It's possible but going to be really tough. Baader AstroSolar film is also pretty fragile to be carrying around when traveling overseas unless you can have it shipped from Germany to Turkey.
If you have a DSLR camera, I would recommend a telephoto lens with a screw-in Hoya Solar filter. Something like a 250-mm f/6 for an APS-C camera would be just about the bare minimum. With a 27-mm sensor at 250 mm of focal length and f/6, you would have about the equivalent view of a 9X45 binocular, but with much greater resolution due to the small pixels on the sensor. But Mercury would still only occupy a handful of pixels. It's really small.
Something like this on a photo tripod is likely going to be a much better and safer option for you:
You can use that visually or with a camera. It has a built-in permanent nonremovable Solar filter so is very safe for travel.
Something from the Celestron EclipSmart series may also be a good option for portability and safety when traveling for Solar events. But Celestron EclipSmart uses yellow-light filters instead of white-light filters.
