853 second image

Comet Tuttle is displaying a lawn-sprinkler shape as our vantage point is just right to see it face on, much like a spiral galaxy. It is difficult to see in normal images. The image on the right was derived by taking the difference of two images that were taken a couple of hours apart.

Full Image This impact was very dim for my setup. See the arrow pointing to the faint speck in the cropped image on the left.

Although I'm not sure, this was possibly picked up in four telescopes; two in Huntsville Al, one in Georgia and this one located in Maryland.

I was shooting sucker holes and LunarScan coughed up this event. Both Odd and Even video fields are about the same brightness. It looks sketchy at best and the conditions were really awful. Worth reporting though...
