Thanks folks for your suggestions. I am actually trying right now to find out how to shrink my photos to a size I can send. The JPG photos are around 4MB. How can I make them smaller? Cropping?. I focus by setting up in the daytime focussing on a far away hill (probably 5 kilometers away) Then I get masking tape and stick down the lens at the best focus. My lenses are Samyang manual only so I have to set focus manually. I set the Pentax to MF mode. The Astrotracer seems to work really well, because there are (mostly) no star trails, and some shots I have taken at 120 sec exposure.
I will try and post a photo asap
