Objects To View With Different Telescopes
There are many kinds of deep sky objects to see: stars, double stars, open star clusters, globular clusters, galaxies, nebulae, and planetary nebulae.
Different size aperture and types of telescopes can give you different views of objects.

The larger the aperture and the darker the skies the better most deep sky objects will look. PAS has come up with some of our favorite deep sky telescopic objects that look good depending on the size of the scope and the darkness of the night sky.


(Darkness of the sky is shown in Bortle numbers. Bortle 1-3 is darkest, many miles away from any lights, like the antennas location Bortle 2. Bortle 4-5 is suburban or outskirts of the valley like Cave Creek or Carefree. Bortle 6-9 is inside the Phoenix city limits with various degrees of light pollution.)
5 inch refractor telescope:
Fall: NGC 7009 Saturn Planetary Nebula outskirts of Valley (Bortle 4-5)

Winter: NGC 7662 Blue Snowball Planetary Nebula , NGC 2169 “XY” star cluster outskirts of valley (Bortle 4-5)

Spring: Stargate asterism 2 nested triangles outskirts of valley (Bortle 4-5) NGC 3242 Ghost of Jupiter Planetary Nebula dark skies like the antennas area (Bortle 2)

Summer: deep red carbon star 1 Lyrae in Phoenix (Bortle 6-8), Collinder 399 Coat Hanger asterism outskirts of valley (Bortle 4-5)

Summer: M13 globular cluster outskirts of Valley (Bortle 4-5)



9 ¼ inch Schmidt Cassegrain telescope:
Fall: Albireo and Gamma Andromeda double stars blue and gold in Phx (Bortle 6-8)

Winter: Orion Nebula and Running Man Nebulae M42 &M43 in Phx (Bortle 6-8)

M35 Open Cluster Phx (Bortle 6-8)

Summer: Swan Nebula M17 (use OIII filter) and Lagoon Nebula M8, if south of the valley (Bortle 4-5)
14 inch Dobsonian reflector telescope:
Fall: Perseus double cluster Phx (Bortle 6-8), M37 open cluster outskirts of valley

(Bortle 4-5) , M17 & M20 Nebulae and Open Clusters NGC 7789 and M11 Wild Duck in dark sky area like antennas (Bortle 2)

Winter: Orion Nebula M42 in Phx (Bortle 6-8), Andromeda Galaxy M31 outskirts of Valley (Bortle 4-5), Open Clusters M41 and M50 dark area (Bortle 2)

Spring: M81 and M82 galaxies outskirts of valley (Bortle 4-5) M51 Whirlpool galaxy and M5 &M13 globular clusters, and Virgo region galaxies (M86 and surrounding area) all in dark area (Bortle 2)

Summer: M57 Ring Nebula outskirts of Valley (Bortle 4-5) , NGC 6826 Blinking Planetary Nebula, Helix Nebula NGC 7293, Veil Nebula Caldwell 33/34, Sculptor Galaxy NGC 253, M27 dumbell nebula dark area (Bortle 2)
22 inch Dobsonian reflector telescope:
Fall:

Just a note, the Moon and planets can be seen in all of the above telescopes even in Phoenix (Bortle 6-8)



You will see more detail on the planets as the aperture of the telescope increases.
