Description

This target is a fantastic active nebula with delicate Ha emissions , Herbi-Haro objects, young stars and beautiful delicate blue reflection details. From APOD: "Young suns still lie within dusty NGC 7129, some 3,000 light-years away toward the royal constellation Cepheus. While these stars are at a relatively tender age, only a few million years old, it is likely that our own Sun formed in a similar stellar nursery some five billion years ago. Most noticeable in the sharp image are the lovely bluish dust clouds that reflect the youthful starlight. But the compact, deep red crescent shapes are also markers of energetic, young stellar objects. Known as Herbig-Haro objects, their shape and color is characteristic of glowing hydrogen gas shocked by jets streaming away from newborn stars. Paler, extended filaments of reddish emission mingling with the bluish clouds are caused by dust grains effectively converting the invisible ultraviolet starlight to visible red light through photoluminesence. Ultimately the natal gas and dust in the region will be dispersed, the stars drifting apart as the loose cluster orbits the center of the Galaxy. The processing of this remarkable composite image has revealed the faint red strands of emission at the upper right. They are recently recognized as a likely supernova remnant and are currently being analyzed by Bo Reipurth (Univ. Hawaii) who obtained the image data at the Subaru telescope. At the estimated distance of NGC 7129, this telescopic view spans over 40 light-years."

Steve and I had some vain and foolhardy hope that we might pick up some of the tenuous Ha strands streaming away from the nebula - no chance ;-). Nonetheless the TEC140 has done a fine job.
