Pentax K5 Rosette
Ngc 2237, Rosette Nebula is a very difficult catch : it's mainly emitting H-alpha rays blocked by Cameras' IR-cut Filter. Plus, it's only visible during Winters' nights with clouds, rain, wind, storms... I shot +/-1 hundred of long exposures. Of which 69 raw files I kept. Of which 8 only that I was able to stack together, just this afternoon, finally ! 8 long exposures of 16 min. through an UHCS Filter :,118675.msg3999601.html#msg3999601,118675.msg8092266.html#msg8092266
