The 20″ was working well on Tuesday evening with both tracking and guiding doing a good job of keeping the stars round. Out of 41 images of NGC 891 I only threw 2 away where the stars were less round.
Due to the high altitude of the target exposures were kept short at 30 seconds and binned 2×2. Guide exposures on the STV were 1.5 seconds with the aggressiveness turned down to 70%.
Overall dimentions are 13.1′ x 2.8′ and the dust lane is showing some detail in this picture.
