Filter size for esprit 120

[Kuz]

I have finally purchased my dream scope a esprit 120 .I am currently in talks with the finance minister (my wife) and I am looking at purchasing a zwo asi 1600 pro camera soon to go with the new scope., and take the plunge into narrow band . My question is can i use 1.25 inch filters or do I need to go to 31mm or 36mm filters .

Thanks

1.25" will do just fine on the 1600MM as long asyou place the filterwheel right on the camera without any spacers (which you shouldnt do anyways)
