OBJECT DESCRIPTION AND IMAGE SESSION

 

It is a large but readily apparent pipe shaped dust lane that obscures the Milky Way star clouds behind it. Clearly visible to the naked eye under clear dark skies, but it is best viewed with binoculars.

 

In a pipe shaped form, this fantastic object covers an area of more than 7 degrees. The only way to capture it all was using the small but quite effective Zenit lens. Blue and Green channels where spoiled by the due, hence the image in colour was impossible to process. The definition of this lens is outstanding and allowed to increase the image almos15% of its original size
