NGC253 the Silver Coin galaxy & NGC288 Globular Cluster
Close pair in Cetus
Uploaded 9/5/26

Low in the Fall sky looking south we find this pair of objects, a distant galaxy called NGC233 or "Silver Coin" galaxy, and the much closer globular star cluster NGC288. Both objects are in the constellation of Sculptor, the Artist. For a galaxy, the Silver Coin is really quite close at 12 million light years compared to 30,000 lightyears for NGC288 located in our MilkyWay galaxy.

An often neglected imaging target located low in the south on fall evenings is NGC253 - the "Silver Coin" galaxy and NGC288 a globular in our Milky Way galaxy. I can just fit both in the field of the RASA here, NGC253 is the closest major starburst galaxy at magnitude 7.5 and NGC288 is 9.4 magnitude.
