no worries Glen, I saw your astrobin version was down. cleaning helps but also flats will get rid of the strong gradient/haze throughout the whole image - not just the dust bunnies - which I artificially attempted to remove in the second image. my HH from last year looks the same as yours because I didn't take flats back then.
I recommend twilight flats - as you are using a DSLR they are actually quite easy to take - in terms of getting the exposure right. when at dusk find an even patch of sky and select the Av mode on the canon camera and start snapping away - no focus required. make sure no stars are evident. this page will help too

So looking forward to seeing more
Cheers
