We had our new moon weekend curtailed by fog at 1:30am on Friday night but I did manage 3 hours on M83 and I think the result is not too terrible. I hope to add some more data over the next few months but in the meantime...
Higher res version here:

Gear used was my Ceravolo 300 @ 2760mm focal length, Apogee Alta U16M camera and Astro-Physics AP900 mount. 6 x 900 sec Luminance and 3 x 600 sec Red, Green and Blue. A very minimal data set but I was pleased to get anything after the weather we've had since spring.
Only minimal processing in PixInsight. I'll do a better job if I get more data
Cheers,
Rick.
