Its just under 1200mm focal length so its already longer focal length than your TOA150!
Around 1200mm focal length is a sweet spot for a lot of objects.
Plus even if you used a 1.6X or 2X extender that could handle the STX16803's large sensor you'd still be under F7/8 for smaller galaxies.
So that fast F3.8 can make it very versatile.
