Now the colour version. During the "Perseid night" I had a lot of luck (and maybe also a kind of skilled serendipity). Tons of luck indead that the meteor is captured in both systems (regarding the 10 sec+ CCD downloading time which is an effective exposure pause). Through the middle of a relatively tiny sky area (FOV 7. 2 x 10. 8 °) I could capture this meteor (which is, however, no Perseid but probably a late Delta-Aquariid) crossing Andromeda Galaxy and with multiple outbursts.
Technique: parallel exposure with two imaging systems:
(1) Canon 200mm/F1.8 (open), SX-36, L-pro filter, 240 sec exposure time,
(2) Canon 200mm/F1.8 (open), Sony A7s (CentralDS modded), ISO 3200, IDAS-V4 filter, 90 sec
both on EQ8 mount unguided.
Final image processed with 32 subframes from each system for the galaxy and the stars resulting in a L-RGB image.
