Visual impression

  • Capture notes:
    Excellent seeing was forecast for a brief 3 hour period after sunset
    and before a drop back to average seeing.
    Fought equipment issues but got tons of great data, including a mutual
    moon event.  I wasn't sure what settings to use so I ran my regular routine
    hoping for something.

    Processing notes:
    Initially I thought I had caught the dimming of Tethys, but I think that
    because I start captures at dusk the brightness of the sky washed out the
    fainter moons like Tethys.
    I'm still not 100% happy with my routine and feel that with great
    seeing there's always more tweaking to be done!  Take good notes
    everyone!

    Observing notes:
    I didn't spend anytime visually observing as the equipment issues with the
    laptop and being excited for great seeing kept me distracted until the
    seeing went back to the usual average.

Weather:Seeing: Perhaps 8-9/10 judged on Saturn only, the collapsed to 5+/10
Transparency:4/5 with a small T-storm cell ~15 mi away and HUGE one 45mi away which was VERY visible despitenot having any haze or clouds nearby.  STRANGE
Forecast: Small window at dusk of 5/5 Seeing!

Comments:Great weather locally, but horrible in surrounding areas (see Transparency report!).I made great work of some of the local seeing on Saturn and was excited for a mutual moon event of Tethys and Mimas.I am not sure I captured it or not.Then the inevitable happened I ran out of disk space on the laptop!  Wait that was after the crash, yes linux crashes too!Sill no remote control of the laptop via the computer or long HC cable.I grabbed an external USB drive (formatted fat32) but recording at 15fps was not an issue.Moral of the story is even a short window of great seeing is worth the threat of storms and always be preparedwith a clean hard drive or spare usb drive nearby!

Fun with dancing Saturnian moons

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

I think I'm the kind of person who doesn't like strong opinions.  It doesn't matter if I agree with your opinion or not, it's not factual, it never will be 100% factual and I don't care for it.  That's probably why I hate politics.

I've always loved facts, provable facts of nature and things concerning science.  

Over time, I found that most facts are mostly reference and it was the creation of and discovery of new things that intrigued me.

"A good friend once told me you are our memory
without them we equal nothing
And all I can see is the place I wanna be
Suddenly my life was so free
Leaves at my feet, blown to the ground
their echoes are reaching my ears
Nights coming fast, suns going down" - A7x
