  4. BSF32 .. a mistaken "planetary",

    in Deepsky

    Posted · Edited by afesan

    A small reflection nebula inside a dark nebula surrounded by dust.Named GN 03.47.9 and also BSF32 (Blitz,Fich,Stark catalogue) was somehow mistaken for a planetary nebula.(PK 149-1.1)
     
    The whole area is inmersed into a big reflection nebulosity and ionized HII, spreading the star lights into haloes,and the background dust muddying completely the image..
    A very weak region. I had to invest a lot of hours just to show some minimal colours and details..Seeing and a  high humidity  along some weeks wasn´t too cooperative,so I had to discard a lot of subframes.
    Anyway, I hope this image encourage other astrophotographers to look far away other than topic/typical targets..
     
    As usual:
    More than 110 subframes x10 minutes each one, unguided and automatically acquired with Sequence-Beta , ASA DDM85 mount and ASA N12 astrograph.

    Antonio,

     

    now you got me curious :) Actually, we are here searching for a place to host a Veloce 200RH in Spain, and we found a nice place which would be, well, not really in your corner but further South.

     

    Cheers

    Lukas, I live in north of Spain...but my observatory is remote-robotic and it´s further south... :rolleyes: .. In the area of " Extremadura"...Southwest of Spain.. Maybe I´m wrong... but could it be "e-Eye" hosting site ??... 

    Cheers

    Antonio

    TGU H774 P19,vdB 2,HBC 326,HBC 328, (Cassiopeia)

     

     
     
    A very rare and interesting zone,close to the border Cassiopeia-Cepheus and some degrees apart from the well-known NGC 7822 nebula. This area is  dominated by the dark nebula TGU H774 P19, breaking the background  (* Tokyo Gakugei University Catalog) and the deep blue vdB 2 reflection nebula. Plenty of interstellar matter,patches of grey and brown dust all around, blurring light of stars and the whole image, even crossing the dark TGU nebula in  lanes.
    Close to the center of image, blue star Tycho 4026:499 is the emission star HBC 328, with a dusty red lane.
    The orange K2 spectral type HIP 1200 star dominates the bottom area and in the upper left corner, over vdB 2, the variable type Orion stars, GCVS V0511 Cass and GCVS V0510 Cass (also emision star HBC 326, Herbig-Bell catalogue, with a red dim nebulosity ) are distinctive.HIP 1021 star has a faint blue nebulosity around.There are also numerous radiosources in the area.(X-ray)

  16. NS2 (aka Magakian 13, DG4, GN 00.42.0 and so on...)

    Confusion about this nebula. Different catalogs and different criteria about it´s nature. Close to the well know "Pacman" (and surely this is the reason which "eclipsed " and ignored NS2 to astrophotographers).. it´s a rare imaged area.by Bernhard Hubl and Rick Johnson , imaged it in the past and I tried to show the dusty enviroment and galaxies showing here and there..

    A heavy light trace cross the image in diagonal.This is the result of the close 2.21 magnitude star Alpha Cassiopeia (Shedar)..No way to avoid it ..

    More resolution (2400x1800) and more detailed information

    The image was acquired with Autoslew, Sequence, MaximDL and all 8 minutes subframes ( about 130x 8 minutes subframes  L+R+G+B ) unguided.

    Thanks for looking

    Clear skies
