Description

Three Days Leading Down to Mars, C/2023 E3 (ZTF) on 08-09-10 February 2023 Mosaic (North is Up, west right).
Fun to do, but I'll need more planning and practice.  24 hours separate each of the three panels as the comet moved @9.3arcmin/hr (Feb8) down to7.4 arcmin/hr(Feb10).  All three panels were shot with identical system using a Rokinon 135mm @ F/2.8 and capturing around 50 x 120 seconds each.  Mars of course is the bright orange overexposed star like object in the lowest panel.  Interesting to see the changes in brightness in the comet and its tails over the three nights, however this might be as well do to the variability of the seeing conditions and my PixInsight processing limitations.

Since the panels of the mosaic are centered nearly  exactly 24 hours apart, there is a noticeable slow down as the comet separation decreases, while the comet traveled southward.  Since the image scale of the mosaic has been reduced to 50%, or 14.14 "/pixel and Mars is 9.6 " in diameter (Feb10th), by interpellation, Mars would be less than 1 pixel in size if imaged purely with this system.  Wouldn't be able to see the rovers at this scale.
