Welcome to Henk Aling's website. Below are some links that I want to share.

• Hikes : My hiking albums
  • Father-and-son Grand Canyon crossing 2022 : Crossing the Grand Canyon with my son Michael. We went North to South on the North Kaibab trail and the Bright Angel trail. Michael got a heat stroke but fortunately we found a creek where he could cool off. The crossing took 16 hours.
  • Grand Canyon crossing 2024 : This was during the Grand Canyon star party at the Kaibab Lodge. The first night I camped in the forest and left at 4 AM from the North Kaibab trailhead. I finished around 6 PM on the other side, after hiking the Bright Angel trail up. It ends with a few more hikes (Widforss, Uncle Jim, Arizona)
  • Kaibab star party 2025 : Pictures of the Widforss trail that goes around the Transept canyon, a section of the Arizona Trail starting at the Kaibab Plateau trailhead, a picture of the GC lodge with telescopes of the North Rim star party and views of the Bright Angel canyon from the Ken Patrick trail. There are also some views of the beautiful meadow in front of my cabin.
• Astronomy : My astronomy albums
  • Astronomy pictures : My hobby is astrophotography. I have two Losmandy G11 mounts (one standard, the other with OnStep) and an AVX. My cameras are ASI2600MC and ASI2600MM. My telescopes are ES ED127CF, GSO F/4 Newt 12", ES MN152 (Comet Hunter), WO Redcat51. Some wide field pictures were taken with a modified Fujifilm X-a1.
  • Observatory : I built a modest observatory with a view of the Southern skies next to my kitchen area. It is a cheap metal shed with a modified roof that I can slide off and on with counterweights.
  • Artificial star : An analysis of the diffraction and spherical aberration of an artificial star placed at a finite distance.
  • Equatorial platform : A Scilab script with a 3D graphical interface for design and animation of equatorial platforms. The design options allow for Gee and VNS sectors North and South, and a South pivot. The cone apex can be moved above the bearing plane to accommodate a wider center-of-mass range.
• Guitar song recordings : After I developed an injury in my left wrist and was unable to play guitar for two years, I decided that I should get some studio equipment and record some songs. Enjoy it if you can, listening is free of charge and worth every penny!
