Quick update – there is now no upcharge for ISCG mounts (Hammerschmidt or standard) on:
Helius AC, Helius AM, Helius AFR, UFO-ST or Ion-ST.
It continues to incur an upcharge on other frames where it is possible (eg Argon FR).
This applies to any orders already placed where you are awaiting delivery (ie where we have not been invoiced). If you want to add ISCG to any open orders we will charge a £50 “order change” fee (this fee now applies to all changes to orders after they are placed with us).
