Last week I was out at the observatory upgrading our imaging system. We installed an ASI 6200mm and modified the filter wheel. We now have BVR and GRIZ filters so I took this shot of the Cocoon nebula with the Sloan filters for fun!

Just back from a 5 night speckle observation run at Mt. Wilson. We used the Hale 60" telescope for our data collection, but did get a chance to visit the 100" Hooker telescope. If you're interested in attending our next speckle run, please let me know. I will be leading the event. #astronomy 🔭

Hot off the press. Binary star pair AG 312. Position Angle 295.21 degrees, separation of 45.25 arc seconds tonight.
First measured in 1903 at 293/48.6"
Hmm... Are they dancing or is it common proper motion? I guess we wait a few hundred more years to find out...

Solstice is happening, shortest day of the year is upon us. As an astronomer I am sad that I will be losing the night, bit by bit as we move into summer.
I did take advantage of the dark last night and gathered data on HD5501, AH Leonis and AD Leonis.

A big part of running an observatory is filling time between partner requests with observations of interest for later analysis. So time to analyze rise and set times for mag 10+ flare stars.
