doh!
I've been doing some digging around regarding the red cap I observed on the nova which looked just like it did in Tom's pic just above. I took it up with Bob King who's been a long time member with AAVSO & writes for Universe Today, so I thought if anyone would know he would.
Nope. No red cap. He did say it has "a distinct reddish colour" which I did observe as a pink hue. He said he was puzzled about the red cap I saw as it's so far away that it'll only appear as a point of light.
So I'll put it down to the seeing conditions which weren't great that night. But it puzzled me why I didn't get aberration on the other yellow stars in the area as I was trying to deduce that.
Maybe because it's got a pink hue, the seeing affects it more?
Oh well... seeing the pink hue was a thrill in itself.
And I didn't imagine that.
