The 90% Waning Gibbous Moon, October 2023

The 90% Waning Gibbous Moon, October 2023

October 2nd, 2023, 1:04 a.m. local time

For my several astronomy readers out there, it has been a while since I posted a good astrophotography image and article. I hope this one makes up a bit for the absence.

My hope is to capture more waning images of the Moon, as I have an ample supply of waxing images. Here is one example, a few days after the last Full Moon. The only issue for me is that I do not have a clear few of the East from my backyard, so I have to wait past midnight to get a picture like this. Of course there is a flip side, getting up before dawn, and I may have to employ this time shift to reach my goal.

Equipment Used:

  • 127mm Mak-Cass telescope
  • 23mm eyepiece
  • No eyepiece filter
  • iPhone 14 Pro
  • Smartphone telescope eyepiece adapter
  • NightCap app on iPhone
  • f/1.8
  • 1/2500 sec exposure
  • ISO 57
  • Focal length: 7mm
  • Touchups in PaintShop Pro and AfterShot Pro

Thank you for taking the time to read my article.
