Your first diagram is reasonably representative of what the current WDS data indicates. To be more correct, your companion star would reside below the travel line given the present PA of 106.2 degrees. Possible answers to your query are:
1 - you are looking at the wrong star
2 - somehow your image is getting turned the 90d
The Delta mag of 6.07 is significant and in spite of the 2.21"of separation, this is going to be a tough split for 4.5" optics, especially if the seeing is below average. There is going to be significant glare even with good conditions. Are you tracking the star, ie, equatorial mount with drive motor?
I am sure I looked at the right star.
The star chart on the right panel in Figure 1 is actually what I see with the unaided eye.
My mount is a bog standard Vixen Porta alt-az. And as I said left and right are reversed in the eyepiece.
110 degrees or so actually would work.
Regarding glare. I took me 4 nights.*** The first 3 nights didn't really show the companion. But I knew there is something wrong because it was nearly impossible to focus the main star in bad seeing because I always ended up with a spike (where I now know the companion sits).
Any 4" telescope owners out there who want to challenge my observation. Would be great to get a confirmation or rebuttal (also for Delta Ursae Minor).
***I don't think there is a good correlation between Jet Stream and seeing. Although it is true that good seeing often comes with a low jet stream (you can zoom in and click on your location to get a value forecast: http://www.chilescop...tream-forecast/ ). But on Thursday 2nd Jan 2020 the seeing was quite good for zenith regions and also the jet stream at my location was very low (<<40 knots). Also in my valley with a Bortle 3 skie often you wake up in the morning with heavy fog. This means visibility is often not that great while observing (fogs starts to slowly build up during the night) but this helps with double star glare issues. For example NGC 2403 (mag 8.5, 23'x12') is an easy object for my Vixen. But NGC 4236 (mag 9.5, 23'x7') is a very difficult object.
