Messier Marathon 2025
(probably won’t occur this Satruday night, but we’ll use these for whenever we manage to hold it).
We will award club certificates for participants in the Messier Marathon at CRO tonight.
We’ll have four categories:
Manual Telescope
Go-to Telescope
Binoculars
EAA
In each category we’ll have 3 levels of accomplishment:
50% (55 objects observed)
90% (99 objects observed)
100% (110 objects observed)
To receive a OKCAC certificate submit your observation sheet to: observingcoordinator@okcastroclub.com. Certificates will be handed out at the meeting following the submission.
The club rules are simple. Observations must be completed in one night. Record your observations on an observation sheet (doesn’t matter which one you choose). Submit your observation sheet to the email address above. You must indicate at the top of the sheet what category you completed. For EAA observations, you must record an image of the Messier object, in addition to completing the observation sheet. Those should be posted on an online site for everyone to view and enjoy!
Observation sheets are available at CRO, though I’d recommend finding one online that you like, downloading and printing it before you go out. There are numerous sheets online you can find and print.
