Willoughby - WOW, beautifully done.
What lens? Looks slightly wide angle'ish, nice and crisp despite some slight star movement.
Shutter speed not all that long as stars not very elongated at all (just a tad)
High ISO? or did you stay around 400 or so?
Reilly, nice couple of photos there mate. Macquarie quite pleasant, some slight misty remnants about.
Shot from Mt Vic very good. Mt Lambie just left of centre, Hassans Walls pretty much centre.
HASSANS WALLS is one of the absolute best lookouts around, if anyone travelling by, take the time to get up there, more than worth it.
