    You are not limited to twilight if you don't take altitudes.
    In a dark starry night many more stars are available than the
    usual lunar stars.

    This is indeed a problem. I had to use my intermediate filter
    to reduce the moon's glare today.
    Still for a half of a month, osculations by the dark edge of the
    moon will be available.

    I mean when the moon is growing.

    Not in the online version I use.
    When I'll make my own lunars spreadsheet I will
    definitely try it.
    The Frank Reed calculator which I use does not allow many
    stars. Besides it is down mow:-)
    Just at the time when I came with my new series of the lunars.

    Alex.
