Using similar charts as you,I consider I have observed it with my 16"from my dark sky site,here in the Sunshine Coast Region on a night of excellent seeing.
Wes (Zubanell) using his 20" SDM uprated dob and other users of large SDM telescopes at a gathering of said group,had a positive observation of it within the last year.
Will give it another go in the near future.
Well done on your observation.
Cheers
