NGC 6231 False Comet Region (200mm 5DII).jpg
The complex region of NGC 6231 in the tail of Scorpius, with the brightest star cluster at lower right being NGC 6231 itself while the cluster at centre is NGC 6242. The nebula is IC 4628. The pair of bright stars at top are Mu 1 and 2 Scorpii. The colourful double star at bottom is Zeta 1 and 2 Scorpii. To the naked eye this area appears elongated and fuzzy, like a comet. It was mistaken for Comet Halley in 1986.
This is a stack of 4 x 2-minute exposures with the 200mm lens at f/2.8 and filter-modified Canon 5D MkII at ISO 2500. Tracked on the AP 400 mount.
