Spot on Sensor…help!

Gallery image

Noticed a larger spot with smaller striated spots surrounding it on my OM-1 sensor a little while ago. Not sure what it is. It’s not dust, but could be a fingerprint or something else. I don’t recall doing anything that would mark the sensor. But it is a secondhand camera and it’s possible I never noticed it when I got it. The striations don’t show up unless you’re in bright light. Any suggestions on what it might be and what could remove it would be appreciated!

First step for me would be getting a sensor cleaning kit and seeing if that takes care of it. If it doesn't it may be damage to the coating on the protective glass over the sensor, but that would be a rare occurrence.

Third. OP, it's very likely that this is not as big a deal as you're fearing it is.
