, Here goes,
Takahashi sky90 f5.5 , 5mm TV Radian 100x .
From Wolf creek Crater, super dark and transparent skies Omega resolved almost to the core , an easy naked eye object.
From home only hinted at , partial resolution .
Istar 127mm f8 doublet achromat , 10mm TV Radian 100x.
From our Dark sky site beautifully fully resolved , the way only a quality refractor can .
From home , partially resolved but still nice , not as contrasty .
Celestron C9.25 f10 , 24mm TV Panoptic 97x.
From a dark site , simply spectular !!, totally resolved to the core , 'Owl's eyes' easily seen ,very very nice.
From home easily resolved to the core , just not a contrasty again and the 'Owls eyes' not seen .
So there it is , I believe that dark and steady skies are the key here and if my sky90 from an exceptional site like 'Wolf creek' or our dark sky site at Brookton WA can resolve it under the same conditions your 80mm just might
, good luck and please report back your results.
Brian.
