NEOWISE with my refractor


NEOWISE with my refractor

Decided to try the refractor on the comet after a couple nights using just the camera and kit lense. The sky was pretty horrible on this night with a layer of hazy thin clouds that all but obscured the comet from naked eye. I could just make it out with averted vision. I took the images anyway hoping to capture more of the ion tail... no such luck. I took a total of 27 images that night but decided the best image came out when I stacked only a dozen.
