|NGC 1817: Open Star Cluster (Taurus) RA: 05h 12.5m / DEC: +16° 41'.0|
Instrument: 10-inch Starfinder
My sketch renders a 36X view in my 10-inch Starfinder equatorial Newtonian. NGC 1807 and NGC 1817 share the northern half of the field, with NGC 1817 offset northeast of center. 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, visible in the northwest quadrant, 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 1817 about 33' north of 5.2 magnitude HD 33554, which is the bright star blazing away just 10' inside the southern field boundary.
