These images are part of a little experiment I am doing in digiscoping, or using lower cost optics designed for birding or hunting/shooting sports and coupling them to lower cost camera equipment to obtain some pretty impressive reach. This first set of images comes from an older Zeiss spotting scope coupled to a older, little Canon Powershot S100 camera with the idea of getting the best possible quality images out of this setup. There are a few advantages of this setup including the Zeiss glass and the Canon SD100’s ability to shoot RAW at a 45X magnification factor. The next set of images will come from a different setup… More to come on that.
These images are pretty decent, though there is some aberration near the edge of the moon which was closer to the edge of the image forming portion of the light beam on this particular setup. This is essentially the setup taken when I was shooting the ring of fire eclipse last year, minus the heavy duty ND filters of course.
This was one of the best shots I could manage on this night at least of the seas of the moon, in this case the Mare Tranquilliatis were a bit soft and not as crisp as the other images. Could be atmospheric effects, but probably are more optical in nature from this scope combination.
Zooming out a bit there is some chromatic aberration seen in the upper right portion of the image as a blue corona. Some of this can be corrected in post-processing, but the idea is to see how these hold up with the next set of experiments. All told, these are reasonably impressive images from equipment that was not purpose built for photography, but I think we can improve on this some. More to come when I get some custom built hardware solutions…
