Welcome to Henk Aling's website. Below are some links that I want to share.
- 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.
- 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.
- One-day Grand Canyon crossing in 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)
- 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!
