UGC 9749 Ursa Minor Dwarf

11.5.2022 at 02.00 - Fregenal de la Sierra, Espanja (I)
Tapio Lahtinen, Tampereen Ursa

I’ve photographed some of these Milky Way dwarf galaxies and now in the spring I saw a picture of this rather challenging galaxy online. The distance in this dwarf galaxy is about 225,000 light-years. The galaxy is mainly made up of old stars and there is hardly any new star formation there. That’s why it’s so challenging when gas is no longer visible.

Monitoring of the supernova continues and dimming has begun

Algieba (Gamma Leonis)

9.5.2022 at 23.40 - Vantaa, Pähkinärinne
Paula Wirtanen, Ursa (Helsinki)

Two stars are very rarely observed here in the Sky Watch, even though they look pretty nice. The moon was nicely close to Regulus and Algieba yesterday, so at the end of a great lunar observation, I still wanted to explore the often-forgotten great double star, Gamma Leon aka Algieba, the lion's neck star (Algieba means lion's crest). With a 10x eyepiece at 150x magnification, the star was already clearly visible in two, quite close pairs. At 250x magnification, it already clearly distinguished the difference in the size of the stars. In the most handsome double stars, like Albireo, th...

Rho Ophiuchi pilvikompleksi

9.5.2022 at 02.47 - 03.51 - Estreito da Calheta, Madeira, Portugali (IV)
Otto Vehviläinen, Ursa (Etelä-Suomi)

During the holiday trip in Madeira, you had the opportunity to photograph the objects near the center of the Milky Way from the dark sky. Here’s a shot from the area of Antares and Rho Ophiuch combined with photos from a few nights. During the first night, the clouds rolled over, but on the second night, it was already possible to shoot as long as patience was enough to stand alone in the museum parking lot.

Supernova 2022hrs

9.5.2022 at 00.01 - 01.12 - Fregenal de la Sierra, Espanja (II)
Tapio Lahtinen, Tampereen Ursa

I took a slightly longer exposure from the supernova with a Spanish remote tube to get the colors and the galaxy forest captured.
