Here are 86 images of all the galactic NGC nebulae that I know of:

Nebulae in other galaxies (LMC, SMC, etc) and planetary nebulae are not included.
These images were made using

It might give you a guide on what to image.
The scale is the same for most images, 56' x 56'.
Images of large objects are 112' x 112' and small ones 28' x 28'.
