Sun H-Alpha Sunspot 2727

Picture of the Sun today with Sunspot AR2727. This picture was taken using Nikon D7500 on Coronado SolarMax 3 70/400 f/5.7 DS/BF15 with setting ISO3200 and 1/100s. Final editing using CS4.

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.

Renewed editing of Messier M52 and the Bubble Nebula. Total exposure of 300s and including darks. Initial stacking results in Fits 32bit file. Using DeepSkyStakker to convert into Tiff32bit  rational file which is edited in CS4.

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.
