I've just received my new TS Optics 130mm f/7 triplet (with the 2.5" focuser), and was disappointed to realise that it doesn't include a finder mounting bracket.

 

It's also not completely obvious where this should be fitted. There are some screws on the tube directly above the focus knobs (see photo), which could do the job, but only the central ones appear to have a flat surface, and this is very narrow.  It also seems odd to place a finder directly above the focuser and not offset to one side to make it easier to access without getting in the way of the main diagonal & eyepiece. The 2 screws are aligned along the axis of the tube instead of perpendicular (which unlike any other finder bracket I have seen on multiple scopes that I have owned).

I've seen that some users put another rail on top of the OTA rings, and mount the finder on this.

 

I know this is sold as an imaging scope, but it seems a bit cheap not to include a basic finder bracket on it, which could also be used for a mini guide-scope.

 

Any suggestions for the best location for the finder?

 

Thanks!

I would use this base: https://agenaastro.c...nder-xfurb.html

on either the top or bottom 2 screws in your photo.

I have two TS Photoline APOs and have never worried about finders on them.  If your properly aligned then finders are a waste on imaging scopes, you can just look at what your camera sees - the whole scope becomes a finder.

 I have my SV 50 finder mounted on the back ring of the WO ZS110 with a AT red dot finder on the focuser which is offset to the left side. David

Looks like you have the 2.7” focuser. I also own this scope and would assume either of the side mounting screws would be the spot. I dont user a finder so I’ve never tried on this scope. I have been thinking about getting one so I’m interested to find know what others are doing.

I just checked on my AT 102ED and I see I have a base with just 1 mounting hole. It's plenty secure this way. Looks a little crooked though. I've got bases like the one I linked above around here somewhere....

...I think the screws in the middle are not meant for the finder bracket, its the screws left and right to it.

Alternatively you can mount your finder on the rings:
