Decided to skip Low Gemini and choose Corvus, so as to give those down in Southern Oz, a chance to report Doubles located at higher altitudes .
These are the ones selected by myself and Eugene for March..Weather has been lousy for most so give some, or even one of these a go; especially if its light polluted for anything else.
Use this for co-ordinates..
