About this image

1^st ever comet imaged through Telescope and processed.

Reprocessed the same data I uploaded yesterday – I’m still learning and an Astro mentor of mine suggested that the comet was too bright/saturated in my previous version – hence this new version.

Comet image processing is challenging but I’m getting here, slowly but surely :)

This image is of the stacked stars and stacked comet data in the one image, layered in PS.

Processing; Deep sky stacker, Pixinsight with final tweaks in Photoshop, Lightroom + Topaz DeNoise AI.

Clear skies all.
