My Astronomical & Blog statistics

My astronomical and blog statistics.

- Same blogposts as the last two years
- Increase visits and now above 240.000 visits
- My project "Herschel 400" is not progressing
- A total of 16 observation nights, which much better then last year and comparable with 2023. The focus is on a couple of objects and long exposure images made over more days; eg. Comet C/2025 A6 Lemmon and Bernard's Loop.

Bernard's Loop Sh2-276

After a first session on X-mas day and a failed second session, a third session was completed on December 28.
This third session was a combination of H-alpha and Optolong L-Pro; all of them 300s exposure time.
Using APP, all images are stacked, resulting in a total integration time of 4hours 25minutes.




Bernard's Loop and Sh2-264, Lambda Orionis Ring or Angelfish Nebula is good visible. I'm still doubting on the quality of the images. Hopefully I can add one more session to get up to 6h total integration time. 

Sun on December 28

The Sun on December 28, 2025. Interesting is the Magnesium Mg I B2 line with a small prominence.

Setting: Sol'Ex by James R, with 2nd Gen slit and Herschel Wedge
Software: SharpCap, Inti, JSol'Ex, CS4, DeNoise AI
Tilt < 0,2° Sx/Sy 1,1









 

Book "Gek op Natuurkunde"

Walter Lewin is a famous physicist and teacher, best known for his inspiring lectures on physics at MIT. He has a unique way of explaining complex ideas using clear demonstrations and a lot of enthusiasm. His passion for science has motivated millions of students around the world.

In his book Crazy About Physics, Walter Lewin shares his life story and his deep love for physics. The book combines personal experiences with explanations of physical phenomena, making science feel exciting and accessible. Through stories, experiments, and reflections, Lewin shows that physics is not just about formulas, but about curiosity, wonder, and understanding the universe.

You should buy Crazy About Physics because it makes physics exciting and easy to understand through real-life examples, stories, and experiments. Walter Lewin’s passion and engaging teaching style can inspire your curiosity and help you see physics as something fascinating rather than difficult.

Bernard's Loop Sh2-276

Bernard's Loop is identified as Sh2-276. Sh2 is the abrevation of Sharpless, a catalog of 313 H II regions (emission nebulae) published in 1959 by US astronomer Stewart Sharpless. Sh2 is referred to the second and final catalog. Number 276 refers to a H II object, in this case Bernard's Loop.
The image below shows Sh2-276 and Sh2-264, Lambda Orionis Ring or Angelfish Nebula.

Setting: 



Nikkor 24-200mm with ASI2600MC and H-Alpha filter
Exposure: 29x120, 19x180, 4x300 or  total integration time of 2h15min
Software: SharpCap, APP, DeNoise AI, CS4

1) Attending Space Weather training at STCE
2) Aurora during our holliday in Iceland
3) My new Sol'Ex by James R with 2nd Gen slit, capturing E Corona & JASON2025
4) Red rainbow with more then 4700 likes, 245 remarks and 52 times shared
5) My first long exposure of 7h capturing M51
6) M31 with asteroid Eros and learning ASTAP
7) Sunspot AR4048
8) Interstellar Comet 3I/Altas
9) Planet Jupiter, Mars and Saturn
10) Comet C/2025 A6
11) Wide field of Mercury, Venus, Jupiter and the Moon
