afesan Posted June 17, 2013 Report Share Posted June 17, 2013 This area is a relatively unknow area of Cygnus ..and maybe this could be one of the first amateur image .. Into the image 3 Herbig-Haro targets can be seen ..forming into the dusty-gas clouds LDN 1002 and LDN 1003. Also an RNO object (RNO 127) can be seen. As Wikipedia: Herbig–Haro objects (HH) are small patches of nebulosity associated with newly born stars, and are formed when narrow jets of gas ejected by young stars collide with clouds of gas and dust nearby at speeds of several hundred kilometres per second. Herbig–Haro objects are ubiquitous in star-forming regions, and several are often seen around a single star, aligned with its rotational axis. HH objects are transient phenomena, lasting not more than a few thousand years. They can evolve visibly over quite short astronomical timescales as they move rapidly away from their parent star into the gas clouds of interstellar space (the interstellar medium or ISM). Hubble Space Telescope observations have revealed the complex evolution of HH objects over the period of a few years, as parts of the nebula fade while others brighten as they collide with clumpy material of the interstellar medium. The objects were first observed in the late 19th century by Sherburne Wesley Burnham, but were not recognised as being a distinct type of emission nebula until the 1940s. The first astronomers to study them in detail were George Herbig and Guillermo Haro, after whom they have been named. Herbig and Haro were working independently on studies of star formation when they first analysed the objects, and recognised that they were a by-product of the star formation process. Here are two Astronomy articles citing the area..Some images into the articles can identify the targets: http://adsabs.harvard.edu/full/1997IAUS..182P..91D http://www.aanda.org/articles/aa/full/2003/47/aa3826/aa3826.html Initially I invested 5 hours in Luminance..but finally decided to collect 4 extra hours in order to avoid noise reduction tools and try to maintain the "dusty" aspect of the area. Star changing colour is also visible.Some spectral lines are aborbed by dust-gas of dark clouds.. so stars are more and more yellow-red as more and more deeper are into the dusty cloud. Also some carbon stars type can be identified.. Link to image gallery : (last one): http://afesan.es/Deepspace/ Thanks for looking. I hope this summer weather could be better than before. This speing has been one of the worst can remember Link to comment Share on other sites More sharing options...

I always like those dark areas...These are between my preferred targets. BR¡¡ Antonio Edited June 18, 2013 by afesan Link to comment Share on other sites More sharing options...
