Tonight I went a full hour's worth on one area. Moon is up so used narrowband imaging, 7nm Ha filter
The 300mm Flourite lens from Bert was used, @f2.8
Sensor temp 2 degrees. A single dark, flat and offset was used.
Area is near Eta Carina
4x15 minutes hand guided

The combination of the Flourite lens , cooled sensor and narrowband Baader 7Nm Ha filter makes a mockery of any moonlight present
