Can any one confirm my observation of stars around Sirius? I have the attached photo which shows few faint stars around the star Sirius. The image is flipped horizontally to match with my view in the eyepiece and is about 25'x25' FOV. Arrows A and B point to the location of two stars of about magnitude 9.5 and 10.5 respectively that I observed last week on a clear night from Van Nuys using my ETX-125 scope.( I confirmed my observation again tonite) But I noticed that those two stars don't show up in my Sky Safari Plus version 4.5.3 iPhone App.
According to the Sky Safari specs the Plus version includes all the stars up to mag 12 so these two stars ( A & B) should be included. The mag 9.5 and 10.5 is my best guess. I wanted to check what's faintest star I could see with my scope and the best I could do was about mag 11. If anybody who has sky safari pro version email me the screen shot of the same region to make sure those two stars exists!
