These were an attempt at double stacking a Quark Combo with a PST etalon at 2700 mm f/15 with my 180 mm mak. The combination gave darker views at higher f numbers but useable exposue at f15 together with a sizeable ghost in the upper right in the first 2 images. Significant cropping had to be done due to unevenness over the whole frame but the lack of a double limb suggests that very narrow bandwidth
is reachable with this combination.

It came out well (reflections cropped!), it always fun to mod and play Lou!
