Hi there,

How do you go about orienting your camera to frame the photo as you'd like (vertical or horizontal) when shooting DSLR with T-Mount? I imagine there will be many shots I'd like to shoot vertically, etc.

Thanks!

Although this  is 5.5mm thick it only adds about 100um to your backfocus (according to my micrometer) because the male and female threads overlap.

Remember, unless your filters rotate with your camera you will need new flats for each orientation.

ouch!

may be easier to rotate the image during processing instead of the camera.

For artistic composing and also to fit elongated objects into FOV, I would recommend a rotator. My TS 65 QUAD luckily have one integrated with the focuser.

The only caution I have found is that I have the WO rotator and it is quite thick. I discovered when I tried attaching the field flattener to it that the telescope could no longer reach focus on a DSLR because of all the extra length the rotator added. I think WO should have thought that combination through a bit better. The one David noted above looks much better because it is so thin.
