Wade;
You are very welcome, it is always great to hear from a satisfied "customer". I had a request to provide these as pdf files, but I don't have a program that will do that and Allister said that it is not necessary. I give permission for someone to use the online files and make them into pdf's if someone thinks that would be more useful.
Clear Skies;
Steve Coe

I can see M79, just barely, from my NELM 4.5 backyard.
In a 25x100 binocular, on a very good night, it is scarcely visible as an averted-vision ghost. It's very tiny and is seen only as a subtle variation in the background brightness of the sky. Tapping the tubes was necessary to confirm it.
In my 6" Mak-Cass, it's visible in direct vision, but only as a faint and small spot against the background. Throwing magnfication at it only caused it to thin out and vanish.
It's no show-stopper. 
I have yet to glimpse Hind's star, but I'll keep looking.
How does the color compare to Herschel's Garnet Star?

Herschels Garnet Star (Mu Cephi) is brighter and not as red. In my opinion, closer comparisons to R Leporis are V Aquila, V Hydra, and T Lyra.

Hi Vic;
According to Brian Skiff at Lowell Observatory, V Hydrae is the reddest star in the sky. If I remember correctly it is the only star with a B-V value of greater than 5. It is "underneath" Leo, so give it a try in the Spring.
They are fun;

The link I posted earlier, "The Top 10 Very Red Stars", notes three Skiff B-V 5.5 stars (and one 5.8!) I pulled the old May '98 S&T to reread some of Brian's commentary. He mentions that V Hydrae may be making the transition from red-giant to a planetary nebula! Like you, I've followed several of my favorite carbon stars for many years. I like to include them when doing outreach at schools and at other public venues because they always seem to generate real excitement at the eyepiece.
