I would suggest that folks try to see it naked-eye (with proper filtration) BEFORE looking through the telescope or on-line. Knowing where it is in advance gives the brain too much opportunity to conjure it up. Either it's truly naked-eye, or it's not, in my book. An object that's just barely detected by 10% of the population doesn't qualify. BTW, Baader mylar is not dark enough for naked-eye use, IMO. I always couple it with a neutral density filter of either 13% or 25% transmission. The 25% seems about right, most of the time. YMMV. That said, it IS a terrific little sunspot group. :o) On 7/23/10, Patrick <paw@wirelessbeehive.com> wrote:
I just tried with a #14 welding filter. "Hints of suspicion" but nothing for sure.
