Description:
Very bright with the use of an OIII filter and 342x magnification. I.1297 
appears as a bright round disk with a slightly brighter N part. The edge is 
sharp. I had seen a darker middle and extremely faint hints of annularity 
(observation confirmed by comparison with photographs). Also the south part 
appears to be fainter than the north part of the tiny ring. Diameter ~15" 
(many different sizes in various sources). No CS seen. Nice but, it needs 
higher magnification and very good seeing.
