Mars And Neptune 12/10/18
This was taken 24 hours later. Noting that the magnification has changed from the previous images, but observing the positions of the stationary background stars, Mars' significant movement is obvious. This more detailed image is the result of stacking about twenty, thirty second, individual exposures. An equatorial mount was needed to avoid star trails.
