Small Scope Objects:

Name R.A. Decl. Details
  d Corvi (Algorab) 12hr 30m -16° 31' This colourful pair of stars is separated by 24.2 arc seconds. The primary is magnitude 3.0, the secondary 8.4. Colors are often described as yellow and pale lilac.
  M68
(NGC 4590)
12hr 39.5m -26° 45' A bright globular cluster, mag. 8.0, 9 arc minutes in diameter. Difficult to resolve, use high power. (Hydra)
  M83
(NGC 5236)
13hr 37.0m -29° 52' A bright face-on Sc spiral measuring 8 x 10 arc minutes in size. At mag. 8.0, difficult to observe due to its position deep in the south. (Hydra)
  M48
(NGC 2548)
08hr 13.8m -05° 48' former "lost" Messier, large sparse cluster (Hydra) PLACEHOLDER

Big Scope Objects:

Name R.A. Decl. Details
  NGC 4361! 12hr 24.5m -18° 48' A bright blue planetary nebula, 80 arc seconds in diameter. Magnitude 10.5, central star mag. 13. (Corvus) (110NGC)
  NGC 4038! and
NGC 4039!
12hr 01.9m -18° 52' The "Antennae" or "Rattail" Galaxies - an 11th magnitude pair of interacting galaxies. Both galaxies measure only 2.5 x 2.5 arc minutes, mottled regions will be visible with larger apertures. (Corvus) (110NGC)
  NGC 4462 12hr 29m -23° 10' Located near b Corvus, this Sb spiral galaxy glows at magnitude 12.5. 3.7' x 1.6' in size, with a bright central core.
  NGC 3242!! 10hr 24.8m -18° 38' The "Ghost of Jupiter" - a bright bluish planetary in Hydra. Measuring only 40 arc seconds across, it glows at mag. 8.9. Look for the mag. 11 central star. (Hydra) (110NGC)
