My last thread got lots of hits and was a success so I thought I would start another discussion based on the Galaxy I was speaking about, In my previous thread we found the distance to the galaxy, now I want to take this further and work at the diameter of the galaxy. If two edges of this galaxy are 4.0 arc minutes apart then to work out the diameter would it be Dia = Distance/Arc Min?. I'm not complete sure about Arc Mins and that formula may be totally incorrect.
