Flame Nebula NGC2024 with COAST


Learning from my first picture M104 with the COAST telescope in Tenerife I was able to edit my second picture, NGC2024 or Flame Nebula. It was more complicated then expected as the nebula is rather faint. Again, RGB pixels were alligned and gamma boost up. DeepSkyStacker was used to convert from Fits to Tiff and final editing using CS4.


M104 Sombrero Galaxy with COAST

The Sombrero Galaxy M104 is my first picture with the COAST telescope in Tenerife. Using the software from Telescope.org it was possible to finetune the picture. After alligning the RGB pixels the gamma range was adjusted. The Fits files was saved and DeepSkyStacker was used to convert the picture to Tiff format. Final editing with CS4.

First picture with COAST telescope on Tenerife

As part of the OpenLearn course I was able to make my first picture using the COAST telescope on Tenerife. This robotoc telescope is located in the Teide telescope parc in Tenerife. It's a 14inch Celestron and the request of pictures happens through the Telescope.org website after registration. My first request was M104 Sombrero galaxy. I used the standard setting with exposure time of 120s and standard RGB. A couple of hours later the sytem confirmed my request and I received my first picture using a remote telescope. I can not compare yet with my TAL200K but picture looks quit sharp, knowing it's almost full moon.
Some learning to do on working with timing,.. and downloading and editing Fits files..

New record for Parker Solar Probe


Nasa's Parker Solar Probe realised it's fourth close approach to the Sun. This fourth encounter resulted in breaking the speedrecord as is now 393044 km/h and the closest distance to the Sun of 18.6 million km (as reference Earth is about 150 million km located from the Sun). As the probe is getting closer, temperature is increasing up to 612°C but equipment is kept cool up to 30°C.

Lecture by Werner Poets at Mira

Selfie with Werner Poets
This evening I attended a lecture by Werner Poets @ Mira (Grimbergen) covering the special theory of relativity.  The lecture started with the explaination of the two postulates : the  speed of light in vacuum is the same for all observers and the laws of physics are the same in all inertial frames of reference when moving at constant speed. 

Starting from this Werner Poets used graphs to explain the theory and ended with the time dilation and length contraction when moving at speeds near the speed of light.

The lecture was sold out and he repeated the lecture after the first one as many people could attend the first one.

This first lecture will have a second part in september discussing the general theory of relativity and black holes;
