Jupiter With GRS (Sep 20 2012)

Towson, MD [Location: N 39° 23' W 76° 36']
Transparency: 3/5
Seeing: 3/10
RV-6 Newtonian (150cm f/8) with TeleVue PowerMate 2.5x
Camera: DFK 21AU04S 1/76 sec exposure, 30 fps Registax6: 35 frames from 1925
CM I: 7.5°
CM II: 175.5°

The Great Red Spot is obvious albeit anemic, but the image seems a little 'mushy', a little concerned that perhaps the focus was not perfect. Other photos of Jupiter around this time show that the 'little red spot' is in the SSTB almost directly above the Great Red Spot, so a little disappointed that I could not capture that.
