- Rules and Observing Info -

Technically, this isn’t really a rule… but let’s just say that: “Finding the objects on this observing list by star-hopping is enthusiastically encouraged!”
Observation Logging:
Record your observations with an observing form.
All that’s required is a simple log sheet with: Your name and location, the date of observation, a general idea of the weather conditions that night, the type of telescope used, the object name, the date and time you found it, and a description of what it looks like. Yes, that is a simple log sheet, because… no sketches necessary!
Which means you can stay up as late as you want hunting for clusters and not have to worry about drawing them, or dealing with time-consuming sketches “disappearing” from dew-soaked pages after a humid night (especially since many of these clusters are summer objects…)
Observing Forms:
Observing forms are available for download HERE.

Once you’ve completed the list, you can either turn in your observing forms, or scan them and send by e-mail to:
