Description:
This is one of my most chalenging observations. Many times before
tried without success even under very good conditions.
--
This time under eceptionel transparent skies (fog in the valleys
blocked residual light pollution) and wildly structured Milky Way
field found with Uranometria an fixed exact position with DSS print.
--
- 24 mm WF (108x) + OIII: nothing
- 15 mm Panoptic (168x) + OIII: nothing
- 14 mm Meade UltraWF (180x) + OIII: 3 times in half hour of trying
   an extremly faint circular glow popped up with averted vision.
--
The next night under same conditions I saw it again and again, but
could hold it at 10% of time only. The observing fellow next to me
confimed sighting.
--
One of the really difficult Abells!
