  • Build your own GPS tool -- update 2015/09/24 & 2019/02/12

    - 12 Feb 2019
    "Build your own" in this case doesn't mean soldering and writing thousands of line of code. Instead I take advantage of available HW & SW and combine them and hopefully end up with a better (and lower-cost) solution than the off-the-shelf items. This is an ongoing adventure -- come back to see the progress ...

  • So you want to -- match a photo and a sky chart

    - 23 Jan 2015
    Plate-solving is useful -- especially when you use it to correct a telescope's position in real-time . You also can feed the solver an existing photo and manually read the results but using the output can be cumbersome. Manual copy & paste coordinates of input fields of tools like Stellarium helps, but that approach isn't very user friendly. Here's a different take on this -- solve the image and instantly get the sky map of that region. Again, this is using mostly freeeware tools.

  • So you want to -- prepare for an astronomy shoot (Part #3 WHEN)

    - 16 Feb 2014
    PLANNING is in my opinion one of the best ingredients to any successful venture, astrophotography & otherwise. And in another article, I wrote about the WHERE / LOCATION. The right timing of WHEN also is important If I have to explain to you WHY stargazing is great, you're at the wrong page SCOUTING WHERE to shoot is one important step : /stargazer95050/657919 DECIDING WHAT objects to photograph : /stargazer95050/704191 PLANNING WHEN to shoot is another : /stargazer95050/659063 DECIDING WHAT equipment suits the task best : PRACTICE HOW to shoot is just as important : /stargazer95050/657921 POST-PROCESSING of the captured results :

  • So you want to -- photograph the ISS in front of the Sun or Moon

    - 20 Dec 2013
    [UPDATE 2013/12/20] Predicting the position of the Sun & Moon isn't all that difficult with a bevy of apps & websites to help you. Predicting satellite positions, incl ISS, is more specialized. Several tools of the SOFTWARE TOOLCHEST come in handy and I will have to add some new ones for this task. Once you know WHEN & WHERE it will happen, the next task is to figure out HOW. Especially when you aim to shoot a transit in front of the Sun, extra precaution is needed.
