2003 Feb: Clear frosty days and productive nights with some haze. Mike Collin's vs TAV J0218+507 And  is even more of an IR object emitting beyond Ha at 656nm  [than R Cas] so as to be currently largely invisible to the eye!

Two other Collin's variables, topping the TAVS list on BAAVS homepage also included, as well as CO UMa, TY Tau and T Tau [Hinds' Variable Neb central star] - latter with strong Ha emission line.  Three faint PNe also recorded here during these sessions.
