[vsnet-chat 5331] Re: (fwd) R Cas and Comet Ikeya-Zhang



     Is this not caused by the extreme red color of R Cas in the 
unfiltered CCD?  Or am I missing something here?  The star is 
R ~5.5 when V is ~10 (see Kornilov et al. 1991TrSht..63....4K),
so the observation seems to be about as expected.
