Ta...the only adjustment I had to make was a slight primary collimation tweak....the secondary was dead-nuts on. Not bad considering it was shipped from Europe.

The field corrector spacing won't be optimal until the precise parts adapter shows....that said, looking at the off-axis stars the correction looks pretty awesome already.

Alluna have a few more software tweaks in the pipeline..eg: focus tracking

The attention to engineering detail has blown me away, it makes my old RCOS look clunky.

From the pin-point secondary collimation spot to oversize stainless bolts, collar locked electronics connectors, sequenced robotic mirror cover flaps that fully overlap when closed, 18 point mirror cell, carbon fibre shroud etc.

The interferogram shows a Strehl of around 95% with not even a hint of a turned edge.

I'm really looking forward to getting some serious data with this puppy
(actually more of a Rottweiler )
