Since the value for keyword instrume and telescop equal the same “Seestar S50”. And the telescope name is exposed in the Seestar app… could your engineers allow for changing the value for TELESCOP with a user defined value. This way your customers can distinguish fit images when taken from one Seestar to the next when they own and use multiple Seestars. An alternative is to add another keyword pair with the serial number and proper UID universal Id for the telescope. I and many others have noticed we sometimes get duplicate file names when me download images on the same target at the same time since we often use multiple seestars on same object.. would be a very useful and universally standard compliant enhancement. Surprised the industry does not have this in the fit standards. In addition adding the value to the firmament would also be useful or at least the ability for the user to add it..thank you
