The Pleiades Messier M45

A total of 40 minutes exposure from the Pleiades Messier M45 Open Star Cluster. The 80 pictures, each 30s and a mixture of ISO setting between ISO800 and ISO6400 are stacked using Astro Pixel Processor. The result was saved as a Tiff32bit file and edited using CS4. Depending the gamma setting the dustclouds appear nicely and bright.
Pictures are taken with Nikon D7500 on TLAPO 80/480 f/6 on EQAZ6 GT mount.

Andromeda Galaxy M31, M32 and M110

For stacking my pictures (40 pictures ISO6400 each 30s) I did not use DeepSkyStakker but Astro Pixel Processor.  The outcome is a fits file which is converted to Tiff 32bit and edited with CS4. The final results shows the Andromeda Galaxy M31 and both M32 en M110.

Spiral Galaxy NGC891 New Edit

I used a different way of editing my pictures; mainly converting is changed. I converted the fts files to tiff32 rational using DeepSkyStakker and made editing possible into CS4.
The result is much better then starting within tiff16.
