    Default IC 59, IC 63 Ghosts of Gamma Cassiopeiae, and The Little Cocoon in Sagitta



    Hello all,

    the emission and reflection nebulae IC 59 and IC 63 make a ghostly arc immediately NE off the bright Gamma Cassiopeiae, Distant Lights - IC 59 / IC 63 , and due to this bright ionizing and illuminating star, these nebulae can be tough for the visual observers with the small telescopes.

    Hence, I have chosen this pair of nebulae for the first light through the recently acquired Leica L 8x (f=32mm, AFOV 45°) eyepiece, which becomes a high contrast and high transmissivity of light companion to the Leica HC Plan S 10x (f=25mm, AFOV 50°).

    The suspected position of these both nebulae framed by other stars has been readily found with the wide field eyepiece (f=25mm, AFOV 70°).

    Having pulled away the bright Gamma Cassiopeiae from the small fields of view of the both Leica eyepieces, a faint arc of ash grey glow with a sharp corner has been first observed through the blue(RGB)CCD filter, which passes both the ionized Hydrogen blue emission lines, and the bluish Rayleigh scattered light.
    And finally, the H-Beta filter has separated the both nebulae, dimming the arc and the reflecting scattered light on the molecular clouds associated with the Hydrogen gas in the nebulae.

    The views through the both Leica eyepieces have been comparable.


    The Little Cocoon is a diffuse emission and reflection nebula Sh2-82 (LBN 29) around a ionizing and illuminating star (B0 spectral class). This nebula form reminds the Cocoon or the Trifid nebulae.

    The nebula is easily found about 2° SSE off the Coathanger Cluster in a “Big Hexagon Asterism”)*, which is nearly 1° across, Distant Lights - Sh2-82
    A wide field capture, showing the dark nebulae around the Little Cocoon is here,
    https://www.spektrum.de/alias/wunder...nebula/1593228

    The nebula became immediately visible as a faint oval of nearly 10 arcminutes through the star hopping f=25mm wide field eyepiece with the H-Beta filter. A brighter view with more contrast has been through the lower magnification Leica eyepieces (f=25mm and 32mm), and the brightness has increased even more through the blue(RGB)CCD filter.

    Even if this nebula has not found its way into the NGC and IC catalogs, and even if it is not included in the popular lists, I would rate it as one of the bright EN RN nebulae, and as one of the best EN RN nebulae on the autumn night skies - at least before we will see the Trifid Nebula rising high enough above the horizon.

    Date and time: 10th and 11th October, 2018, 21:30 – 23:30
    Place: Backyard
    Telescope: 6” F/5 Synta (Sky-Watcher) achromatic refractor
    Eyepieces: Star hopping EP Antares W70 f=25mm
    Leica L 8x (f=32mm) AFOV 45°, Leica HC Plan S 10x (f=25mm) AFOV 50°
    Filters: Astronomik H-Beta, Baader blue(RGB)CCD
    Observing conditions: The Double Cluster, M31, and the Alpha Persei Moving Group visible with unaided eyes

    )* The “Big Hexagon Asterism” is one of my asterisms used for star hopping in the night skies.
    It is not listed.

    Hello JG.,
    Masterpieces of observation again!

    Spooky indeed, those first two.. I have never seen this little Cocoon. I suppose they are not observable in my LP skies? At least Stellarium Web version shows them in all their glory.

    The fact you have spotted them shows great craftmanship! Thanks for reminding us that a six inch instrument and the skills of a Master reveal enough objects for the next 150 years!

    I have noticed that you regularly use a blue (RGB) CCD filter, which passes ionized Hydrogen light, in this case with exitpupils of 6.5mm and 5mm. I must admit that my interest in filters has grown. I wonder if a H Alpha filter could work too visually with the same exitpupil? Or is the blue filter enough? Very interested in your answer.

    Thanks very much for this report!

    Clear skies!

    Hello John,

    our dark adapted vision is blind to the red H-Alpha spectral line (656nm).
    So, all we need are filters passing the OIII doublet (close to 500nm), and the blue Balmer series spectral lines:
    H-Beta 486nm, H-Gamma 434nm, and the H-Delta 410nm.
    The other Balmer spectral lines are in the UV, so they are not visible.
    And this is the reason for the Baader blue(RGB)CCD filter, which passes 400nm up to about 510nm, and blocks the other wavelengths.
    Hence, under some circumstances, the Baader blue(RGB)CCD filter works better than the H-Beta filters,
    as it effectively offers about 15% more light than the single passed line H-Beta filters.

    The Baader blue(RGB)CCD filter is also suitable for the reflection nebulae, when their light is due to the bluish Rayleigh scattering on the molecular clouds.

    Yesterday night, I have had a breathtaking view on the Pleiadas with their nebulae.
    The cone of the Merope Nebula has been no problem.
    Moreover, the space between the stars in the cluster has been dark - besides the nebulae surrounding the brightest stars, and the environments outside the cluster have been lighted due to the Rayleigh scattering on the blown away molecular cloud.

    Many thanks for the comment of you John, and of Mark,

    JG

    Hello Milan,

    as you have better skies, and you have developed very successful observing skills, I bet you can see the Little Cocoon
    without any filter, at least with averted vision. You will try out most of your eyepieces.

    Best,

    JG

    Default Re: IC 59, IC 63 Ghosts of Gamma Cassiopeiae, and The Little Cocoon in Sagitta

    That's an excellent report.
    The ghosts of Cassiopeia are difficult targets to view. I never had any luck with them visually. I did get a very faint image last year.
    I attempted the little cocoon/trifid, also with no luck.
    I only used a wide band light pollution filter. It looks like I may need to invest in a few more filters.
