A second run out for the new PST double stack module; a distinct procedure meant setting the etalons up with respect to each other and the OTA was much quicker. The left hand side of these images is out of focus due to some slip in one of the adapters, but have made a new one of these now so should hopefully remedy it. I'm really liking the extra detail double stacking brings out, in particular on filaments as can be seen in this image taken with the 70mm scope, 1.6x barlow and DMK31 camera.
