For those who want to replace the stock 1.25" tripod in order to increase the payload limit on their iEXOS-100, you have two options:
The ES Medium/Heavy Duty tripods are not available in the EU. Here is what I did. I approached my local Bresser dealer (Bresser UK) and asked them for the Bresser version of the ES ST2 tripod. They got in touch with Bresser headoffice in Germany and my ST2 tripod was delivered by UPS 5 days later. It costed me £135.
Skywatcher 1.75" EQ5 tripod:
Out of curiosity I tried my iEXOS-100 + Fine AZ adjuster on my SW 1.75" tripod that I normally use with my HEQ5. The combo worked flawlessly. So for those who can't get hold of the ST2/3 tripods, buy a SW EQ5 tripod instead.
