Thank you, Finbarr, for your totally correct information.
I have just found those 2 TYC stars on Guide 8.
By simply looking at your image, YT 1 was definitely far dimmer than what the experts stated.
Judging by your image, the asteroid might have been +13.
It would have been seriously difficult for me to see such a faint object.
What do others think?
Thank you again, Finbarr.
I am so very glad we have your image on record.
Clear skies to you.
Aubrey.
