But widefield is for sissys Renormalised..
Fred - From now on I'll just fire up the heater at full stick and leave it there all night... that might be the fix I've been looking for... The C11's mirror flop doesn't appear to me to be all that bad... Mind you, I've never imaged past the meridian with it.. (Im yet to run a single sub longer than 5 mins through it... so I suppose im hardly in a position to comment on the flop factor

)
