Mimas!
By Bill Arnett

The seeing was 9 out of 10 tonight in Redwood City. I took the opportunity to tweak my collimation. I turned one screw about 15 degrees and another about 5 degrees. That tiny adjustment made a BIG difference. I was easily able to see white ovals on Jupiter that I had not seen earlier despite careful searching. And the appearance of the Galileans was dramatically improved: they went from disks with spikey extensions to disks with slight wavy edges. I've always heard (and believed) that collimation is important with SCTs. Now I know from personal experience that it is exceedingly critical and well worth the effort!

I also saw for the first time a white oval in the STB. There's more to Jupiter than meets the eye on first glance!

But, as usual, Saturn was the star of the show. Wow, when it is good it is REALLY GOOD! Cassini's Division was BLACK. The C ring was trivial. I could see some variation in the southern polar region of Saturn itself but I couldn't really call it banding. (Of course, there is an obvious equatorial zone distinct from the polar zone; I'm not sure of the correct terminology.)

And I actually saw Mimas from my backyard! It wasn't easy; I only saw a flash about 10% of the time. But was just in the right place. I count it as a confirmed kill :-) (The four biggies were easy; Enceladus was not visible at the time, behind the planet.)

(All the above with a 12" LX200, as most of you know.)
