Description

This is an image of M46. It clearly shows the planetary nebula NGC 2438. My mystery is this. Towards the bottom of the image I have placed a white box around a small red blob. I have look at other web photos of M46 and the red blob is there also. Does anyone know what it is? Stretch the photo and look closely!
