Small Scope Objects:

Name R.A. Decl. Details
  a UMi (Polaris) 02hr 32m +89° 16' The "North Star". Shines at mag 1.99 (slightly variable) is the 49th brightest star. Polaris has a pale blue companion at 9th mag, 18.5 arc seconds distant. (UMi)
  NGC 6543! 17hr 58.6m +66° 38' The "Cat's Eye Nebula" - an easy mag 8.8 planetary nebula, only 18 arc seconds in diameter with a mag. 11 central star. (110NGC) (Dra)
  M102
(NGC 5866)?
15hr 06.5m +55° 46' A bright but almost featureless E6p lenticular galaxy, mag 10.0. - 5.2 x 2.3 arc minutes. Appears originally to be a duplicate observation of M101. (Dra)

Big Scope Objects:

Name R.A. Decl. Details
  NGC 5907!! 15hr 15.9m +56° 20' A classic edge-on Sb spiral galaxy. Mag 10.4, 12.3 x 1.8 arc minutes in size, close to M102. Dust lane visible in larger scopes. (110NGC) (Dra)
  NGC 6503! 17hr 49.4m +70° 09' A fairly bright Sb spiral galaxy at mag 10.2. 6.2 x 2.3 arc minutes. (110NGC) (Dra)
  NGC 5985 Group 15hr 40m +59° 20' The "Sampler" - brightest of a nice trio of galaxies, a nice multi-arm face-on Sb spiral at mag 11.0, 5.5 x 3.2 arc min. Look for 12th mag NGC 5982 (elliptical) and mag 13.9 NGC 5981 (edge-on Sb-c) in the same field. (Dra)
  NGC 4236 12hr 17m +69° 28' A bright barred spiral galaxy. 18.6 x 6.9 arc min, mag 9.7. (Dra)
  NGC 4256 12hr 18m +65° 54' An edge-on Sb spiral located 3.6° south of NGC 4236. Mag 12.4, 4.6 x 0.7 arc minutes. (Dra)
  NGC 3147 10hr 17m +73° 24' A nice, compact Sb galaxy mag 11.3, 3.9 x 3.4 arc min. (Dra)
  NGC 6643 18hr 20m +74° 34' A multi-arm Sc spiral, mag 12.0, 3.0 x 1.3 arc min. (Dra)
  NGC 6015 15hr 51m +62° 19' An Sc spiral, mag 11.2, 5.4 x 2.3 arc minutes. (Dra)
  NGC 6217 16hr 33m +78° 12' Another Sc spiral, mag. 12.0, 3.0 x 2.4 arc min. (UMi)

Challenge Objects:

Name R.A. Decl. Details
  Markarian 205 12hr 22m +75° 19' A "bright" Quasar, at mag 14.5. Connected (?) to galaxy NGC 4319, 40 arc seconds south of the core of the galaxy. (Dra)
  NGC 3172 11hr 50m +89° 07' "Polarissima Borealis" - a rather unremarkable galaxy, except for the fact that it is the closest NGC to the north celestial pole. Mag 13.6, 0.7 x 0.7 arc minutes. (UMi)
