[Song: "Meet Me Tonight In Dreamland" by Henry Burr, recorded in 1910]
16 квітня 2020 року, коли Київ затягнуло димом, за 140 км від столиці в місті Ічня, небо теж мало сірий колір. А сонце втратило свою яскравість і на нього можна було дивитися неозброєним оком.

On April 16, 2020, when the smoke in Kiev, 140 km from the capital city of Ichnya, the sky was gray. And the sun lost its brightness and you could look at it with the naked eye.

The milky way in the beginning of summer. The light come from a car near the road, in the opposite of the field. Canon EOS 760d + Samyang 16mm f2.
Probably my sharpest moon shot ever. Seeing conditions were quite good in Luxembourg on the 19th of february. Gear: C11 & 3x barlow lens. The luminance data comes from my ASI 1600mm pro equipped with an infrapass-filter while the colour was recorded with my ASI 178mc. Increased saturation to hightlight the mineral composition of the surface.
Horsehead and Flame nebulae shot in three sessions across two years (in 2021 - 2022). Preprocessed in APP and Pixinsight and post-processed in Lightroom.
250 minutes total exposure time.
Horsehead and Flame nebulae on visible and infrared spectrum. Stacking of 250 shots of 30'' with iOptron + darks and bias. Stacking with DSS. Canon 5Dmk4 Full Spectrum, Tamron 600 mm f/6.3, iso 10k. Taken on 03.01.2022 from Sounion, S. Attica, Greece.

The Cave Nebula, Sh2-155 or Caldwell 9, is a dim and very diffuse bright nebula within a larger nebula complex containing emission, reflection, and dark nebulosity. It is located in the constellation Cepheus and is approximately 2400 light years from Earth.

The Sadr Region (also known as IC 1318 or the Gamma Cygni Nebula) is the diffuse emission nebula surrounding Sadr (γ Cygni) at the center of Cygnus's cross. The Sadr Region is one of the surrounding nebulous regions; others include the Butterfly Nebula. It contains many dark nebulae in addition to the emission diffuse nebulae.

Olypmic NP was one of the highlights of my visit in the PNW this summer. I was looking forward to visit the iconic beaches and do some nightscapes there. After a 10 hour drive from Crater Lake NP, I arrived at Kalaloch Lodge in perfect weather, but too late to scout my planned nightscape spots.
After an excellent dinner, I had to make the tough decision between heading down the beach below the lodge and do some night photography from there or to just call it a night and sleep in my cozy cabin and postpone my astrophotography to the nights to come.
I am glad that resisted the temptation and went shooting. Not only did I capture the beautiful summer Milky Way and some airglow over the breaking surf, aglow with biolumincence, but it was also the only night where I was able to do nightscapes. The following days and nights, dense fog was blocking the view of the stars and beaches.

I am pretty excited with my first narrowband image. Narrowbanding allows me to do DSO imaging from my light polluted suburban Bortle 6 backyard and even if the moon is in the sky.
Filters with a tiny bandpass of only 4,5 nm around the wavelengths of singly ionized sulfur (Sll), ionized hydrogen (H-alpha) and doubly ionized oxigen (Olll) are used with a monochrome astro camera to capture 3 different images that can be combined into a color image.
There is a catch though: SII and H-alpha are in the red spectrum, while Olll is teal. This makes it hard to produce an image with colors like the human eye would see.
The most common solution is to not even try to. That's what NASA did with the famous "Pillars of Creation" image from the Hubble Space Telescope. They assigned Sll to the red, H-alpha to the green and Olll to the blue channel. This is called the Hubble palette, a false color image that shows the distribution of the different gases.
My image shows the normally red Rosette nebula in the Hubble palette.
Here some additional facts from Wikipedia: The Rosette Nebula is a large spherical HII region located near one end of a giant molecular cloud in the Monoceros region of the Milky Way Galaxy. The open cluster NGC 2244 is closely associated with the nebulosity, the stars of the cluster having been formed from the nebula's matter. The cluster and nebula lie at a distance of some 5,000 light-years and measure roughly 130 light years in diameter. The radiation from the young stars excites the atoms in the nebula, causing them to emit radiation themselves producing the emission nebula we see. The mass of the nebula is estimated to be around 10,000 solar masses.

First serious imaging session with my new ZWO ASI2600MC Pro camera. Really picked up a lot of stuff. As always, my processing leaves little to be desired but the quality of the raw images delivered from the new camera (barely any noise) makes for a great final result after working in PixInsight. There's also hardly any amp glow, so not sure if darks were really needed but I used them anyway. More to learn. Anyway, this'll do.
