Thanks guys, I'll have to check the collimation, not much I can do about seeing conditions at the moment, I remember also that there appeared to be quite a bit of condensation on the 2" eyepiece to start with and also the main lens didn't look clear when shining a light on to it,not sure if there was moisture on the inside or outside of the lens.All to do with cooling down time I would think.Just wondering also,if it is advisable to have the dew heater working flat out to warm the dew cap near the main lens, or whether its better just to let the whole thing cool down to ambient temperature.I read that the metal surfaces of the telescope cool much more than the air temp,which would transfer to the glass of the main objective.If thats the case moisture in the warmer air would always condense on the cooler lens.Am I rambling too much here?Cheers.
