NGC1624
About this celestial object
NGC 1624 as a small winter target — subtle and low surface brightness.
Compact, low-surface-brightness objects like NGC 1624 demand good contrast; details are easily lost against the background, visually and in images.
275 x 10 seconds sum to 45 minutes — enough to bring out the weak structures despite 53% humidity.
The 250 mm focal length and F/5 combination leaves room in the field and keeps stars fine.
