NGC 1097 nearly 50 hours of data taken by Richard Muhlack. Many thanks to Richard for posting this data publicly to be processed. I deeply enjoyed having such amazing data to work with - almost no noise reduction required. (Mainly ATW transform in Pixinsight 1.8 at the linear stage was about all that was required).
Its a great dataset to practice your processing skills!!!
Info from Richard's posting:
Over 50 hours of DSLR image data of NGC1097, captured over 12 nights from my home observatory in South Australia. The FITS file here is the linear image after calibration and stacking.
I have been able to reveal three of the four optical jets (possibly a first for a DSLR image of this target...?), however my processing skills are intermediate rather than advanced and so I am curious to see if those more experienced can reveal more. My processed version can be found here:
