Comet 12P/Pons-Brooks in Big Bend (Texas)

My Helios colleague Lieven asked my why comet 12P/Pons-Brooks wasn't selected in my 2024 Highlights. My answer was that I don't have good pictures of the Comet. But then I realised that I tried to image the Comet when I was in Big Bend (Texas) a couple of days after the Solar Eclipse of April 8th, 2024. With the support from Stellarium I good trace the Comet on my images, including Uranus.

Reworked Milky Way Big Bend

I reworked my images of the Milky Way taken in National Park and Dark Park "Big Bend" in Texas (US). This is a real Bortle 1 location. 
Setting: Nikon D7500 on Sky Adventurer 2i
Lights : 44x60s
Editing: APP Stacking and Mosaic on Stars; APP Stacking and Mosaic no Stars, Light Pollution filter, Combining using CS4

Installation of new 7micron slit in Sol'Ex

I installed a new slit (second generation) in my Sol'Ex Pro version. This slit has two positions, 7 and 10micron.The 7 micron position was used. The slit support was 3D printed by a Johan (Helios colleague) and all fit well. Some advantages using the new 7 micron slit results in increasing

  • the resolving power R of the SOl'Ex from 36.000 to 46.000, an increase of 27%  (using ZWO678MM camera)
  • the spectral resolution from 0,18 to 0,14 angstrom for H-alpha; an increase of 22%

The "height" of the slit is now 6mm (before 4,5mm) which makes it possible to image the Sundisk using both my TLAPO80/480 f/6 with ZWO678MM camera.

All information of the second generation slit can be found in the following document from Christian Buil (https://buil.astrosurf.com/starex/slit_solex_gen2.pdf)

Chart of Nuclides

I used to have a chart of Nuclides but can't find it any more :(
On line some interesting links to nuclides websites:


To buy a chart of nuclides, choose the one from Karlsruhe Nuclide Chart via https://nuklid.shop/

At the Tabloo Expoo a Nuclide chart was build in "glass" cubes with additional LED lights.  The X-Y axes are number of Protons and Neutrons, the vertical axe is Energy. The lower, the cubes, the more stable the isotope is. The lowest of all is iron - Fe.





Visiting Tabloo Dessel

Together with Helios Astronomy Club I visited Tabloo Expoo in Dessel (B). Tabloo is the brand-new visitor and meeting centre in Dessel about radioactivity, the management of radioactive waste and research into nuclear applications.

Astronomical Highlights 2024

Again an interesting astronomical year "2024" with some amazing "wow" moments and again great learnings. At home clouds and rain had an impact on my deepsky imaging. But still ...I had to limit the list but these are my astronomical highlights:

#1 Amazing Northern Light show above my home, first time ever 
#2 Sol'Ex presentations, Sol'Ex images and attending ROS in Serbannes
#3 Huge sunspot 3664 which was also published in STCE magazine
#4 Houston Space Center 
#5 Imaging Milky Way in Big Bend Dark Park (bortle 1) 
#6 Visiting Gravitational Wave Centrum LIGO @Livingstone
#7 Occultation of Saturn by Moon
#8 Comet C/2023 A3 Tsushinshan-Atlas
#9 Noctilucent Clouds
#10 Halo's around Sun and Moon
#11 Nightscape Venus and Mercury
#12 Solar Eclips Kerrville-Texas April 8, 2024
#13 Reworked image of Solar Eclipse August 21, 2017 using Larson-Sekanina filter

Horsehead and Flame Nebula reworked using Starnet++




I followed a lecture on postprocessing of deepsky images by Astronomy club Altair (Sint-Truiden). The learning I took away was to remove the stars and edit both the nebula and star image seperate. Once completed combine both images again.

I used starnet++ to remove the stars and editing was done using CS4 and DeNoise AI. The result is better as my stars aren't that big any more compared with the nebula.

Sol'Ex and Doppler Image of the Sun

Finaly some sun! It was only in the morning and with high clouds. I could record a couple scan using my Sol'Ex pro. Setting is not yet 100% due to my new camera. In order to get this back to 100% I need more "sun" time.
The image taken was during an outburst C2.9 in AR3928 with huge prominences. 

Setting: Sol'Ex Pro with TLAPO60/360 and Herschel Wedge
Camera  ASI678MM 
Software: SharpCap 4, Inti, JSolex

I managed to get the X/Y as the tilt close to 1.

Lecture Prof. Frank Verstraete and CĂ©line Broeckaert

Selfie with Prof Frank Verstraete and writer CĂ©line Broeckaert

Together with Helios members Walter and Henk, I attented a lecture by Prof Frank Verstraete and writer CĂ©line Broeckaert. The title of the lecture was the same one as the title of their book "Waarom niemand kwantum begrijpt en iedereen er toch iets over moet weten" (Why No One Understands Quantum and Yet Everyone Needs to Know Something About It). 
The lecture gives an overview of quantum physics by talking about Planck, Einstein, Heisenberg, Schrodinger, de Broglie, Feynman, ... and for me a new name Emmy Noether (see link to wikipedia)
Beside the famous names following concepts were talked: 
  • wave-particle duality
  • superposition
  • quantum entanglement
  • quantum uncertainty
  • quantum interference
  • qauntum spin
  • quantum computing
  • and sysmmetry
As a conclusion, a very well presented lecture with a brief historical overview and good real life examples of quantum physics. After the lecture, by a drink, we kept on discussing, even with the professor.



Bibliography
Frank Verstraete (51) studied civil engineering at KU Leuven and later physics at Ghent University. After a PhD in Leuven, he moved to the Max Planck Institute for Quantum Optics in Munich and Caltech in California. In 2006, he became a professor at the University of Vienna. He built up his own research group at Ghent University. Since 2022, he has been the Leigh Trapnell Chair of Quantum Physics at the University of Cambridge. Verstraete gained fame with the development of a language that allows many-particle problems in quantum physics to be described. For this work, he received the Francqui Prize in 2018, also known as the Belgian Nobel Prize. CĂ©line Broeckaert (43) studied theatre directing at the Ritcs and language and literature at the Vrije Universiteit Brussel and in Bologna. She taught Dutch to non-native speakers and worked for many years at Theater Antigone and Muziektheater LOD. Since 2015 she has been an impact producer for documentaries.
