Makes me jelous of my mate whose back from the States for a month, he lives at Sunspot, New Mexico, a solar observatory that is 9000ft ASL
http://www.nso.edu/
where he works as a PostDoc solar Physicist. If I were him Id certainly have my rig there, and the great thing is, being a solar physicist, he only works during the day, that would leave the nights open for excellent imaging
Oh well one can only dream.
Getting back to RCs, to be fair Brad Moores pics arent too far behind this one
http://www.southern-astro.com.au/
but look at the time, 28.5 hours on an image!
What does make the cassegrain scope's image all the more impressive is that Eta carina wouldnt be very high at its location. 47deg N!
