C63 Helix Nebula
Photo description / processing
3 shots of 10 minutes each with a narrow band and no calibration. You can see how particles hit the sensor, leaving these worm-like trails. There are also just dead pixels and dithering traces. I decided not to retouch them in Photoshop and leave them as an example of cosmic radiation at work. Instrument: CHI-3-CCD.
