Europa puts a beauty mark on the Great Red Spot

I was cruising facebook some weeks back and found one of those “On this Day” which had me wondering what happened.

So I went and checked my annual gallery for 2013-2014 and found it wasn’t finished and posted!😨

So, without ado, here’s my 6 year old post made of 3x derotated images with a composite single image of the shadow and moon.





Animation

WinJupos reference

Uranus and 5 moon animation

Taken over the span of 36 minutes on September 28th, 2014.  I was able to image; Titania (mag. 13.9), dimmest Miranda (mag. 16.5), Ariel (mag. 14.4 ~Pluto's brightness), Umbriel (mag. 15.0) and Oberon (mag. 14.1).

First here is the untouched animation showing Uranus at the same exposure of 1sec.

Next I added the color and properly exposed Uranian disk.  I shot at a nominal focal length using the 2.5x powermate and the soon to be older Flea3 camera.  Next time I'd love to get the QHY and 5x Powernate!

Also relevant, my 4 year old sounded out Uranus to...

YOU

RAN

US

I love it!

Also the fact i can image down to 16th magnitude at this focal length has me wondering about splitting Pluto and Charon!

Akule's 1st *real* shot at Saturn

After some long streaks of poor Astronomy weather but good people weather (aka warm and breezy) we finally got a break here in NC.  I put a simple indoor/outdoor thermometer on the mirror to measure the air and mirror temp.  I need some active cooling.  I couldn't keep the scope less than 2.5°F above ambient.  Still, the forecast of 4/5 seeing worked well and I am VERY happy with the results.

As always, click to zoom and here's the rest of the Saturn 2011 season.

Also, here is the telescope's vital stats, details, construction and photos

Flea3 tests on FW800 in Linux

Testing my PGR Flea3 FL3-FW-03S1M-C in Ubuntu 9.04 Linux on a DL380-G5 with the PGR FirePro FWB-PCIE-01 - 1394b PCI Express Card
With this setup I was able to achieve 102fps, 16bit (12bit stuffed) and the full frame size.
