Imaged Mars in RGB and IR with an ASI224MC on the morning of October 4, 2020. The conditions were good for my neck of the woods with average seeing and transparency. Mars was only two days from closest approach and showing a disc ~22.5 arcsecs in diameter at magnitude of -2.5. The dark albedo feature to the left of central meridian is Sinus Meridiani and to the right is Syrtis Major.

Imaged with a C8 Evo, ZWO ADC, Baader IR 685nm pass filter, and ZWO ASI224MC. Imaging train was configured to give ~F/20. Image capture using Firecapture with gain set at 275 and an exposure of 4.5 ms. Stacking in AutoStakkert3 (best 15% of ~45000 frames captured over 240 seconds). Wavelet sharpening and conversion to black&white in Registax6. De-rotated and combined 4 images in Winjupos.
