thanks all for your comments.
yes gary, it wasn't a easy target to capture good detail though i was a little worried when there where spots of no stars i thought DSS had stuffed up or something

Thankyou doug I must say that the ed 80 provides a pleasing wide field vista. im looking forward to tackling the rho opphicuni nebula in scorpio this year with it. might have to mosaic but all good
