Hi Ray,


Well, I have to admit this is possible and I cannot know without checking. The OTA is remote so this is an ordeal to check first hand.


All I can say is that before I went remote I was using my Moravian G2-8300 with 31 mm Astronomik Type 2 filters. I found some old notes re filter offsets and the blue offset was totally normal. Memory says around 30-40 microns. When I first installed the DS set remotely and tried to use my auto focusing program FocusLock I had all sorts of issues. The offset was so great that the program could not deal with it at all. So, that is additional evidence that something may be up with the DS set.


However, I have not imaged with the Type 2 2" set and I simply opened the cases the way they were sent and installed. I don't recall verifying that the filters were in the correct cases. Stupid me. I admit that your numbers are pretty convincing!


Thanks for this!


Peter
