Title: Comet 9P/Tempel 1 dashing through the star field of Sgr - the attempt to bring up the tail
Description:
15min integral L exposure of 9P/Tempel 1 (currently about +14m) quickly passing through the star fields of Sgr near NGC 6717 (Palomar 9) globular cluster - captured using Telescope #1 (ASA-RC D = 1m f/6.8, FLI ProLine 16803) system of ChileScope observatory. The wider field of view for this area is also available under [1].
The composite insert in the lower left corner shows the attempt of bringing up the tail of the comet by running the difference between the first frame and the last frame (frames 1 and 5) in the sequence and suppressing all non-diffuse objects on those (note the 1.5x magnification applied with respect to the source images made for convenience of viewing).
