Barred spiral galaxy NGC 2903, about 30 million light years away. Just to its left is low surface brightness galaxy UGC 5086, 24 million light years away. One of the 'stars' below 2903 is a background galaxy 490 million light years away.

With a limited shooting window after sunset I tried to go for the Jellyfish nebula, NGC2903 and Mars. Captured with the @seestar.official S50

First light for the VariSky Observatory !
A lot of things missing (focuser, coma-coreector...), not the definitive camera... But least... It works !
A little time to test pointing and tracking, the acquisition process with Ekos/KStars. Doing it with an exoplanet transit and NGC2903.

Testing the limits of my smart #telescope by capturing barred #spiralgalaxy #NGC2903 (right side of photo). This #galaxy is found in the #constellation Leo. The bright star on the left is HD82394. I am in a bortle 5 sky here. #astrophotography #seestar Happy Monday!

Buenos días blueskitxs. Hoy, además de recordaros que la 🌕 le dará un mordisco al ☀️ hacia las 11 am, os traigo la luz de la galaxia #NGC2903 ,que llegó a mi #SeestarS50 🔭 después de un viaje de más de 20 millones de años 🤯 #astronomia #astronomy #astrofotografia #astrophotography #darkskies

Some days I like to find less known objects in the sky to further test the kickbuttosity of the Seestar S50.
Here is galaxy NGC2903. Mag 9.0.
62 mins of 30sec frames. Denoise and stack in S50. EQ mode. Lightroom mobile tweak.
I love this Galaxy.

First light on blue sky! Vestland had clear skies for once. NGC 2903 centered, NGC 2916 upper left. 2916 is 187 M ly away according to Stellarium, 2903 is 38 M ly. The smaller galaxies in the field are around 100 M ly. So 2916 is pretty big I think.
