Discussion Overview
The discussion revolves around the classification and naming of NGC (New General Catalogue) and IC (Index Catalogue) objects, including various types and their common names. Participants seek to clarify the classification system and identify resources for further information.
Discussion Character
- Exploratory, Technical explanation, Meta-discussion
Main Points Raised
- One participant inquires about the classification types of NGC/IC objects, providing examples such as G, GiP, GiG, PN, and others.
- Another participant shares links to databases that may contain information on NGC/IC objects, including their common names.
- A participant notes that while some resources provide names of galaxies, they do not clarify Otype and Mtype classifications, mentioning specific types like G, GiG, and Hubble's classes.
- One participant mentions their long-term ownership of a printed version of the NGC catalog, indicating a personal connection to the topic.
Areas of Agreement / Disagreement
Participants do not reach a consensus on the classification types, and there are multiple competing views regarding the adequacy of the provided resources for understanding Otype and Mtype classifications.
Contextual Notes
Some classifications and terms remain undefined, and the discussion does not resolve the specifics of Otype and Mtype classifications or their implications.
