Hi, yesterday I could finally try the Panoptic 22 I bought with my Dobson 200 (f6). The issue was that 2/3mm intra-focus were missing by using the 1,25inch. Of course I could get to focus by using the 2inch, but as all my other eyepieces are 1.25inch, it was nit convenient. Thanks to the forum, I found this old topic:
It was easy and fast, of course take your time and be very careful.
