It has been the third time the Borealis Astronomy Club organized its camp in Alba county, Negrilesii Valley. The area is a treasure for astronomy since it lies in a virtually black spot of the Romanian Light Pollution map. On the other hand, by day it is a pitoresque landscape with tourist attractions like the Detunata cliff and, well, another kind of tourism, the disputed mining area of Rosia Montana.

We were 8-14 people in the camp doing mostly visual observations the main instrument being a 30 cm (12″) newtonian on a dobsonian mount. Among others I myself did almost exclusively astrophotography using a motorized (but unguided) EQ3 mount and an unmodified Canon 1100D enhanced by Magic Lantern and various tele- and wide angle lenses my primary target being the Veil nebula using the Canon EF 200 mm lens at F4 or F4.5.

Here are some of the photos I captured and processed. While the Andromeda and the veil came out quite decent, I am a bit disappointed by the overall quality of the pictures. Maybe I will reprocess the raws some other time.

I would also like to share the light frames with anyone who wants to give them a try (1.zip, 2.zip, 3.zip, though the pictures are not in any particular order, multiple zips due to filesize limit). I will not maintain these files, the links may die after a while: the zip files are located on my raspberry pi so cut it some slack please :)
