Picture of Saturn yesterday evening with bad seeing. No really a sharp picture. Setting ZWO224MC on TAL200K f/8.5 with ADC and Barlowx2. Stacking with AutoStakkert! and final editing using CS4.

Jupiter and yellow filter

Picture of Jupiter yesterday evening. Seeing was bad, so pictures are not sharp. 

Setting : ASI224MC camera on TAL200K f/8.5 together with ADC and Barlowx2. I used this time also a yellow filter to boost up the contrast. Each picture is the result of 60s AVI movie which was stacked using AutoStakkert!. Final editing using CS4.
