Naked Eye Objects:

Name R.A. Decl. Details
  M44!
(NGC 2632)
08hr 40.1m +19° 59' The "Beehive" or "Praesepe" - appears as a hazy patch of light. An open cluster at mag. 3.1, 95 arc minutes across. Contains 200 stars of mag.6.3 to 14, easily resolved in 7 x 50 binoculars. First observed telescopically by Galileo.Use lowest power or finderscope. (Cnc)

Small Scope Objects:

Name R.A. Decl. Details
  M67
(NGC 2682)
08hr 50.4m +11° 49' A bright open cluster of 200 stars, mag. 6.7, only 30 arc minutes across. Located five times as distant as M44. One of the oldest clusters, at 3.2 billion years. Easy in binoculars or finderscope. (Cnc)
  NGC 2683! 08hr 52.7m +33° 25' The brightest deep-sky object in Lynx. An Sb spiral, hard to miss at mag. 9.7. Measures 9.3 x 2.5 arc minutes, with high surface brightness. Look for dark lanes with large scopes at high power. (110NGC) (Lyn)

Big Scope Objects:

Name R.A. Decl. Details
  NGC 2775 09hr 10m +07° 02' A 10th magnitude Sa spiral galaxy, 4.5 x 3.5 arc minutes. Located near the Cancer/Hydra border. (Cnc)
  NGC 2419 07hr 38m +38° 53' One of the most remote globular clusters known. Small and faint, only 4.1 arc minutes in size, glowing at magnitude 10.4 - 90 Kiloparsecs away.(Lyn)
  NGC 2541 08hr 15m +49° 04' A fairly bright spiral galaxy at magnitude 11.8 - 6.6 x 3.5 arc minutes in size. (Lyn)
  NGC 2500 08hr 02m +50° 44' A barred spiral, only 3 x 2.7 arc minutes in size. Mag.11.6.(Lyn)
  NGC 2537 08hr 13m +46° 00' The "Bear-Paw Galaxy" - fairly bright and compact. Mag. 11.7, 1.7 x 1.5 arc minutes. In large scopes appears circular with a brighter, incomplete ring around the outside. (Lyn)
  IC 2233 08hr 14m +45° 44' Located in the same low power field as NGC 2537, one of the thinnest galaxies known. 4.7 arc minutes long, but only 0.6 wide. Magnitude 13. (Lyn)
