My fast Newt is a Vixen R200SS (8" f/4) that was purchased used but was NIB condition. I  dropped it on the concrete garage floor before first light which destroyed the focuser. The complete abbreviated story is here.  I've installed a rear fan, machined the spider vanes and moved the primary mirror forward to accommodate the focuser. 

Corrector for f/4: TSGPU

Corrector for f/3: Starizona Nexus

Main imaging camera: ASI2600MC-Pro (APS-C)

I'm using SW Quattro 150p with his native coma corrector, reducing the focus to 517.2mm, according to Sharpcap platesolving.
