Description

NGC 7129 is a reflection nebula in a star forming region in the constellation Cepheus at RA 21h 43m 8s and DEC +66d 9m 24s. It lies in the Cepheus Flare in a region of a young star cluster of B-type stars along with several low-mass, pre-sequence stars. The longer pinkish arcs near the lower right and upper left of the main reflection region represent molecular ridges.  The bright, small, curved pink object near the bottom of the reflection region is a Herbig-Haro object (103). There are several more near the top of the reflection region, also representing fast outflows from young stars.  North is up and toward the right. The field is about 35 x 35'. 

Data were taken automatically with CCDAutoPilot4 running Maxim4.62 for camera operation and PinPointPro for plate solving.  The system was off-axis guided using an Astrodon MonsterMOAG and SBIG ST-402 guide camera.  Astrodon Generation 2 LRGB 50mm square filters were used in the Apogee filter wheel. Calibration and initial processing were done in CCDStack and final processing in Photoshop CS3.
