My previous post mentions noise artifacts that can be produced within the camera . These are relatively rare and initially had me thinking I was looking at some legitimate and very unusual objects until some dark frame tests revealed their true identity. It is quite a coincidence that my next session produced a satellite flash and a camera artifact close to each other on the same frame. This two satellite plus artifact sequence shares the frame with the distinctive quartet of stars in Delphinus.
