Oblique viewing phenomenon?Posted By Mark Clegg |
Bill,
I have also seen this several times with my Ethos.. but in the case with me it was moisture build-up on the eyelens itself, I simply back off and fan the eyepiece a few seconds with my hand and it dissipates. Heat from my eye, or a combination of heat from the eye and cupping around the eyepiece itself to sheild off stray light may explain the moisture build-up (especially during observing when the moon is so bright)
