Overheard a guy at the observatory say he never checks his camera sensor for dust anymore
He was showing off a shot of the Orion Nebula at a local star party. Said cleaning was a waste of time, he just fixes it in post. I looked at his image later on a big screen. Every single star had a tiny dark spot from the dust, hundreds of them. It took me two hours to clone stamp them all out of my own photo from that night. That 'fix it later' attitude can ruin a good capture. Has anyone found a reliable, safe way to clean an APS-C sensor at home without sending it out?

Ugh, that's a perfect example of lazy editing making MORE work. I use a basic sensor loupe and a static brush, it's quick and stops those spots from ever happening.

Read a piece by a pro astro photographer who said a rocket blower is your first line of defense. They stressed to NEVER use canned air, the propellant can spray and ruin the sensor. For stubborn spots, they recommended those pre-moistened swabs made for your exact sensor size.
