For the last clear night  (at least for a few days according to Astrospheric), I decided to only target NGC 7789.  I did so because Saturday morning I want to head to spin class at 08:00, so I want to head to bed before 00:00,  I made bed by 00:35, I did make spin class, even though I was a bit tired.  Since clear nights have been so few and far between here in New Jersey, I have adjusted some of my exercise schedule to fit.  Most of the time I am really tired the next day and I just don't want to take a bike ride or head to the fitness center or even spend time in front of the computer processing, but I am drawn to imaging and just enjoying the night. 

NGC 7789 - Caroline's Rose
NGC 7789 is an open cluster that lies in Cassiopeia near the plane of our Milky Way galaxy. One of the major omissions from Charles Messier's catalogue, it was discovered by Caroline Herschel in 1783. Her brother William Herschel included it in his catalog as H VI.30. This cluster is also known as "The White Rose" cluster or "Caroline's Rose" because when seen visually, its loops of stars and dark lanes look like a swirling pattern of rose petals.This cluster is large, rich, fairly dense, and well-resolved. At least 150 stars are visible in a 16' area. The cluster's brighter members are 11th to 12th magnitude objects distributed in concentric rings. NGC 7789 has no distinct border: its outlying stars seem to blend imperceptibly into the surrounding star field, only the eastern edge being at all abrupt. A small detached patch of stars is 3' south of the cluster, and a tiny smudge 2' west. With a total apparent magnitude of 6.7, NGC 7789 compares favorably with many of the Messier star clusters.Uniformly spread over half a degree of sky, NGC 7789 is estimated to be 8,000 light-years distant. Its true diameter is therefore about 60 light-years. All the stars in the cluster were likely born at the same time, but the brighter and more massive ones have more rapidly exhausted the hydrogen fuel in their cores. The cluster's brightest members are G and K orange giants with absolute magnitudes around -2. Such stars are highly evolved: indeed, NGC 7789 is estimated to be 1.6 billion years old. This group is very old for an open cluster, but far younger than any globular cluster in our galaxy.
