The Palomar Globular Clusters are a unique and challenging list of 15 very faint globular clusters. Most of these were only found after scrutinizing plates from the Palomar Observatory Sky Survey (POSS). I stumbled upon one of these clusters while looking around in Starry Night Pro and building a list of targets for my next observing session. It took several imaging sessions to capture my first Palomar Globular.The web site http://www.deepsky-visuell.de/Projekte/PalomarGC_E.htm - offers a photographic view and sketch of each of the Palomar globulars as well as a table reference.Palling Around With Palomar Globular Clusters, by Bob King, August 17, 2016 at Sky and Telescope Magazine (https://www.skyandtelescope.com/observing/palling-around-with-the-palomar-globular-clusters/) offers a nice article on the Palomar clusters, photographs and finder charts.Astronomy-Mall also contains helpful observation information and a table of the Palomar Clusters at (http://www.astronomy-mall.com/Adventures.In.Deep.Space/palglob.htm).

Tom,
I am engaged in a project to image and observe all of the Milky Way Globular Clusters. So far I have completed nine of the Palomars and will process two more in a few days. The Palomars are challenging to image and are interesting because they don't immediately look like a globular cluster. As part of my project I have learned how these objects, that look more like an open cluster, are classified as a globular cluster. HR diagrams are the key.

Great idea to create a dedicated Palomar GC Group, Tom!
