* '''February 2024: a new autoguider system [https://topswiki.saao.ac.za/index.php/74%22_/_1.9m_-_Instrument_Selector instrument selector] and [https://topswiki.saao.ac.za/index.php/SHOCnWonder SHOC camera ] have been commissioned on SpUpNICthe 1.9m''', which means that '''SpUpNIC and SHOC users now need to log into a new TCS PC, tcs74v4.suth'''. For the time being, HiPPo users will continue to use tcs74v3.suth. This completes the second phase of the project to install an Once complete this instrument selector on the 1.9m, that will allow both SpUpNIC and SHOC, or HiPPo and SHOC, to be mounted together on the telescope. The It incorporates a new autoguider that operates slightly differently from the old one - changes include:
** It is no longer necessary to initialise the XY slides at the start of the night, only if there is a fault, in which case the "Reset" and "Initialize" buttons will turn red, and should be clicked in that order.
** The XY slides centre position is no longer (0, 0) but (7150, 82000). The new "Center" button is now used to bring the XY slides back to that position, no longer the "Initialize" button.
** The new guide camera field is larger and the chip has far fewer hot pixels to upset the guiding.
* '''May 2024''' - the '''windblind is still out of action'''. The new design has passed the review stage and is ready for parts to be manufactured.
