Today I integrated the existing images of the Leo Triplet from 2020 and reprocessed them. The result can be seen quite well.

M66 – Leo Triplett

 

A total of 161 exposures with the Nikon D5200 with Kenko 1.5 converter and the Skywatcher 130/650 PDS at ISO 800 and 75 exposures without the Kenko at ISO 1600 (plus corresponding darks, bias and flats) – each with 45s – were used for the image in the new image. Total exposure time is thus 177 minutes.
