NGC 1501 is a gorgeous planetary nebula in Camelopardalis. This is a great example of how well this telescope can perform when the seeing is good. This brings my check-out of this telescope to an end. Lesson learned; when the seeing is poor I may be better off using one of my faster wide field scopes, but when the seeing is good this telescope can do an excellent job capturing fine details in small targets.
NGC 1501 is currently well placed high in the northeast after sunset and it high overhead by 9 o’clock. Glowing faintly at magnitude 11.9 it can be a bit of a challenge, but shows well in a modest size telescope, say 10” or larger.
