Oh dear! I just updates the Guide s/w with the latest version but
now, many of the Messier objects - such as M27, are surrounded by
stars covered in red circles. I have never had this before this new
version. The circles make it impossible to compare star fields. I
have checked the overlays etc but5 cannot find an option to turn them
off, whatever they are. Can anyone tell me what is going on here?

TIA
