Mars - 2022-10-07 07:26 UTC - Infrared
Astronomical seeing was pretty decent when I captured the Jupiter data for the image immediately proceeding this one. My optics were starting to dew over, to I replaced the front cover, waited for an hour and found that the dew heater had completely dried the front glass on my SCT. I slewed to Mars and found that astronomical seeing had dramatically worsened. Being at the telescope and ready for another capture, I did 10 iRGB runs of 45s per filter at gain 400. In processing I found the B channel completely unuseable and the G channel not much better. I tried combining the colors anyway, and the image barely looked like Mars. The R channel, captured in IR, looked pretty decent, so I salvaged what I could.
