Just stepping into this field. For the users to get the grasp of the size and scale of the objects populating our night (and day) skies, I take attention to keep the same scale (a field of view of about 41.2x27.5 arcminutes) and start by introducing the most familiar objects.
Astrograph of M3 (Messier 3), a large globular cluster in Canes Venatici. This cluster is among the largest and brightest and is made up of around 500,000 stars. It is estimated to be 8 billion years old and lies 33,900 light-years away from Earth. Seen through a 80mm refractor telescope. A total of 12min of exposure.
