Equipment Details:

Nikon D3500
Hoya Starscape LP Filter
Optolong L Pro
Skywatcher SA mini
Nikkor 70-300
Sigma 70-300

Post-processing Details:

Comet was about 20 minutes of data 41x30s iso 400 at 135mm
M33 was about 12 hours of data reprocessed and blend at 250mm

Image Details:

Comets are fascinating. 12P Pons-Brooks is a periodic comet that visits Earth once every 71 years, and last time it was here it was 1954. Here you find it in conjunction with the M33 galaxy.

This shot was very difficult to take and prepare for as the North-West section of my sky is very light polluted and I had to extract and reuse old data of M33 to create the perfect shot.
