My new learning applied on Messier M8 Lagoon Nebula

Narrowing RGB for both curves as levels

As mentioned in my earlier blog, narrowing individual RGB for both curves as levels in CS4 gives much better results. Using a stacked picture of Messier M8 Lagoon Nebula shows the difference.


Narrowing only RGB for curves

North America Nebula NGC7000 and Pelican Nebula IC5070

Triggered by Astrometry.net I restacked my pictures of the North America Nebula using DeepSkyStacker. Using CS4 I changed my way of editing the stacked result :

1) slightly sharpen the picture using unsharp mask
2) narrowing each Red, Green and Blue curve
3) narrowing each Red, Green and Blue level

The result is much better then my previous editing and the "head" of the pelican is clearly visible.
The pictures are taken with Nikon D7500 on TALAPO 80/480 f/6. A total of 11 pictures, each 30s with different ISO levels.

Astrometry.net


If you have astronomical imaging of the sky with celestial coordinates you do not know—or do not trust—then Astrometry.net is for you. Input an image and it will give you back astrometric calibration meta-data, plus lists of known objects falling inside the field of view.

Astrometry.net has built this astrometric calibration service to create correct, standards-compliant astrometric meta-data for every useful astronomical image ever taken, past and future, in any state of archival disarray. They hope this will help organize, annotate and make searchable all the world's astronomical information. (Source Astrometry.net)


Having troubles finding out what I recently photographed my Helios collegue Walter refered towards the website Astrometry.net. After uploading my picture, it took a couple of minutes showing all the details I was looking for. I did some more testing and each time feedback was in short matter of time given of the details of the picture.

Buran Russian Space Shuttle in Technik Museum Spyer Germany

"Selfie" before Buran OK-GLI and Soyuz landing capsule TM-19 in Spyer Museum

One of my bucket list items : visiting the Russian Space Shuttle. In the Technik Museum Speyer in Germany the Space Shuttle Buran (OK-GLI) can be seen in real life. This prototype was used for testing landings and gliding-flights. In order to do this, the prototype was equipped with 4 fan jets so it could take off and land on its own. This prototype was also the first "shuttle" to land with full automated control without any pilot activity.  Based on this prototype and the learning of the scaled models BOR 1-5 two final Space Shuttles were made. One of those was succesfully launched in space on November 15, 1988 and landed safely and automated after making two orbits.
