April 26, 2021 we released: SBIGudrv.dll update 5.0.2.0 with a date of 04-15-21. The update is required for customers with STX and STXL cameras using: SBIG Advanced Filter Wheel AFW-10-50SQ which is the new 10-position wheel for STX-series cameras SBIG Advanced Filter Wheel AFW-12-50R which is the new 12-position wheel for STXL-series cameras AFW-DUAL adapter and cables to stack a pair of these wheels for up to 19 or 23 filters. If you have other cameras or filter wheels, you do not need this update. sbigudrv.dll 4.99 build 7 is fine. If you install the update, it should not affect operation of your equipment. Please report any issues you encounter. The first line will show you this update. If you have 5.0.0.0 or 5.0.1.0 please update to prevent an issue with STT and STXL cameras and filter wheels. A MaxIm DL Pro update will be released soon to enable this functionality. Thank you to all people who provided us feedback on the early release.
You can learn more about the new Advanced Filter Wheels which are much slimmer and hold more filters here: https://diffractionlimited.com/product/sbig-afw-filter-wheels/
If you have some software dependent on the older SBIG sbigudrv.dll you can download this older driver package, and hit update. When it asks to check the internet for an update, say NO. Then it will use the local copy v4.99.
Thanks Colin - I got caught up in this today doing a reinstall of all the software in the BGO. Using the older driver with MaxIm 6.16 did the trick.
