The amazing Rosette nebula! I just love imaging the Rosette. I have recently increased from 2 to 3 minute subs and now using the L-Ultimate, definitely makes the OIII pop compared to the ZWO dual band filter.
This was taken over 2 nights, pretty happy with the result. Used the HaOIII script in Siril to process.
