This second one is the same stacked data, but I used the VeraLux Suite’s stretching tool. A bit overbaked but it brings out some more detail.

Four nights of imaging Thor’s Helmet using a Canon EOS R6mkII and Tamron SP 150-600 f/5-6.3 G2

A lot more work and not as good as the dedicated, air-cooled astrophotography camera and real telescope.
