NGC/IC Project Restoration Effort

===== NGC 5248 48" (5/15/12): beautiful two-armed spiral, very large, elongated ~3:2 SW-NE. The brightest portion is ~3.8'x2.5' but the faint, outer spiral arms increase the diameter to at least 5'. The galaxy is sharply concentrated with an intense oval core. The brighter spiral arm is attached to the north of the core, wrapping counterclockwise around the east and southeast side and it is lit up by several fairly prominent knots. The arm dims fairly abruptly on the southeast side but continues unwrapping to the south, extending outside and just beyond a mag 13.5-14 star 1.7' SSW of center. A mag 15.3 star is 0.6' N of center, just outside where the arm emerges on the north side. At least four distinct HII knots are in or near this arm, along with brighter segments. The following designations are from the 1983 Hodge-Kennicutt "An Atlas of H II regions in 125 galaxies". A faint knot, [HK 83] 26/28 is between the mag 15.3 star and the core. The arm brightens along the east side of the core and include the faint knots [HK 83] 13/15, 28" NE of center, and [HK 83] 5/6 1.0' ESE of center. The most prominent knot along with this arm is [HK 83] 5/6, 1.2' SE of center. The western spiral arm stretches to the north and also contains several knots (HII complexes/star associations). The first knot is [HK 83] 63, 0.8' W of center. A large brighter knot or arc ~1.1' NW of center includes [HK 83] 74/77/81. A faint knot, [HK 83] 66/71, is near the tip of this arm 1.5' NNW of center. A similar knot, [HK 83] 53, is 25" SE, on line with the core. 18" (6/7/08): bright, large, elongated NW-SE, 3.5'x2.4', sharply concentrated with a very bright, round 25" core. At 200x, two spiral arms extend out from the central region. The brightest and longest arm is attached at the west side of the core and gradually sweeps to the north. A couple of very faint, very small knots are embedded in this arm including one due west of the core. On the east end of the core a matching arm is attached that curves a bit more as it swings towards the south in a counter-clockwise orientation. A faint star is just north of the central region and a brighter star is 1.7' S of center. 17.5" (5/30/92): bright, large, slightly elongated WNW-ESE, 4'x3', well-defined small very bright core, almost stellar nucleus. A mag 13 star lies 1.7' SSW of center and a mag 15 star is embedded at the north edge of the halo. Appears slightly mottled or dusty but spiral arms were not seen.
