While we’ve been at home for the Great Distancing, I have been experimenting with what I can see from my suburban driveway.
I know that I can’t see the Milky Way from my driveway. A long time ago, when I went to a star party in a rural area, I learned that Messier objects that are easily seen with my telescope with dark skies couldn’t be seen from my driveway. But I can see the bright planets and the major constellations from my driveway.
I’ve been trying to figure out the limit on what I can see by going out with a sky map on my phone (I’m using GoSkyWatch), and looking at constellations and trying to find the dimmest star I can see. With a quarter-full moon not in my field of view, I can see stars as dim as magnitude 3.5. With no moon, I can see stars as dim as magnitude 4.
My next steps are to figure out the dimmest object I can see with the finder scope on my telescope, with the telescope itself, and with my camera.
What’s the dimmest star you can see in your skies?
