just popped back for a couple of processing questions hoping you could share with us ( theres not enough discussion about this on IIS IMHO), being as it is definitely sharp but has a different look to it

during the processing did you use a high pass sharpening filter, not the variety in photoshop but one that sharpens just the high values, i think this is what makes it look different to me, i had a tinker with the one in WIN4AIP some time way back and had forgotten about it, i might have to have another play with it soon to see what it can do.

i noticed a sattelite trail to the lower right, what stacking mode did you use was it average mode, ive being using median of late although i usually run most of them just in case one gives a better result initially, ive personally found median is best about 80% of the time others swear by a sigma variety which might perform better in other programs than i have.

which brings me too how many exposures and length of time for each exposure and the camera.

cheers Alchemy
