The Cassini division was real crisp and clear. I saw some kind of gap happening outside of Cassini. It was real unsteady and was only visible for short times so I can't be sure what I was seeing. It could have even been some kind of turbulance. -----Original Message----- From: Chuck Hards [mailto:chuckhards@yahoo.com] Sent: Tuesday, January 21, 2003 1:51 PM To: utah-astronomy@mailman.xmission.com Subject: RE: [Utah-astronomy] Saturn --- David Dunn <david.dunn@albertsons.com> wrote:

I spent most of the time Friday night looking at Saturn without a filter. I used my 8" f/7. It was real steady at 143X. I had the Enke division (might have been the minima) popping in and out of focus. I was too impatient for the 284X view.

Dave, are you sure you you saw the Enke gap (in the A ring itself), and not the Cassini division? 143X, IMO, is insufficient magnification to see the Enke division, although at that power, the Cassini division (between the A & B rings) is obvious. Saturday night, at powers up to 300x (near the diffraction limit for my 6") there wasn't a hint of the Enke gap or minima, though the image was rock-steady and crisp.
