NGC/IC Objects

NGC 1807 & NGC 1817: Open Star Clusters (Taurus) RA: 05h 11.6m / DEC: +16° 36'.5
Instrument: 10-inch Starfinder

These closely grouped open clusters are positioned along the southern border of Taurus just across from Orion. My sketch renders the view in my 10-inch Starfinder equatorial Newtonian at 36X. The clusters share the northern half of the field. NGC 1807 occupies the northwest section and NGC 1817 the northeast. Lynga lists NGC 1817 as a 7.7 magnitude open cluster with 60 members. Fifteen are recorded in my sketch as a close knit congregation. Lynga's stats on NGC 1807 describe a 7.0 magnitude cluster with 20 members. Twelve are shown in the sketch, including several 8th and 9th magnitude sparkers. You'll find NGC 1807 and NGC 1817 about 33' north of 5.2 magnitude HD 33554, visible 10' inside the southern field boundary.
