This is the animated .gif of the two together.  This is with a x2 barlow and as you can see, the absolute pixel size of Mars is small and getting smaller.  We have heard of other imagers using up to x5 barlows (with a subsequent 25 times less light than no barlow at all), so that means you need a bigger telescope.  That means I still need a bigger telescope.<br \/>\nSyrtis Minor is approaching the centre with Hellas towards the bottom left and Syrtis Major on the far left.<\/p>\n<p><a href=\"https:\/\/starlightcascade.ca\/blog\/wp-content\/uploads\/2020\/11\/mars20201114.gif\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/starlightcascade.ca\/blog\/wp-content\/uploads\/2020\/11\/mars20201114-299x299.gif\" alt=\"\" width=\"299\" height=\"299\" class=\"alignright size-medium wp-image-9300\" srcset=\"https:\/\/starlightcascade.ca\/blog\/wp-content\/uploads\/2020\/11\/mars20201114-299x299.gif 299w, https:\/\/starlightcascade.ca\/blog\/wp-content\/uploads\/2020\/11\/mars20201114-150x150.gif 150w\" sizes=\"auto, (max-width: 299px) 100vw, 299px\" \/><\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Mars on the cold evening of Saturday Nov 14th.
