    Default Blue Flash and Fetus nebula



    In this thread J.G. reminded me that NGC 7008, the Fetus planetary nebula in Cygnus, has a somewhat brighter counterpart in Delphinus: NGC 6905, the Blue FLashnebula. Both planetary nebulae. NGC 7008 Fetus-nebula, between Sundown and Moonrise.

    I sketched the Blue Flash in august 2016. Yesterday I revisited the Blue Flash with my 120mm frac. under less ideal circumstances. So this seems to be a good opportunity to show them both.

    -The Blue Flash was sketched in august 2016 during my holiday under Bortle 4 skies. No filter was used, and seemed not really necessary. The instrument was a 140mm Maksutov with 180X magnification. I wished I had used a filter because the positioning is not 100% correct.

    -The Fetus was sketched in september 2018, under Bortle 6-7 skies, a CLS filter was very necessary, magnification 130X in my 120mm refractor.





    Thanks to J.G. for bringing up the idea.

    Hello John,

    this is a very nice comparison of these both planetaries!

    The fact, that in a realtively small area of skies we can easily find and observe even through the samll apertures
    six large planetary nebulae, is amazing:
    The Ring, The Dumbbell, The Blue Flash, The Blinking, The Also Blinking (NGC 7048), and The Fetus,
    and when we add the much smaller but pretty bright Magic Carpet, then we have seven!

    On a side line, when will you start writing a book with your sketches?

    Best,

    JG

    Hi John. Sorry to come in late on here. These are both excellent sketches from you. You really transferred what you observed nicely onto your sketch pad. Thanks for taking the time to put these up on here for us to enjoy John, and the best of wishes for many clear skies.
