"Asaph Hall was about to give up his frustrating search for a Martian moon one August night in 1877, but his wife Angelina urged him on. He discovered Deimos the next night, and Phobos six nights after that. Ninety-four years later, NASA's Mariner 9 spacecraft got a much better look at the two moons from its orbit around Mars."
I managed to image these two diminutive moons of Mars from my back garden in Brisbane, around 2:00am on 9th Sept 2020.
Phobos means fear and Deimos means dread. Fitting names for the sons of a war god.:)
The seeing was very poor (I could not make out the 4 craterlets on the floor of Plato on our rising Moon) and Mars was literally wobbling like a jelly and this produced “onion ring” artefacts in the LRGB Frames I acquired.
I have overlaid my LRGB image over the blown-out disc of Mars, which I had to grossly over expose in order to register the much fainter moons. I am confident in the mag 10.62 field star and Deimos, but much less confident in Phobos, as it may well be an seeing artefact that has been stretched in processing.:shrug:
I will have to wait for better conditions to be reasonably confident of recording Phobos.:)
Tak Mewlon 180 F11.5, Tak x1.6 Extender, ASI290MM Camera. I have uploaded a Screen Capture from SkyTools 4 Imaging to provide some information on these faint suckers.
Cheers
