    Hello, this is the blind astrometry solver. Your results are:
    I'm sorry to say that I couldn't solve your system. However there is some good news! Someone should be around soon to solve your image by applying a few tweaks. We'll let you know how that goes.

    Lovely meteor streaks... some are nearly perpendicular to the majority.

    Thanks Lagrangepoint as usual,

    Frames were taken between 1:59 and 4:29am August 12, 2010HST, 11:59 and 14:29 August 12, 2010UTC, and thirty five meteors were recorded in those frames. Perseids were active at the moment, and the radiant was near the upper quarter of the right edge. Many meteors in the frame must belong to the group, though many were not so bright unfortunately. I should have opened up the aperture at F2.8 then.

    Some meteors may be sporadic, though Delta Aquarids were also active then, and the radiant was above the horizon in the south west, upper left outside of the frame. I watched some bright meteors came from the north including the brightest bluish one, and they may belong to Delta Aquarids.

    BTW, I made an action set in Photoshop and automated some processing with it. It was easy and convenient.

    Does anyone remember the episode of "Space 2063" in which Wang was standing after a engine adjustment on the wingtip of the transporter (WW I - Christmas...)?

    Universe is beautiful! And this ones even real. Awesome photo.

    I really need those "Riddick" eyes.

    Its a pity, during the Perseid's it was always heavily raining at my site. Looking forward for the Orionids.
