Larger than the neighbouring three Auriga clusters but still fits in the 50 arcmin field of the 17mm OK. The stars are not packed as closely as in M37. On the N edge is an 8th mag. star at one end of an arc of a dozen stars curving S then W to end at another 8th mag star.

To the SW is an interesting, irregular cluster, NGC 2158. Examining this with the 8mm eyepiece at x260 it retains a misty appearance within the triangular fork of a Y-shaped asterism of about 10 stars. The inability to fully resolve the cluster suggests it is at a considerable distance. This cluster is one of the Herschel 400.
