Astrophotography setup

[Robfal]

 

Telescope setup.  Up until now I have been imaging with an atik 314L + on a skywatcher 200Pds Newtonian (F5 FL 1000mm) with a separate guide scope (Orion E80  F7.5  FL 600mm) in side by side mode. Used to have a very Old Qhy5 so could not use a OAG (have a TS OAG).  Now got a much more sensitive Zwo120mm mini guide camera.

 

What set Up would be best

 

1) stay with same setup

2) Newtonian with OAG.  

3) Orion Ed80  with OAG

Benefits of single telescope setup is lighter payload and no torsional loading

Would I benefit from a focal reducer or coma corrector?

If I was to change camera what should I get

Thanks in advance for all help
