M72 Astrophotography with a RASA 8 and Color Camera

September 2023


We shot M72 and M73 at the same time for 10 hours total using our fast RASA 8 f/2 telescope under the Bortle 2 skies of Utah Desert Remote Observatories.


The M72 cluster and the M73 asterism are so close to each other that it just makes sense to get them both in one go. one time as they both are very close to one another. We did 300-second exposures and, after 10 hours, hoped to see some IFN in the area which we did once the data was stacked!
