Mars with Phobos & Deimos (E=19s Nov 6 2

Mars at 19 arc-secs in diameter showing both of its small satellites on Nov 6, 2020.

Mars is overexposed to bring out its difficult satellites.  This photo is heavily processed.  The original stacked photo was noise-filled from the glare of Mars.  The weak satellite signals were isolated and intensified, the glare noise was then removed.  Mars is displayed at its actual diameter.  Deimos was at its extreme elongation, Phobos less so.  Phobos though technically brighter, had less signal owing to the more intense glare and so appears fainter than Deimos.  20cm SCT, F10.  Exposure 50ms x 380 frames = 19 seconds and taken through an open window.

Jupiter's Satellite Amalthea 2.jpg

Jupiter's difficult to image satellite Amalthea.

Jupiter, Europa and Callisto are all much overexposed in order to bring out faint Amalthea.  Exposure info not recorded.

Neptune with Triton.jpg

Neptune and its only satellite that can be imaged with most amateur equipment.

Exposure information not recorded but similar to most imaging requirements.  Colored.
