Mars at 12:06 am this morning. Best of the evening. Images taken from about 10-11 pm were dismal in comparison, seeing apparently deteriorated for a while and then improved.
Celestron Nexstar11 telescope, 2.5X Powermate, DMK21AU04.AS camera, 60fps luminance channel, 30 fps RGB channels, aligned and stacked with Registax5. Transparency very good, no wind, 18 deg. F. Seeing was about 6 based on the airy disk when I rechecked collimation for this set.
