Over 50 hours of DSLR image data of NGC1097, captured over 12 nights from my home observatory in South Australia.

I have been able to reveal three of the four optical jets (possibly a first for a DSLR image of this target...?), however as my processing skills are intermediate rather than advanced I am curious to see if those more experienced can reveal more. The stacked linear fits file is available from the Astrobin Public Data Pool here:

Telescope: Vixen VC200L with f6.4 reducer

Camera: DIY modded Canon 1000D with regulated peltier cooling @ 10C

Guiding: Lacerta OAG with QHY5L-II

Mount: Skywatcher NEQ6

Exposure details: 305 x 10mins @ ISO1600

Pre-processing: Pixinsight 1.8, calibration with master dark (50 frames) superbias (200 frames) and flats collected after each imaging session (50 frames per day). ImageIntegration: Average Combination, Noise evaluation, k-sigma/biweight scale estimator, Linear Fit clipping rejection
