I can't find SH2-308 in the Seestar application I see in the community many people who were able to observe it.
Could someone help me please
Go into Skyatlas-> Objects -> My Favorites->More-> Customize and enter the JNow coordinates wich are : Right Ascension 06h 54m 13s Declination -23° 55′ 42″
You can also see it in Sky Atlas as EZ Canis Majoris, although not search for it. Start from Sirius, move to M 41, then continue about the same distance until you find Omicron1 Canis Majoris. EZ Canis Majoris is right next to it.
