Extraordinary rich red, no companion noted, very much living up to the name 'Crimson Star', faint, challenging to find, at about 10th magnitude currently using TYC 5329-0258-1 as the comparison star (AAVSO reports 9.4 magnitude and fading on Sep 13th)

A dramatic rich red truly justifying the moniker Hind's Crimson Star, near 11th magnitude tonight, the faintest this star has been in over a decade (latest AAVSO observations indicate magnitude 10.2 and fading a few days ago)

A beautiful deep crimson tonight, clearly earning the moniker Hind's Crimson Star, one of the reddest stars to be enjoyed anywhere in the sky

Very red tonight! Must have caught it near minimum, a deep coppery red, as red as any of the carbon stars, beautiful! (AAVSO latest magnitude is 8.4 on Dec 26th)

Fairly bright, red-copper color, stands out well in the field, must have caught it near maximum as R Lep can be much more deeply colored when near minimum
