Description

A total of 6hrs40m of Leo Triplet, half of which I forgot to dither. That resulted in a quite noisy image. I have the impression of adding the second 40 frames, this time dithered, did not 'repair' the noise entirely. You still get stuck with noise from the first batch. See the website for a comparison.

Anyhow, I'm happy with the result and the detail in the galaxies. Also, depending on monitor settings and different processing version, the tidal stream is present over a few lenghts. For this version I choose to make the background a bit darker to get rid of noise patterns.

Clear Skies!
