Garmin forerunner 305 Print
Wednesday, 24 October 2007

ImageThe garmin forerunner 305 is a perfect companion to do your lonely running exercises: It has a very accurate GPS and compared to the older 301 model it is a lot smaller, just a bit more fat than an average full-featured digital watch.

I used it to do one of my favourite training run of exactly 5.4km (which I now know thanks to the 305). It can also measure my heartbeat by wirelessly connecting to a belt around your chest.

The windows software package can project your course and that's where the -until now- one minus point is: it projects some highways but as you can see in the picture, the highway is a bit too much to the right as I did not go under the Dutch A2 but just walked in parallel with it. 

One of the nicest things in here (and as I only used it once I did not yet test it) is that you can run against yourself: you can give up your previous run and it will project on the watch where you ran the last time.

So who says that running is no fun?

Image Ok, this is the final moon I'm going to show you for now. Also made on the same day, but with -again- different settings. I think it's a bit less than the one before. Of couse, you can also see the low-res version of it on this website.

Another moon picture Print
Sunday, 15 April 2007

ImageOk, another moon picture (made on the same day) but with slightly different settings.

It could very well that this picture has been made with the oculair (20mm I thinl) in front of the camera (the previous one probably had the camera directly onto the telescope without enlargement oculair)

More moons Print
Saturday, 14 April 2007

ImageFinding the right settings for your camera can be quite hard. Luckily we have the well-known EXIF information. Unfortunately -to my complete surprise- I could not view this with gimp or any other quite standard tool in my Gnome environment. So I found a small article on using the tool jhead at http://www.linux-magazine.com/issue/36/EXIF.pdf

This moon has been made with the following settings (I removed some of the verbose or obvious fields). More pictures will follow...

My first moon Print
Thursday, 12 April 2007

ImageOk, so I got my telescope. All left to do is connect the Canon EOS 350D to it. What do you need? Well, first you need a T-ring specifically for your camera-type, then you need a universal camera adapter

So, when you have, just connect it, aim for the moon and -click-!  Hmm, did I forget something ? ....
