Nice, Ray. I don't know any planet imager further north than me, so I suspect I've got it fairly good for Mars?...52 degrees maximum alt. for me here right now..
thanks John. You have certainly "made hay while the sun shone" this Mars season and it looks like being further north is an advantage. Altitude has been particularly important down here during the warmer months - watching Saturn rise up through the murk is instructive and its has been pretty useless below about 50 degrees. have imaged successfully in past down as far as 21deg, but clear conditions that low seem to be more likely in colder weather.
maybe will have to move to Darwin for the next Jupiter season...its going to be a cruel 34 deg max altitude down here.
There has also been a pretty sharp cutoff in seeing when the 200hPa winds get above about 45kts - it's not necessarily good if winds are lighter, but is pretty much guaranteed bad if they are above.
