The 36% Waxing Crescent Moon, May 2023

The 36% Waxing Crescent Moon, May 2023

May 25th, 2023, 9:10 p.m. local time

This week’s lunar trek continues with another evening of clear sky and an easier target. Why has the “target” gotten easier?

  • Higher in the sky each night, so less atmospheric disturbance
  • More lunar surface to focus on
  • Brighter disc each night, which helps with focusing, exposure, and telescope positioning

If you take note of the “Equipment Used” section I post at the bottom of each article, you may have observed that the only variable changing night-over night is the exposure. It keeps getting shorter and shorter since the Moon is brighter and brighter every night.

I will try to keep these evening astrophotography sessions moving along while they remain available and viable. Hopefully at least another few days!

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
  • 1/350 sec exposure
  • ISO 57
  • Focal length: 7mm
  • Touchups in PaintShop Pro and AfterShot Pro

Thank you for reading my article. Donec deinde tempum.
