Today I fixed the position with Hine's Planetary book.
At 168x (15 mm Panoptic) with OIII- filter with averted vision I see it very faintly glowing, but clearly. At good moments I can even hold it.
Is the wheather better, or am I fitter than yesterday?
Sometimes the Edge appears brighter than the inside disk.
Also seen the friens's 20" f/5, but more difficult there.
This is a magic planetary!
