Hi all
Due to work and work related issues I haven't touched my astro gear in over three years. But now I have the time again and intend to get right back into it.
Fired up the camera yesterday to get some new darks for the library and noticed there is two rather noticeable column defects. I cannot recall them being there a few years ago.
Are these:
- something that can be managed with dithering and calibration; or
- an indication that the sensor is on the way out.
Any advice greatly appreciated.
Cheers
Mark
