Description:
Squeezing the photons again tonight ...
Saw “something” at 22x and 30x too. Extremely faint oval nebulosity at 110x
with averted vision and at extreme edge of detection. 146x made it too faint
and disappeared. Not sure if I actually saw this PN, but I checked and doubled
check the detail printed chart and star pattern and it’s got to be it!
