Collinder 187 is a 9th magnitude Open Cluster appearing in the constellation Puppis. It is 7133 light years from our solar system.

HD 71200 is a 8th magnitude Star appearing in the constellation Puppis. It is 775 light years from our solar system. It is a yellow-white subgiant of spectral type A8/9IV. Its surface temperature is 7652 Kelvins - 1.3 times hotter than the Sun's - and it is 2.7 times the Sun's diameter in size. This star's total energy output, or luminosity, is 22 times the Sun's, and it has a mass of 1.8 Solar masses.

HD 70963 is a 6th magnitude Double Star appearing in the constellation Puppis. It is 698 light years from our solar system. It is a white main-sequence star of spectral type A0V. Its surface temperature is 9790 Kelvins - 1.7 times hotter than the Sun's - and it is 3.6 times the Sun's diameter in size. This star's total energy output, or luminosity, is 107 times the Sun's, and it has a mass of 2.9 Solar masses.

The interesting thing about this image is the detail that the IMX294 has been able to capture with only 15 "in the stars marked with an arrow. If the view does not deceive me, blue nebulae spots appear around the stars that could be material ionized.
