Big Scope Objects:

Name R.A. Decl. Details
  NGC 957 02hr 33m +57° 31' Located less than 2° away from The Double Cluster, but smaller and fainter. 40 stars, mag 11 to 15, 10 arc minutes in size. Total magnitude 7.2.
  NGC 1245 03hr 15m +47° 14' Another nice open cluster of 40 stars, mag 11 and fainter. 20 arc minutes in diameter. Total magnitude 6.9.
  NGC 1491! 04hr 03.4m +51° 19' A compact but bright emission nebula, 3x3 arc minutes. (110NGC)
  M76
(NGC 650/51)
01hr 42.4m +51° 34' The "Little Dumbbell Nebula" - an 11th magnitude planetary nebula, a smaller version of The "Dumbbell Nebula" in Vulpecula. One of the toughest Messier objects (?) 140 x 70 arc seconds in size with a mag 16.5 central star.
  NGC 1023! 02hr 40.4m +39° 04' An E7 elliptical galaxy, 4.5 x 1.3 arc minutes. Magnitude 11.0 with high surface brightness. (110NGC)
  NGC 1275 03hr 20m +41° 31' "Perseus A" - a 13th mag peculiar galaxy. Difficult to observe with smaller scopes, 0.7 x 0.6 arc minutes in size, 8" scope probably minimum aperature.

Challenge Objects:

Name R.A. Decl. Details
  NGC 1499 04hr 04m +36° 25' The "California Nebula" - a large, faint emission nebula, 145 x 40 arc minutes in size. Best observed from dark skies at very low power (8 to 16X) Somewhat less invisible with an H-beta, OIII or UHC filter.
