Comet 12/Pons-Brooks, 3/27/2024, 20h50m EDT

March 29, 2024 by

Telescope/Camera: Seestar S50

Filter: None

Exposure: (60 + 60)x10sec (20min) saved as FITS

Average Light Pollution: Bortle 8, fair transparency at dusk

Software: Nebulosity, Photoshop

This is another quick grab of Comet 12/Pons-Brooks before it got too far down in the before it was lost to the haze and light pollution over my western horizon. This images is the combination of subs taken over a 10-minute period through two Seestar S50s operating in parallel. As the images were being taken the comet dropped from 19 degrees over the horizon to just 17 degrees. Although the comet was an easy target for the Seestar, it was really tough to see in my 10×50 binoculars.

Well, this was fun. I am fortunate enough to own a pair of Seestar S50s that I usually use in in parallel recording data on different targets at the same time, often a series of variable stars. However, in this case I wanted to grab as much data as I could on Comet 12/Pons-Brooks before it was lost to the haze and light pollution over my western horizon, so I used them to image the comet simultaneously over a 10-minute period starting at 9:00pm EDT. This resulted in 60, 10sec exposure from each camera that were then aligned and combined in Nebulosity and processed in Photoshop. Given the challenging conditions I am delighted with the result.
