#Is this ok

    Still not sure about arc- seconds as I understand it the red cross is 2.0 arc-seconds but When it comes to the following differences then I start doubting how much change is too much : NED NVSS J184308+072703 RadioS . Against :Wise ID : J184307.43+072817.7 Separation 1.252 there is no SIMBAD . VizieR

    hi,

    the separation is 1.252 arcminute, which should not be mistaken for 1.252 arcsecond !
    this radio source is far away from the central wise object here, J184307.43+072817.7.

    concerning this source, there are multiple objects in the red circle and it's extended in WISE.

    Hi anoxie ,that has helped me a lot I was aware of arcmin and arcsec but not sure about distances . And I was not taking into account the other objects in the circle which will change as of now . I will also look harder at the documentation , to determine Minutes and Seconds and try and use the red cross 2 arcseconds Wide/High as told to me by voyager1682002 sometime ago . Thank you for your help . Cheers , Ian 😃
