The R-athon is a challenge to find the R variable in each of the 88 constellations.
The goal is to do this with off-the-shelf digital cameras, such as the Kodak Z612, Kodak Z1015, Panasonic Lumex etc.
For starters I have chosen three examples: R Cas, R Cet and R Lyr. Three down, eighty-five to go!

R Ceti, this Mira variable in Cetus is not nearly so famous as Mira! But while looking at Mira why not check out R Cet? Contrast problems here. | 818k | v. 2 | Nov 7, 2011, 8:12 AM | Richard DeCoster | |
