Description

NGC 752 (also known as Caldwell 28) is an open cluster in the constellation Andromeda. The cluster was discovered by Caroline Herschel in 1783 and cataloged by her brother William Herschel in 1786, although an object that may have been NGC 752 was described by Giovanni Batista Hodierna before 1654.

The large cluster lies 1,300 light-years away from the Earth and is easily seen through binoculars, although it may approach naked eye visibility under good observing conditions. A telescope reveals about 60 stars no brighter than 9th magnitude within NGC 752.

This is reprocess of image originally done December 2018 and was 3rd image ever with own camera and tracker. As white nights here but an unusual slow night at work I decide to redo plus found a few more usable lights. ISO 800 and f3.5. Was poor pointing on this but is kind of cool surprise see Triangulum so clearly.
