How o you find the Names of the types of NGC/IC objects:

Classifications: G, GiP, GiG, PN, EmG, ISM, Sy2, rG, IG, etc.

ex. PN = Planetary Nebula

Also is there a database that contains the Common Names of these NGC/IC objects:

ex. Pinwheel Galaxy or Blue Snowball Planetary Nebula.

These give some galaxies but do not explain Otype and Mtype. Otype classifications are G, GiG,GiP,EmB,etc. Mtype classifications are Hubble's classes: Sa,Sab,SB,SAB,E,etc.
