September 23, 1999
Another not-so-good day. I'm not doing as well with the barlow as I think I ought to - my prime
focus images have all been sharper. Need to keep trying, though, since it is necessary in order
to get Nyquist-limit sampling for the ETX.
Composite of 30 images of Saturn with barlow.
Composite of 20 images of Jupiter with barlow.
Just for yuks, I took a series of exposures of Jupiter at prime focus. Actually, they didn't
turn out very well either. Maybe seeing isn't so good. It also seems like I bumped the camera
while I was taking them, since the first 19 exposures look like the image on the left, and the rest
are rotated, like the one on the right.
