Things have been a bit grim for imaging here in Australia with bushfires widespread and persistent, and smoke haze and hot gusty winds affecting us badly here in Canberra, even though we have not yet had a major fire this season. A friend of mine further north has had to pack up all his gear at his observatory in the bush and bring it home.
So I cheered myself up by planning for the 2020 opposition of Mars. I will get back to RGB imaging this time, when conditions allow - I imaged using the ZWO224MC in 2018, and I will be using an 8 slot electronic filter wheel (from ZWO) so I can quickly do the RGB sequences and intersperse some IR imaging as well. I thought I would post some comparisons of IR and colour images from around opposition in 2018 to highlight the value of IR under dust storm conditions. I like the way details emerge patchily in soe mof the IR images, as if the dust was too thick even for IR in some regions.
