought Wolf-Rayet stars are so cool: ever since Hubble captured the iconic image of WR 124 (seriously look it up if you haven't seen it, it's I've always Wolf-Rayet stars are so cool: ever since Hubble captured the iconic image of WR 124 (seriously look it up if you haven't seen it, it's unreal), I've had this fascination with them. WR 134 is one such star located around 6,000 light years away in the constellation of Cygnus: it's the bright one at the center of the frame. While it is only five times the radius of the sun, but it burns incredibly hot, at over 63,000 K (that's 113,000 degrees Fahrenheit), and is **400,000** times as luminous as the Sun.
This image comprises over 300 five minute exposures from my backyard, or about 28 hours of data, focused on ionized hydrogen and oxygen. What makes the nebula you see here is the incredibly strong solar wind and radiation Wolf-Rayet stars are known for colliding with the surrounding interstellar medium. To give you an idea of the kind of power we are talking about here, this frame is over 50 light years across, and I was fortunate enough to be able to see it from my backyard. Still blows my mind when I think of it.
I continued to work on new Pixinsight techniques in this image. I used Muredenoise for the first time on the linear Oiii master, since it still had a little bit of noise despite the lengthy integration time. I was very pleased with the results: I’ll be building it into the linear workflow from here on out. I also tried Adam Block's star de-emphasis technique where you create a mask with halos around all the stars, cores protected, and replace the halo pixels with median sky pixels from the local area. I love it: I think it gives results superior to simply erosion via MT alone. I had intended to capture some RGB data for the star colors, but I think it turned out ok without it. Plus, I'm eager to move on to the next target. Imaging nights have been few and far between with all the rain we have been having, plus the smoke from the wildfires out west, and I want to make the most of it. Clear skies everyone. Stay safe.

CurvesTransformation to adjust colors, keeping a star mask in place to protect stars from oversaturation
Imported to Photoshop and Lightroom, then adjusted colors to suit. Also selective, light application of Camera Raw filter with negative adjustments to texture and clarity as a smoothing application.
Oddly enough, I never really did any major denoising aside from MureDenoise at the beginning. I usually use TGVDenoise.
