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

    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! 
Equipment:Ubuntu 9.04 Linux and custom coriander on Lenovo T61 (Cepheus)8" Celestron C8i SCTLymax Cat CoolerDMK 21AF042.5x PowerMateAstronomik LRGB filtersTrue Tek Color Filter Wheel with visu diag
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!

Loving husband, proud father, computer geek, astro freak, music lover, sports nut and general fun-loving guy

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
