Approximately one week ago, I got email alert from the CalSky service. It predicted that the ISS would pass across the Moon disk at southern Finland, on Sunday morning 18th March 2012. The time for the crossing was 07:13:02 local time, re-checked yesterday - schedule was 07:12:57.
I tried to prepare equiment for taking image sequence of the ISS, with Nikon D200 and C8 OTA. Also found out that memory buffer at D200, fills is pretty quickly - max 5s sequence at 6fps. It would have needed at least 10...15s of buffer, because the passing of ISS would propably (?) change some seconds of the predicted time.
Another problem would been carrying the C8 scope to suitable place, since I do not have a car. On top of the building - there would be high place, but metal fence blocks the visibility. So then, waiting for the next passing of the ISS over moon or sun disk...

Optics Picture of the Day - Fograys
Few days ago I got my image published at Les Cowleys site, you can see it here. Image was taken at Myllykoski, near the city of Kuusamo in February 2011.
That particular place is suitable for photographing fograys, since on many clear winterdays with sunshine - fog rises from the unfrozen river and sun draws it beautiful rays to patchy fog layers.

Imaging laptop, software installation completed
Finally it is done !! All the required software is installed, last one was Nikon Camera Control Pro2. My Lenovo EDGE11 currently looks like this:
There is still some tweaking left for the used software, like defining imaging setup focal lenght, aperture sizes etc. Laptop has to be fitted in the rigid case, Pelican 1450.

Imaging accessories, USB hub ordered...
During last months, I have been preparing my imaging setup (mainly for DS photography, partially for solar system imaging also). I will connect all the equipment to one hub, thati s located in the mount. Then I only have to route one USB cable to the mount from imaging laptop. I have selected a MOXA 407-T industrial USB hub for my purposes, delivery is esimated in two weeks. Short specs are:
wide operating tempetature range, -40 to 85°C
DC power input, 12-40 VDC
7 USB ports
metal casing
inputs ESD protected
The prize of this hub is very high, to be honest. I hope this will be "The Hub", that will last for a lifetime - or even longer than that....

Opinion poll, light pollution in Finland
Light pollution, this is the area of nature conservation, that has been ignored way too long. Day by day, less people are able to see the magnificent wonders of beautiful night sky with thousands of twinkling stars. There is also a risk that light pollution affects to humans natural day / sleep rhythm - especially if bright lights are shining through the night. The affects to nature, like birds, needs more investigating. This problem is getting bigger and bigger. Now it is time to make a difference !
Finland’s environmental administration has introduced opinion poll. There you can share your concern of the light pollution problems. For more details about poll and web feedback form (in Finnish only), use following link here.

Imaging laptop, accessories arrived
On last week, I got packet delivery from UPS, ordered accessories arrived:
So there is now a rigid Pelican 1450 -case for imaging laptop (Lenovo EDGE11). All the stuff is needed to put in (laptop, powersupply, display heater, heater controller, usb / ethernet cables). Case also needs suitable connector panel, so there is many things to solve...
The company (Cameranu.nl), where I ordered the equipment, did not make any effort to protect the Nikon CCP2 software package. In the big box, there was no softening material inside at all !!! The disk case has suffered, from the rough handling (see broken lower right corner of plastic cover). CD -disk seems to be in good condition.
