Description

Just Neptun itself, crop & zoom by 400 % ( Fitswork)

This version does not reveal the moon Triton, cause I wanted to show a homogenious natural surface

of Neptun.

( of course still no surface details, impossible with a 12" mirror and also Neptun at max. 30° elevation over the horizon at my location)

At best, as the maximum illumination is slightly offset from the centre, one could assume the direction towards the sun.

At 400% we see clearly slight undersampling artefacts.

The high angular resolution of the 12" mirror would require smaller pixel sizes to show a smooth image.

But the disadvatange of using a cam with a smaller pixel size would be a lower sensivitiy.

Atik 383L+ C = 5.4 square micrometer /pixel, 16 Bit dynamic range

ZWO ASI 120MC = 3.75 square micrometer /pixel, 12 Bit dynamic range
