Quote: I have had a similar issue with my Solarmax II ds . The internal etalon assembly is screwed into the focuser . The base of the etalon should be snugged tight into the focuser and the adjustment ring (the ring with the adjuster post)threads to the base piece of the etalon . I have been using my scope in sub freezing weather , the adjustment ring became snug enough to loosen the whole etalon . So what was happening was instead of adjusting the etalon I was threading the whole etalon assembly in and out . It was quite obvious what had happened because the adjuster was loose and the view did not change . If this is what has happened to your scope it is an easy fix . I had mine apart to replace the focuser with a Moonlight and did not get the etalon tight enough . The scope un screws just in front of the slot for the adjustment pin . remove the pin and unscrew the focuser from the scope . the internal etalon assembly should be tight into the focuser and the outer ring should be able to rotate freely . If the etalon is loose in the focuser remove the outer ring section and tighten the base then thread the ring back on but not tight . Now re assemble the tube . In my scope the etalon comes into band just as the adjuster starts to get snug . Rotate the adjuster ring until you find the sweet spot and then re install the pin .Hope this helps , I have an instruction sheet I will try to find and send you if you are interested .
