Small Jupiter in methane band

Clouds after clouds in Poland, but I've managed to make another short test of the methane filter. Using a filter threaded focal reducer I've reduced the SCT from f/10 to aboyt f/3-4 to make shorter exposures for the methane band - and I've got 1/4 sec with DMK21, stack of about 1050 frames. The GRS is transiting - dark in blue, bright in CH4.
