After starting this project back on Aug. 2, 2011 and getting the H-alpha and OIII data, we finally had a clear night to get some SII. We were beginning to think it wasn't meant for us to have an HST version of this region because everytime we would try to get out the clouds would roll in. Then to add insult to injury, we discovered that something went wacky with our focus the other night. We think that auto temperature compensation went a little crazy. Thank goodness we were able to salvage the data. So, after nearly a month of waiting, here is the HST version. Cederblad 214 is a large faint emission nebula in the constellation Cepheus the King. It is also referred to as Sharpless 171 (Sh2-171) and is part of a much larger region known as NGC 7822. The small, bright star cluster located just below and right of center is Berkeley 59 (Be59). This complex lies approximately 6,000 light-years from Earth.
