iOptron Photron 8

[RolandKol]

Hi guys,
I need a small advise... Planning to upgrade from my Skywatcher 130PDS to iOptron Photron 8" Ritchey-Chrétien...
Will sit on NEQ6, guided via OAG. Shooting will done via ASI1600M-pro...
Strange, but I could not find almost any info online in relation....
Questions:

1) Could not find any reducer for this scope, - are there any?

2) Does this particular Photron needs any type of corrector?

3) Colimation - any special tools? or I can use the same Cheshire from Newtonian?

4) Saw quite a lot "fat" stars online via RC... is it scope specific or just newbie processing mistake?

5) if not iOptron, - what about GSO or TS-Optics or something?

Or simply/painfully cash out for EdgeHD8/9.25....

P.S.
Shooting DSO mainly....
