The Caroline referenced in the name of this object is Caroline Herschel, sister of William Herschel. The two Herschels were frequent collaborators in astronomical pursuits. Caroline discovered this cluster in 1783, and it is also known as the White Rose Cluster, or NGC7789.

I have to be honest - I don't see the basis for the name, but then I've never really undertaken much visual astronomy. Perhaps it is only this way that the resemblance to a swirl of rose petals can be detected.

More information about this object can be found on its Wikipedia page.

I chose to target this object because of the short window of clear sky available at the time, having read that capturing star clusters didn't require as much exposure time as fainter objects. I guess that's true, but it's also true that the more time spent on any object, the more the quality will improve (assuming the time is well spent capturing good quality data).
