received good 891 data (Halifax)

On 3 September, the BGO robot tried to image NGC 891 (Caldwell 23) for me, again. But something went wrong and I did not get a full set of data. And that was in an effort to improve on the first run on 20 August where there was a significant gradient. This one worked out very well. Thank you BGO!
