OK, here's the third and final couple of pics, the target was M27 (aka The Dumbbell Nebula, NGC6853), a planetary nebula in the constellation of Vulpecula. Again, you get one version with the diffraction spikes and another without. Click 'em for more bigness:
M27 (NGC6853) as processed.
Subs: 22 light @ 120s, 22 dark @ 120s and 20 flat @ 2s, all ISO200.
D50 and MPCC on the C8N, guided with PHD.
As previous but with added spikes.
That's yer lot.
OK, here's the second couple of pics, the target was M29 (aka NGC6913), an open cluster in the constellation of Cygnus. You get one version with the diffraction spikes and another without. Click 'em for more bigness:
M29 (NGC6913) as processed.
Subs: 41 light @ 60s, 41 dark @ 60s and 20 flat @ 2s, all ISO200.
D50 and MPCC on the C8N, guided with PHD.
As previous but with added spikes.
There's even more...
I managed to escape from the house last night and took refuge in my obsy. The skies weren't particularly clear, mainly due to the pending moon-rise, and the seeing was only middling, but I managed to get some dSLR pics of some Messier objects. For the first time I took some flat-frames as well as the customary lights and darks, it wasn't the hassle that I thought it would be, mainly due to me thinking laterally and adapting the "white tee-shirt method" by using a white microfibre cloth over the end of the scope.
The results are worth the extra effort, I reckon - there's less hassle trying to get Photoshop to correct the vignetting inherent in images of this kind. I'll probably knock-together some sort of white-screen contraption for the end of the scope now that I've got a better idea of what works.
Here's the first couple of pics, the target was M13 (aka The Hercules Globular Cluster, NGC6205) and it looks like I've managed to catch the faint smudge of NGC6207 near the top edge of the uncropped version:
M13 (The Hercules Globular Cluster, NGC2605) in the centre, NGC6207 to the upper-left(ish).
Subs: 50 light @ 60s, 50 dark @ 60s and 20 flat @ 2s, all ISO200.

In less than a week I've gained four feet and lost eight and a half Pounds...
The skies on Saturday evening were very clear but after the high temperatures of the day the seeing was only middling. I managed to get some dSLR pics of open cluster M29 and of globular cluster M56, these will need some careful processing for which I've yet to find the time. I did get plenty of good views and camera footage of some lunar features, and I've had time to do some preliminary processing of them, the resulting images are as follows (mouseover for the occasional annotated versions):
Gambart (15 miles dia.), the Fra Mauro Highlands and the Apollo 14 landing site
Plato (61 miles dia.)
Reinhold (29 miles dia.)
Copernicus (56 miles dia.)
Clavius (136 miles dia.)
Tycho (52 miles dia.)
Bullialdus (37 miles dia.)
Anaxagoras (31 miles dia.)
Scoresby (34 miles dia.)
Just in case you don't know your way around up there, here's some help:
