Good Jupiter and some questions

[riklaunim]

Got a short breake in the clouds today. For some strange reason the seeing was from very good to epic SCT 8", Basler Ace acA640-100gm, GSO 2x Barlow for f/20.

f/20 RGB and Ir-RGB at 18:40 UTC:

f/20 RGB and Ir-RGB at 18:47 UTC:

Ir (blurred), Red, Green, Blue channel:

Methane Band. 18:58 UTC f/20 at 1 sec exp and 19:04 UTC f/10 at 0.5 sec exposures, with darks

Note the strange spot over GRS:

I've also wanted to check if IR tricolor imaging could get some colors. There are Astrodon and Hutech sets for this... I used Pro Planet 742, 807 and RG1000 - first two overlap, and second is far away with lower transmission so far from perfect:

RG-1000, Pro Planet 807, Pro Planet 742 false color composition:

Pro Planet 742, Pro Planet 742, Pro Planet 807 false color composition:

There are some colors with the RG-IR8-IR7 version where the GRS is orange (and red is RG). IR7-IR8 doesn't give much color. Both overlap so colors are equalized. The filters I'm talking about are:

* http://www.astrodon.com/products/filters/near-infrared/

* http://www.sciencecenter.net/hutech/idas/type4.htm

Anyone has any comments if IR/NIR false tricolor imaging could give enough color difference? Methane will absort differently in the filter bands, and also amonia can add a bit. Something else? Vendors do not have any user cases except of NASA equipement flying by the Jupiter and doing false color IR

And now I'm sick, or more precisely my head is going to explode.. :| I hope I didn't caught any Jupiterian flue
