2020  8 26.74   M 15.3 AQ  40.0L 261  0.2  5/           WYA  Walcha, NSW
(Difficult. Visible in periods of good seeing, close to star but resolvable.)

(Already too faint to see. They say it looks stellar, so I estimated the limiting magnitude of stars in focus.)

(Very faint, stellar object. Motion close to magn. 13.5 star obvious within 5 minutes.)

(Faint stellar object, confirmed by motion over a 1-hour period. Limiting stellar magnitude: 15.5.)
