Here are two test images with the ALccd5 Monochrome camera with the planetary nebulae M57 and M27. It is just a test. Imaging works, but a special deepsky camera would make more sense. M57 was visible already on a single exposure of 2sec.
M57
Stellarvue Nighthawk with ALccd5 Camera.
50*10sec exposure with dark frame (10*10s) subtraction.
The central star (ca 15 mag) is just visible.
M27
Stellarvue Nighthawk with ALccd5 Camera.
50*10sec exposure with dark frame subtraction. Remarkable is the differnce in size.
