Hi all:

Mars is about 1/3 the size of Saturn's globe, yet there's still detail to image. Dia. = 6.8", CM = 17, seeing = 5.5/10, 10" SCT, F/40. This is getting interesting as Mars approaches 6", then 5" and finally 4"?

Cheers, Dan smile

Lots of detail for 6.8 arcsec! Heres a
comparison vs quick simulation in Starry Night.
Pretty good match. Will be interesting to
see at 4".
