blackhaz napsal: Thank you for your comments, gentlemen!
Here in Ukraine there are lots of good observational places, although my eye myopia does not allow me to detect the limiting magnitude preciesly enough, thus I've ordered an SQM to measure the sky.
Very good idea. I have one and it's really magic box

which allow to exactly estimate sky darkness.
I have 21.15 in my backyard located at western Slovakia

Not bad value 60km from capital city of Slovakia ;)
I think your future measurements will be bellow 21.6 8) I am very curious to your future measurements.
At eastern Slovakia (15km from Ukraine borders) we have very good conditions (21.3-21.5) at Kolonica observatory.
There is the darkest place at Slovakia near borders with your country.
Here in Dniepropetrovsk, there's a place called Balovka where I have my container. It's pretty dark and I am happy with it, however certainly there's an LP on the horizon coming from nearby Dniepropetrovsk and Dnieprodzerzhinsk. People who live in our capital - Kiev - are often going out to observe at Pilipovichi. There's where an old national comet searching station is located and the skies have to be pretty dark there. So far I haven't heard Kyiv people going elsewhere. In Crimea peninsula, there are loads of places such as Nauchny village where Crimean Astrophysical Observatory (KrAO) is located - one of the largest observatories in Europe (if I can call Ukraine a Europe ;D). There's an annual festival in Crimea called "Southern Nights". In 2005 it took place in two locations - first RT-22 - the largest radio-telescope site in Simeiz and then the KrAO. A very interesting photo report is available at http://www.astroclub.kiev.ua/forum/index.php?topic=141.0
There's on page 2 is the photo-review of all the telescopes installed in KrAO. The astroclimate should be very good there although I haven't had a chance to visit that place yet - maybe this year. The one can book an individual excursion or just live nearby the KrAO in the tents (that's allowed) to observe with his own equipment.
Is is really interesting forum (your link). Nice people and starparty 8)
I believe there should be an extremely good skies in Carpathian mountains as well as I see no big cities or other LP sources nearby. I do not have the link of the LP map but will try to find something.
:)
We plan some trip to eastern Poland (again near to border with Ukraine

). Maybe next year, because after month we are going to astro trip to La Palma at Canary Islands (to meet with unpolluted pristine sky). It will be first time in my life, when I see truly dark sky.
