M23 is an open cluster located about 2000 ly away in the constellation of Sagitarius.

Yesterday was the 40th anniversary of the Challenger Disaster. Many of us saw it live, and it became a moment that stood out in the memories of all who saw it. This tragic explosion brought on important safety changes that almost certainly saved lives in the future. May they never be forgotten.

I just used an iPhone 12Pro Max at 2.2X zoom through the eyepiece of an 8” Newtonian telescope
