There are many places in the space where new stars are born. Reflection nebulae IC4954 (near center) and 4955 (lower left) is one of them. These nebulae surround open cluster Roslund 4. Whole complex is located 6500 light years away and is about 4 million years old. Can be found at the northern border of Vulpecula (Little Fox) constellation.
Roslund 4 consists of about 30 stars, . This cluster is split to two main groups, that are apparently related to the locations of both parts of reflection nebula. Curt Roslund was a Swedish astronomer who discovered seven open clusters spectroscopically. Roslunds clusters are elusive and not obvious objects not listed in other catalogs.
I collected data to this image during two nights with surprisingly good transparency (as for my location). But in the same time the seeing conditions was far from perfect. It is quite often scenario at my location: good transparency comes with bad seeing. Haze and/or high clouds comes with pinpoint stars. Too bad 🙁 Nevertheless I am pretty happy with this image, because I can capture elusive reflection nebulae in a very few nights during year at my location. And this IC4954 and Roslund 4 complex is a rare target for astroimagers.
