UGC 9749 Ursa Minor Dwarf - 11.5.2022 at 02.00 Fregenal de la Sierra, Espanja Observation number 106835

Visibility I / V

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.

Hyvä kuva vaikeasta kohteesta. Fokuksen täytyy ainakin olla kohdallaan. Mikä mahtaa olla näkyvien tähtien magnitudi galaksissa?

Kiitos.
ASTAP sanoo rajasuuruusluokaksi 20.4.
Näyttää galaksi tähdet olevan sellaista 18-19 magnitudin luokkaa.
