Thanks Dennis, you're right! The one you've marked is indeed Pluto, and not the one I first thought it to be. Apologies to all for my mistake...
This is actually very interesting, I've just double checked in Starry Night and GSC 6269:1035 is not even on the map, in fact Starry Night shows no star brighter than magnitude 15 within 1 arcminute of Pluto at that time. Incredible - and very confusing.
This confirms a suspicion I've had for a while now. I've experienced similar difficulties before where the field I zoom in on in Starry Night looks significantly different from what I see in the eyepiece - very frustrating when star hopping (especially in Sagittarius!). There must be some errors in their database. Has anyone else noticed this? I'm just about to throw Starry Night out of the window now

What's your experience with The Sky Dennis, is it more reliable in general?
At least the correct Puto is also reddish, so at least that observation still stands

Once again, I sincerely apologise for the confusion. I have updated my image on the website.

Rolf
