Can you elaborate on the high pass technique?
Is the filter your'e using a 2"?

Thanks for the comment.
Yes, the 2" filter attatches to the barrel of the coma corrector, which doubles as a t-adapter.
I picked up the high pass filter technique somewhere on the web, but I can't find the reference just now.
This technique allows you to enhance some features in the image while leaving the rest of the image unchanged.
This is what I did:
Start with a flattened image that has undergone normal processing with levels/curves etc. This type of processing often looses a little detail in some areas of a DSO (eg dust lanes in a galaxy or nebula).
Duplicate the layer (background copy).Make sure the top layer is selected. Apply the high pass filter using filter-->Other-->highpass. You may need to experiment with the radius a little to see what works best. I used around 50. If you want you can also apply some sharpening to this layer
Set the Blending for that layer as overlay. This creates a high contrast version of the image that looks too dark
Now create a mask for the layer using Layer-->Layermask-->Hide all. Your new layer now seems to disappear.
Select the layer mask in the layer pallette. Select the brush tool with White as the forground colour. Using as fairly small brush and zooming in, paint over the details that you want enhanced. This is actually painting white on the black mask, allowing the enhanced layer to show through.
Once you are done you can fade the effect by reducing the opacity of the layer.
That's it.
Cheers
