    Re: Limb corrections using a reflective artificial horizon
    From: David Pike

    Thank you Greg for the information.  Regarding the glass, it’s not so easy to buy a piece at any little DIY shop in the UK these days (probably EU regulations), so I bought a picture from a charity shop and used the 2mm glass from that.  Clearly, I should have bought two pictures and made myself a proper ‘rabbit hutch’.

     

     

     

    Regarding the semi-diameter question, if I shoot using a natural horizon, then I need to +/- one semi-diameter, 16’.  If I’m shooting limb to limb using a tray of oil, do I +/- 16, 32, or 64’?

     

     

     

    Steady for Astro
