Saturn Ring Spokes...Probable ArtifactPosted By Alan Friedman |
Jim -
On shmutz on the CCD, my Astrovid camera use to have a terrible time with flecks that came off the metal 1.25" nosepiece everytime I unscrewed it, or screwed in a filter. A small can of compressed air is helpful, though sometimes a gentle swipe with isopropyl alchohol was needed. Wasn't as much of a problem with the planets which I could usually adjust position on the chip, but a bear for the moon and sun illuminating the whole chip.
