February observing highlights
Richard Navarrete
NGC 2169 – the 37 Cluster in Orion – in the area of the constellations upraised arm – Transits around 9:30 Herschel 400 list
Hidden Treasure # 36 – Steven James O’Meara called it the Little Pleiades, believed to first be first sighted by Hodierna
Medium Scope
NGC 2403 – Galaxy in Camelopardalis Mag 8.4 - Transits around 11:00 Herschel 400 list
My notes. –Wow! Large and bright. No good guide stars. 12.5” dob
Caldwell 7 - from Sky and Telescope “it was discovered by William Herschel in 1788. It is an outlying member of the M81 Group, and is approximately 8 million light-years distant. It bears a similarity to M33, being about 50000 light years in diameter and containing numerous star-forming H II regions.”
Large Scope
NGC 2467 Nebula in Puppis mag 7 – Transits around midnight Herschel II list
AKA – skull and crossbones nebula
My notes – Large, bright, irregular, round - 18”Obsession
Hidden Treasures #43
Herschel’s note – Large, pretty, bright, round and easily resolvable 6’ or 7’diameter, a faint red color is visible, a star of 8th magnitude is not far from the center but not connected.

12x36mm IS binocs (2/25/25): very small glow easily seen surrounding an 8th mag star.
Remarkable HII complex with visible structure similar to the red DSS2 image. The main region (NGC 2467) is an irregular oval or potato shape, elongated SW-NE (~6.5'x5'). The brightest section is a thick curving arc or filament along the S and SW border oriented ~E-W. The mag 8 star HD 64315 (O6V-type) is near the center.A prominent dust lane oriented WSW-ENE runs along the northern border and cuts off a fainter region of nebulosity extending north and west. The dust lane appears widest on the W end and tapers as it extends ENE along the border. A small bridge of nebulosity spans the two sections near the center. The outline of the northern half roughly forms a half-circle and combined with the main region forms a complete ellipse with major axis oriented NW-SE. Although the N section is fairly uniform in surface brightness, a slightly enhanced region is towards its N end (involving a 12th mag star).At the position of cluster Haffner 19 (~11' NNE of NGC 2467) is a fairly bright, perfectly round patch of nebulosity (2.5' diameter) - probably a shell or bubble around the cluster. At the position of cluster Haffner 18 (immediately NE of NGC 2467) is a 3' region of irregular, patchy nebulosity and a few stars.A large detached eastern section contains two main parts: A relatively bright, roundish patch, ~5' in diameter, is 15' ENE of NGC 2467. A 10th mag star is at its E end. Secondly, an elongated section of nebulosity, roughly 7' x 2' NNW-SSE is only a few arcmin NE of the fairly bright round glow at the position of Haffner 19.
