    Ced 51, B30,B31, HH 179, HH244 ( Orion)

     

    Cederblad 51 is a part of the large Sh2-264 nebula, the "Orion's head".Red colour shows the large H-alpha emission nebula (GN 05.30.0), blue the reflection nebulae ( Ced 51) and brown,the dust nebulae (dark nebulae such as: LDN1582,LDN 1584,Barnard  31,Barnard 30..) .Also Herbig-Haro targets such as  HH 179 and HH 244 can be guess between dust.

    Thanks for looking..

    VdB 81, NGC 2254 (Monoceros)

     

    VdB 81 (also catalogued as IC 448, is a reflection nebula in the constellation of Monoceros. Situated between NCC 2261 (Cone nebula) and NGC 2237 (Rosette nebula), It`s illuminated by the 4.47 mag, A0Ib spectral class star 13 Monocerotis (HD 46300).It´s like a blue ink drop expanding as waves between stars: Upper left side of image,you can see the the open cluster NGC 2254 Background showns filamentary emission nebulosity belonging to the Monoceros Loop supernova remnant.*

  18. Barnards 202,203,204, vdB 13, Bernes 63 and lots of Herbig-Haro objects

    The blue reflective nebula vdB 13 is illuminated by the blue star HIP 15984, spectral type B8. Under vdB 13 is the dark nebula Barnard 203. Inside Barnard 203 is another reflection nebula: RNO 14, which shows a reddish-brown colour, located at the edge of Aries-Taurus.
     
    In the left central part, with an intense yellowish tone we see Bernes 63 and several Herbig-Haro objects.
    In the lower central part of the image, the dark cloud Barnard 204 appears, with the Herbig-Haro 422 as a flame in the centre.Some small galaxies appear as a backdrop to the reddish dust.
     
     
    This part of the sky contains a lot of dust nebulae, as well as some exotic objects known as Herbig-Haro Objects (HH), and RNO objects. HH objects are formed when jets of gas ejected by young stars collide with clouds of gas and dust in the vicinity at speeds of several hundred miles per second. you can see more than a dozen of these Herbig-Haro objects in various parts of the image such as reddish-wine objects or shadows.

    LBN 762,PGC 11152,PGC 11410 (Aries)

     

    LBN 762 / MBM 13 : This nice field is located in Aries. 
    This association of gas and dust are early stellar nurseries and newborn stars.Recent studies based in PS1 photometry (April,2014) suggest this molecular cloud is about 191 parsecs away ( Astrophysycal journal, Vol 786,Number 1. E.F.Schlaly et al). 
     
    The structure of LBN 762 is amazing and one must imagine what incredible kind of forces are capable to create such intrincate shapes. 
    Larger galaxies visible in the image are PGC11152 at the right side and PGC11410 at upper left.
    Many other little background galaxies are visible even through the semi-translucid  gas clouds.
