    Hello John,

    at the low magnifications through the richiest field comet hunters, the NGC 2420 looks like an unresolved fuzzy.
    This may be the reason why David Levy has put it on his list

    This evening I tried NGC1788 again. For the third time now.
    The Moon did not bother much, the light of the nearby Maasvlakte of Rotterdam disturbed more, just like the previous times.

    At the place of destination I noticed a star of magnitude 10 and a few minutes later one of magnitude 13. Later on a slightly lighter spot appeared which turned out to be a very faint star. A good deal fainter than 13. Sky Safari Pro gives several stars in that spot, fainter than 13. But a misty object? A slight disturbance in the background-glow? Very doubtful. When I say that I have seen him, I lie. When I say that I have not seen anything, I also lie. In that order of magnitude ...

    Hello John,

    yeah, that's the Fledermaus, the little grey faint bat, difficult to see.
    Ronald Stoyan has made a sketch, maybe this helps.
    Clear skies,

    Hello JG,

    Thanks!,

    In the meantime I have seen the sketches of Ronald Stoyan in the Reiseführer and in Deep Sky Guide. I have been in the right place and have seen the main stars, but I am blind as a bat as the bat is concerned. I will hear him squeak before I will see him, I am afraid

    Sketch of the light pollution. Even an eight inch SCT under more or less the same circumstances over here was not able to reveal some nebulosity. A ten inch Newton was needed to see something.

    Special sketch: NO NGC1788

    Around the two brightest stars the two cores of the nebula should be.

    Hello John,

    don't give up, all you need are better skies.
    Your sketch shows the expected position of the nebula spot on.

    Here is my logbook entry on the NGC1788:
    150mm F/5 25mm blue(RGB): bent oval as described by Ronald Stoyan
    24. Feb 2014 M45, Double Cluster, Beehive with unaided eyes

    Other telescopic nebulae observed on that night through the 6" frac:
    Dzeta Ori Nebula, Running Man Nebula, Horse Head Nebula

    So, if your skies allow you to see the other 3 nebulae as above,
    then you should also see the Fledermaus Schmaus.

    Best,

    JG
