A set of 8 Reference Line Maps, charts and DSS photos of M30 . This series of maps has been developed for use with the Reference Line Method. This method adapts well to both binoculars and telescopes.
Observersation Notes:
1. Remember, just because the map shows two reference lines doesn’t mean you need to use both lines. Use only the N-S reference line and this object will be easy.
2. Webb’s description (References) is quite accurate: “Moderately bright, beautifully contrasted with 8 mag. star beside it.”
