NGC/IC Project Restoration Effort

===== NGC 4239 is the only one of Pechule's five nebulae listed in AN 2710 to have been listed in the NGC with a credit to him. In spite of his being a careful observer with access to micrometers (he regularly measured planets, asteroids, and comets at with the 11-inch Merz refractor at Copenhagen through the latter part of the 19th century), he gave only crude positions for the nebulae (0.1 min of time and 0.1 deg), estimated from the BD charts. That for N4239 is nevertheless within two arcmin of the modern position. Dreyer credited two of Pechule's nebulae only to Borelly (NGC 3933 and 3934); this is probably a good thing as Borelly's positions are much better. And the remaining two nebulae in Pechule's paper are not in NGC at all. They did not enter the catalogues again until they were picked up for CGCG and MCG: CGCG 098-033 = MCG +03-31-025 and CGCG 098-035 = MCG +03-31-027 = UGC 7032. Pechule has only a single position for these two along with a comment that they are possibly no more than stars. I suspect that this is why Dreyer skipped them.

===== NGC 4239 17.5" (5/23/98): fairly faint, fairly small, elongated 3:2 NW-SE, 0.9'x0.6', weak concentration. Easy to locate as situated between two mag 10.5 stars 2.9' WSW and 2.1' NE.
