At 380x, perhaps 75 stars are resolved, mostly in the outer halo and an edges of the small, bright, concentrated core. A brighter mag 12 star is just NE of the core, but most of the resolved stars are mag 13.5-15. The halo is fairly rich, but unevenly distributed with more stars resolved on the north side.

  PK 303+40.1 - 17.5" - With listed dimensions 938"x636", Abell 35 is a huge, low surface brightness ancient PN. On this night it was immediately seen at 100x using an OIII filter surrounding the mag 9.6 central star (a white-dwarf companion is actually the ionizing star). It appeared roughly 6'x4' extended SW-NE with the mag 9.6 offset NE of center. The brightest part of the nebulosity is near this star and in the vicinity just SW. The nebulosity doesn't quite reach a mag 10.5 star situated 5.5' SW of the central star but it seems to extend to a mag 11.5 star [2.7' following the central star]. Although the surface brightness is very low it is clearly irregular and leaves you wishing for larger aperture.

  24" (4/11/08 - Magellan Observatory, Australia): M83 had a photographic appearance in the 24" at 200x. The bright "bar" was elongated SW-NE and roughly 3'x1' in size with a well-defined bright, round core, 1' in diameter. The first prominent arm is attached at the NE end of the bar and sweeps south (counter-clockwise) on the east side of the core, wrapping around the southwest side and spreading out a bit as it terminates to the south of the core (~3' from the center). This arm has a high contrast along its outer edge and a couple of faint stars are superimposed near where it attached to the bar. On the southwest end of the bar a second prominent inner arm emerges and abruptly wraps counter-clockwise around the galaxy on the west side as it heads north. This arm continues to wrap around the north side before spreading out on the NE side and merging into the outer halo ~3.5' from center on the NE edge of the halo. A more ill-defined third arm also emerges from the core on the south but sweeps more gently to the west (instead of heading north) on the outside of the second arm. It spreads out and fades into the general glow about 3.5' SW of center near a mag 13-13.5 star. Offshoots of the main arms are difficult to trace and contribute to the general background glow of the halo.

    NGC 5128 - 24" (4/11/08 - Magellan Observatory, Australia): I didn't take detailed notes with the 24", but the appearance was mesmerizing at 200x. The equatorial dust lane was more contrasty and exhibited finer texture and scalloped detail at the edges than I've observed previously in smaller scopes from Australia.
