This is a 2-panel mosaic taken of the waning crescent as dawn brought an end to my first night of imaging with this new to me Meade 12” f/8 LX850 ACF.  The seeing conditions were pretty rough and there was a bit of haze, but I am very happy with the result. Merging the two panels of the mosaic showed that this telescope produces a remarkable flat field providing a uniformly sharp field with almost no distortion. This is a large, fairly heavy telescope that pushes the Atlas to the edge, but it performed brilliantly all night long.
