Underwhelming Astrophotography

Some nights I can take 200 photos and not salvage a single one. This is one of those nights. I took these shots with a Nikon D5100 DSLR hooked to a Celestron 6" refractor. Click on any of these pics to embignify.
                                            .

Above is NGC 253, a spiral galaxy in the constellation Sculptor. 137 second exposure with an ISO of 1600. I didn't have my autoguider hooked up, so even though I had an excellent alignment, you can still see star trails. I'll get a decent pic of this bad boy yet.
                                            .

This is M76, a bluish planetary nebula in Perseus. 30 seconds at ISO 3200. It's faint and tiny, but if you squint just right, it's in the center.
                                            .


This is the wispy Veil Nebula in Cygnus, which you can hardly see in this picture, even with some editing to bring it up better. 184 seconds at 1600 ISO. The bright star is good old #52. It doesn't have a pretty name.

















This is Mrs. UC's shot of the Veil Nebula. Taken with a Nikon D300 and an f2.8 200mm lens, 61 seconds at ISO 800. You really have to squint. It's a tad left of center.
