ASTRO: NGC 40
While waiting for M76 to get higher I recently imaged NGC 40. I wanted to do
a UHC:R:G:B, but didn't manage to maintain good colours after adding UHC as luminance, so here comes a straight RGB of only 5x5 minutes per channel. One neat feature of NGC 40 is the "overlay" of a red Ha object with a blue (probably OIII) object. Most planetary nebulae will show up blue in the center and probably red in the outer parts. Here we have two complete objects superimposed upon another (don't know if this sentence makes sense, too lazy to check a dictionary). Taken from the middle of Berlin with a 10" Meade ACF at 2060mm focal length (CCDT67 Reducer) on a G11 mount, SXV-H9 camera, 5x5 minutes each for RGB. http://ccd-astronomy.de/temp9/40RGBgut.jpg Stefan |
