I received my SV405CC yesterday(June 7) and was able to pair it with my 420 F6 refractor to give it some first light. While the sky was covered in clouds for most of the day and night there was a little gap right before sunset that allowed me to take a quick capture of the moon.
I used SharpCap for capturing (nearly had a framerate of 20 FPS, with a ROI of 2822x2822 and thermal cooling set to -5°C) and processed the image in Siril by using 'sum stacking' of the best 200 pictures of 2000 frames. I lowered the saturation a little bit in Photoshop and cropped the image.

There was a small window of clear skies last night(June 12) and I took the chance to test the SV405CC at -5°C for a total of 90 1-minute exposures on the North America Nebula. Gain was set to 25, black level at 0 and capturing was done using SharpCap.

Here at 51° North, there is no astronomical darkness at this time of the year, so the night sky is always covered in a bit of dim sunlight. I didn't use a filter to capture the nebulosity, the only filter in the optical path was a UV/IR blocker to keep my 70 mm F/6 ED scope from fringing too much.

I captured darks/flats/dark flats (Paul Capino inspired me with his dark flats for his beautiful shot of the Lagoon Nebula) and I used Siril for stacking and processing.

I love the full-well capacity of the SV405CC, as you can see many of the stars in the picture didn't oversaturate and kept their color very well. I'll reshoot the North America Nebula later in the year when it goes up high in the sky during longer and darker nights, but for now I'm pretty pleased with how it turned out with so little effort using this camera.
