NGC 6188 is an emission nebula located about 4,000 light years away in the constellation Ara. The bright open cluster NGC 6193, visible to the naked eye, is responsible for a region of reflection nebulosity within NGC 6188. NGC 6188 is a star forming nebula, and is sculpted by the massive, young stars that have recently formed there – some are only a few million years old. This spark of formation was probably caused when the last batch of stars went supernova.

IC 405 (Caldwell31) is a diffuse nebula visible in the constellation of Auriga, located at 1630 light years from Earth. In its direction you can see AE Aurigae, a variable and mysterious star, according to some studies it would be a star born in the region of the Orion Nebula about 2.7 million years ago and then moved to the Milky Way from there.

IC 405 shines with the radiation received from AE Aurigae, which ionizes its gases (mainly hydrogen) and gives it a red color; the blue patches are instead due to the reflection of the blue light of the star on the dark dust. IC 405 appears to be connected with other nebulosity systems, in particular with IC 410, visible one degree to the southeast; in reality they are much more distant objects.

IC 443 (also known as the Jellyfish Nebula and Sharpless 248 (Sh2-248)) is a Galactic supernova remnant (SNR) in the constellation Gemini. On the plan of the sky, it is located near the star Eta Geminorum. Its distance is roughly 5,000 light years from Earth.
IC 443 may be the remains of a supernova that occurred 3,000 - 30,000 years ago. The same supernova event likely created the neutron star CXOU J061705.3+222127, the collapsed remnant of the stellar core. IC 443 is one of the best-studied cases of supernova remnants interacting with surrounding molecular clouds.

Kronberger 63 is a planetary nebula in the constellation of Orion . It was discovered by Austrian Mattias Kronberger who is a member of the amateur group Deep Sky Hunters.

It is very faint and thus rarely imaged. Indeed my searches have found only one other image, produced by the Chart32 team in Chile.

This is a sequence of the lunar eclipse 2019.

Santiago de Chile.

Reading from left to right, you can see how the Earth's shadow cone covers the lunar surface, until it is completely submerged in a reddish copper color. This particular color of lunar eclipses is due to the shadow cast by the sun on the earth, generating a scattering effect of the light refracted by its atmosphere.

An airplane flies in front of the solar disk while the Sun begins to awaken its activity with AR 2757 in the center; a small sunspot, small in apparent size but as large as Earth.

To take this picture, the summer season is expected and the sunset and takeoff of the planes are calculated (every 10 minutes).

International Space Station captured on 20.1.2020 just after the sunset.
Elevation was roughly 50 degrees above the horizon so it was decent enough to get some sharp views, In this video, you can see the change of its orientation from SouthWest to North East, as it changes all the parts are clearly visible including solar panels and Modules
As usual, I tracked it with Edge HD 11" manually with my hand and stabilized the video in PIPP.

The California Nebula is an emission area located in constellation Perseus. It appears to resemble outlines of State of California on long exposure photographs, like this one. It has a very low surface brightness and it's very difficult to observe visually. Distance from my hometown Oulu, Finland, is about 1000 light years.
