Good effort Paul, you should take some single exposures of 30 to 60secs unguided with your Star Adventurer reasonably well polar aligned, and using a much longer lens if you have one, say 250- 500mm. This is 30 secs unguided of Eta Carina with my 8" Newt at prime focus [Fl 1000mm]. With such long single exposures you won't get the noise control that stacking provides, so enable in camera long exposure noise reduction, and high ISO noise reduction features, remembering that the camera will take a dark sub of the same duration as your original sub, so the image won't appear on the screen until that process is complete. I apologise for teaching my grandmother to suck eggs as the saying goes if you are already familiar with these features. Have the noise reduction on the strong setting when taking only a single frame.
Actually, Eta Carina would look good at 250mm.
