Ful RES:
And animation!
And facebox labels!
Capture notes:
Seeing makes the rings quiver and nowhere as good as a few nights ago. I still have not touched the focus or collimation, but did capture Regulus in Red. My regular routine 1/15s per channel (still all channels full gain). Initially the fps were set wrong as I work the kinks out of this setup. That was not as bad as it sounds, I lost some frame per channel, but it was only 180s per channel. Fixed for the 2nd run at 300s per channel which is what I really like on Saturn especially with variable seeing. Seeing degraded towards the 3rd cap, despite more cooling between 2 and 3

| Weather: | Seeing: 7/10 Transparency: 3/5 Forecast: Initially, 4/5 for both, but recently clouds crept in, which didn't appear at all in dusk. I hope the seeing holds! |

| Comments: | Bad drift even after a rough leveling of the tripod and auto-two star eq align. I didn't check the errors per axis, but I can't survive the drift without a reposotion of Saturn after 1 - 2 minutes, which is only annoying as I've yet to get scope control in Ubuntu 9.04 Jaunty jackalope in Kstars/Indi. Took a break from Saturn imaging ~2140 for re-cooling of scope... not sure it helped, but back imaging at 2202 |

wow very nice & exciting
ReplyDeleteWow great detail abot this image. I had the same problem with the drift.On my scope the weight was off a couple of inches which fixed the problem.
