Comet 46p/Wirtanen

Comet 46p/Wirtanen passing between HR 1419 and HR 1390.

This was a difficult one for me, both to capture and process. It was my second attempt due to inclement weather. Seeing still wasn't great with there being a thin scattering of high clouds and an incredibly bright moon, but I am really happy I had another chance at capturing this object.

For this image, I ended up using only 42 of 150 subs due to quality. Color was also incredibly difficult to work with due to the amount of sky glow in the images, but I think I managed to balance it out, and stay true to the natural color of the comet.

At least I hope so.

    Beautiful image.  We had cloudy weather where I live for all but about 2 nights in December.  Nice that somebody got to see the thing...

    Thank you! I’m glad you like the image.


    We had a few clear nights, mostly toward the last days of December. Tried taking advantage of them as much as possible. Was especially eager with the month of November being completely clouded out, or too hazy for good seeing from all the wild fires here in California.


    Rains have picked up again. Should rain for the next week or so. Going to use the down time to work on the scope, revisit old data, and make a library of bias frames for each camera.
