M45 The Pleiades or Seven Sisters
A prominent feature of the winter sky, the appearance of the Pleiades changes notably depending on the way you view it. A small telescope or binoculars reveals why the close grouping of bright stars attracts our attention, and then a long camera exposure reveals the blue nebulous regions which almost seem to hold the group together. From dark sites they envelop the entire grouping but from here in the burbs they appear in patches.
Tech Stuff: Borg 55FL Astrograph; ZWO ASI1600MC Camera; Astronomik CLS filter; Ioptron CubePro8200 mount; 3 SharpCap Live stacks of 4 second exposures totaling 68 minutes intergrated and processed with PixInsight. Imaged from my yard 10 miles north of New York City.
