I have taken lots of images in the last year. About 20.
This is one I took fairly recently, about 3 weeks ago.
NGC300 is a favourite of mine.
I have CDK17 data for this one I took in the past I may add to it.
AP RHA 305, QHY600m photographic version, PME mount, ASI290 guide camera. Taken at my home observatory in Kurrajong NSW (semi-rural skies).
9 hours 20 minutes all 1x1 binned RHA data plus 11 hours of CDK17/FLI Proline 16803 data for a total of 20 hours and 20 minutes of data.
