Yesterday I took delivery of a new set of RGB filters from Astrodon,their new I-Series which look to have very good properties. I was keen to try them out,and the seeing cooperated nicely this morning - spoiled only by a thick fog that rolled in about halfway through and limited my last series of captures (showing the GRS) to below 20fps.
The Astrodon filters give me a brighter image in red and blue,this morning before the fog I was able to capture at 40fps(red),50fps(green),40fps(blue) and still get a histogram that was about half full. I've made a conscious effort this year to trade off some image brightness for increased clarity,and as long as I get to halfway on the histogram I'm happy.

Con las primeras luces del dia y tras el paso del temporal la atmosfera estaba relativamente estable.
La primera imagen incluye Infrarrojo (filtro W-25 en canal R),la segunda es con los RGB y bloqueo de IR. Tambien he aplicado en las dos el sistema L(R)RGB.

This is my first go at Jupiter this singularly unfavourable apparition for us in the UK (someone has to do silly things). I wonder if this is the first high-res image of Jupiter from here this year. So far as I know it is.
I used a far (by amateur standards) IR filter, plus a low focal ratio to keep the frame rate high (30 fps) to combat the turbulence at 17 deg. alt. 3500 frames were captured in 2 mins.
Surprisingly, it shows something - the turbulence in the SEB, the big barge on the NEB and plume prec. it.
C11 - I can't get the C14 on it until later in the season.
