Lovely image and worth getting up early.

There is some red fringing around the fork in the tree. Is that due to the HDR process?

Curiosly enough, we do. It's called Paginas Amarillo (Yellow Pages)

Lovely garden, but is this an appropriate scene to test such a filter?

Those are actually the same shot 35mm - f32 - 1/10 - ISO400 (check the EXIF data), which is why I can't see any difference You've linked to the same image in both cases.

I'd thought that the primary use for a 10 stopper would be where flowing water or clouds were in the scene, to give them that creamy look.

Do you have a local industrial tool/welding store?

If I do, I wouldn't know what it looked like, or what to ask for when I got inside

Yes, and I sold it. I found it a bit slow and soft wide open at 400mm. I now have the 150-500mm and am very pleased with it.

Out with camera set up on tripod few test shots without glass ok , set to bulb, remote, out with rubber bands to lash it to the lens and dropped the blinking thing!! they don't like hitting the ground. picked up the bits threw them in bin try again when back from hols.

Good job it wasn't a £100.00+ Lee filter then.

When a long exposure is finished the camera creates a dark frame with an exposure of the same duration, but with the shutter closed. In camera processing uses this dark frame, which is basically made up of sensor noise, and subtracts that noise from the main exposure.

Some Pentax models allow you to turn off this NR and you can perform the noise reduction in PP, but you may need to make your own dark frame to be succesful in reducing the noise levels to a minimum.

You don't say what you are photographing. Is it static or moving subjects? I'd suspect the Pentax SR isn't as good for moving subjects. Peter refers to the Sigma 150-500, well that lens has 2 settings built in. One for static and one for panning. The Penax bodies don't have this.

SR or any image stabilisation system is no good at all for moving subjects, fast shutter speed is the solution to that problem.

Wonder what setting number 2 is for on the Sigma 150-500 then? I thought it corrected vertically, but not horizontally so that when panning it didn't try to compensate for the horizontal movement of the camera and lens. Further info would be good to correct my misunderstanding.

Your understanding is correct. At least, that's my understanding if I've understood the manual correctly.
OS option 2 on the 150-500mm allows for vertical stabilisation only.
