    Zutopian this is brilliant! Thanks so much for the help!

    Short video of interest. Microlensing and effect of free floating planet. Note effect on local stars as caustic crossing lensing effect develops.

    Hi zutopian. Good suggestion. I included it here as an example of an, admittedly rare, but possible effect that microlensing can produce; altering the appearance of the field as a transitory (even non-repeating) phenomenon. And because I like it:-) You wouldn't necessarily get an Einstein ring becoming apparent (depending on the orientation, mass etc) but you may get an observed "movement" of the bodies affected. I don't know whether or not that would be recordable in a Hubble image, but thought that it might be possible? The time lapse involved in multi layering through different filters that makes asteroids observable could conceivably (I thought) be seen if background stars, or whatever, we're apparently "moving" over time. I had tested the waters with a "? Lensing" post that trevor_allen kindly corrected me on. http://talk.galaxyzoo.org/objects/AGZ0003b27
    I need to understand the significance of the colours better, but don't want to ruin a good fantasy... Sorry discard a plausible theory... too soon.
    Since the issue revolves around the Hubble photometry and/or image processing I thought I'd post it here for Possible Future Discussion. So this seemed a fair repository as a placeholder lest I lost it 😃
    Planethunters are probably all too familiar with my whacky lensing obsession anyway lol:-) but I think I'll post it there as general interest anyway. Thanks again.
