DSLR image of NGC1097 *with* jets 50+ hours

This image comprises more than 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 when compared with the best imagers here on IIS my processing skills are really still at the "intermediate" stage, so 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: http://www.astrobin.com/rawdata/publicdatapools/21/ (Note: requires an Astrobin account to access)

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
