This image replaces my first red-filtered 64 minute Track & Accumulate image from 02/15/2006. From the NGC / IC Project: Contemporary Visual Observation(s) for NGC 1662 NGC 1662 = Cr 55 = OCL-470 = Lund 141 04 48 29 +10 55.8 V = 6.4; Size 20 17.5": striking group of ~40 stars within 15' including a number of mag 9 stars. Many of the brighter stars are arranged in a "boat" shape with the bottom of the boat consisting of a string oriented NW-SE. In the middle is a mast, perpendicular to the longer stream of stars. The "mast" primarily consists of a bright quadruple (one with a fainter companion) of mag 8-10 stars (h684) with sides less than 1'. This group may be a scattered group of bright stars. - by Steve Gottlieb |
