Have you considered a Sidereal Trading 10 f5 carbon fibre newt
Huge aperture, long focal length at 1250mm , easy to collimate and light enough on your big AZ Alt mount
A real galaxy hunter down there
Only one caveat, on a windy night , guiding will be affected but I use poly tarps from Bunnings and hook them up on some small trees around my 8 f5 when Im at Narrawallee and its windy and have managed to guide under 1 arc sec in 25 km/hr whilst imaging galaxies

Just a thought !
