I have an old Canon Rebel XS, the 1000D I think, and no mention of a port for that one. Things may be moving on the Fuji front, but it isn't magic lantern. Things about firmware, scripting, and a hidden menu. I am looking into that aspect now. Using the point and shoot has been a learning experience. I wear glasses already for reading, but put on two pair of readers on top to look at the camera's screen. I discovered that the more distant a crater was from the terminator, out in the mares they were faded so to speak. While twisting the helical I noticed that a small crater's contrast would jump up a bit and the crater would be just a little more distinct. That seems to be where the best focus was. 3km craters are specks, but 7km and up craters show nicely. I do one thing with the camera mount, and that is to center the lens as close as I can to the eyepiece, and turn on the camera to ensure it is centered in the screen and aligned by looking at the inside of the eyepiece barrel. And even then the whole contraption I have can move slightly once on the scope :). Next time it is clear it will be either a 25mm eyepiece or 4k or perhaps working up to both :)
I'll see what I can find about the FinePix XP140.?
[edit] I had to disable autofocus. I allowed it a focus once on camera click/trigger and then possibly adjust the focus again if needed.[/edit]
