Yep, between the smoke, monsoonal weather and the brightening moon, this was probably the last chance to image comet C/2017 K2 PanSTARRS as it slips too far to the south.  As it were, I had to image between the coniferous trees for this capture and cabin still able to save 92 x 60 second exposures for stacking.  Luckily the smoke form the "Oak Fire" had decided to go westward and the night's seeing & transparency were superb.

Several notes about the image..  The glaring blueish artifact in the lower left-hand corner of the image is from the 2.6 magnitude star (third brightest in Ophiuchus) zeta Ophiuchi, only about a quarter of a degree off the field.  This star is actually a "physically magnificent"  blue white star of class O9.5 about 450 ly away and is responsible for illuminating much of the hydrogen alpha emission cloud seen in this image.

The color of the image is fairly natural (added saturation of course) since I used the PhotometricColorCalibration tool in PixInsight for both the comet and starfield using the appropriate white reference.  Not bad for an OSC camera on such low altitude. 

Comet C/2017 K2 PanSTARRS is fast becoming a southern hemisphere-only object where it is expected to brighten slightly as it approaches perihelion in December 2022.
