Unbounded Universe: An Unforgettable Evening with Govert Schilling on the James Webb Space Telescope.

The James Webb Space Telescope is undeniably astronomy's newest darling. Launched in late 2021 as the successor to the iconic Hubble Space Telescope, this ultra-sensitive space observatory has been churning out fascinating results and spectacular deep-space photos almost continuously.

I recently had the pleasure of attending a lecture in Maastricht about this marvel of engineering, presented by renowned science journalist Govert Schilling. Titled Unbounded Universe: A Journey Through the Cosmos with the James Webb Space Telescope, the presentation took us through the rich history, complex construction, and ingenious design of JWST. Govert showcased a stunning array of impressive images, offering a breathtaking introduction to the mysterious cosmos we all call home.

I was joined by my Helios colleague Walter for the evening. The atmosphere was buzzing because the auditorium was completely packed to capacity, and there was even a waiting list to get in. It is always inspiring to see such a massive turnout of people eager to learn about the wonders of our universe.

At the end of the lecture, I managed to catch up with Govert and take a quick selfie to add to my collection from previous talks, keeping the tradition alive.

It was a fantastic evening filled with awe-inspiring science, incredible visual art from the depths of space, and great camaraderie. A huge thank you to Govert Schilling for another wonderful presentation!

Doppler effect Sol'Ex Sun September 10

 

I made a movie using h-alpha images from September 10th, 2026.

The movie shows the sequence from the photosphere to chromosphere and back with a range of 1 angstrom. The pop up of the filament in the photosphere is due to doppler effect and the filament has a speed of 46km/s.

  

Sun September 10, 2026 - Sol'Ex

No clouds in the morning; later on clouds started to populate the sky. Still issues with Sol'Ex, mainly with the connection with Herschel Wedge and Sol'Ex. After my session was completed, I glued to connection together. 

Total Solar Eclipse August 12, 2026

My pictures of the Solar Eclipse of August 12, 2026 are reworked. I used 3 bracketing images to create a HDR image. Wavelets and HDR done using AstroSurface. CS4 next to stack and final editing.

Solvay Public Lectures - Kip Thorne - Gravitational Waves

 

Two Nobel Laureates will be talking about gravitational waves @Flagey: Kip Thorne and David Gross.

This will be on Sunday October 25th (15h).

Sol'Ex H-alpha, H-beta and HeID3

 

After more then a month, I took the time to capture the Sun using my Sol'Ex.

Seeing was moderate but with some clouds coming over.

The main challenge was the setting of the scope after usage during the total solar Eclipse.

Setting

Sol'Ex on TLAPO80/480 and ASI678MM

Herschel wedge and IR Cut filter

Sx/Sy = 1 and Tilt between 0,5 and 1° (need some more time to adjust)

Software: SharpCap, Inti, AstroSurface, CS4

My Sol'Ex picture of the Sun on the Cover of Magazine "Heelal"

 

WOW! My Sol'Ex picture of the Sun of July 15 is published in magazine "Heelal". How cool is this getting this acknowledgement.

Adapt a Pixel Nancy Grace Roman Space Telescope

 

Claim your pixel on one of the first images from NASA's Nancy Grace Roman Space Telescope! When Roman captures its first images, each pixel will represent a piece of the cosmos never seen before at this resolution. Claim your pixel and be part of this historic moment!

So I did and my unique number is 32307. When posting this message, 286500 pixels are claimed. 

La Palma Telescopes

Last summer I visited the Canary Island, La Palma and nicknamed La Isla Bonita (after the song from Madonna). 

We spend an afternoon around all the telescopes... very impressive and with the clouds below, it was a fantastic view.

Some telescopes: 

- William Herschel

- Isaac Newton

- Gran Telescopia Canaries

- Mercator telescope

- MAGIC & Cherenkov

- DOT or Dutch Open Telescope

- and of course Swedisch 1m Telescope

All of them are located at La Roque de los Muchachos at 2400m above sealevel.
