I turned the scope onto the Moon while I was waiting for the GRS to appear on Jupiter. I think these are the best Moon images I have got to date.
All shot with DFK21afo4 on the 14" LX200 cooled to 5 degrees below ambient. I need to work out the imaging ambient temp about 8 hours in advance, if that is possible. Because the primary was so cold after a period of time it dewed up.
1= Capernicus
2 and 3= Plato
4= Clavius
5=Mare Imbrium with the pair of craters, Helicon and Verrier that are 25km and 20km respectively.
The temp requirements must be different for the LX 200. I have found that if my mirror is more than .5 C above or below ambient I get noticeable degradation in the live image from my DMK, mind you, it is very early days for me with active cooling but that has been my experience thus far.
Trevor all I can say is that perhaps the images could have been better if the mirror was at ambient, or because its an enclosed system it may not be so critical.
Unless there were 2 identical scopes side by side, it would be hard to test this, as we know seeing can be so variable.
