Some days ago I had shot OU4 with my 130/910 mm apo and 0.79x reducer. But it was too much focal length and also I messed up the framing, So OU4 was stuck at the outmost edge of the frame and I did not like it. Furthermore the effort of isolating the Squid had been to much to let it be like this.
So I used the 80/480 mm TS Photoline triplet apo with the 0.79x reducer (380 mm) last night to give the two beasts some room.
