The STC-7 works 100% correctly with Maxim DL (congrats on a complex device working so well). In using it via TS-X I selected camera - DL via Maxim. The filter choice was odd. At one try, there was a DL filter selection and choosing it did not detect the filters(*) although it connected. Choosing ASCOM filters, did not connect. Is there support for the CFW of STC-7 in TS-X? ---- Q2 - Temperature setpoints - How low should the temperature be set? If the outside temp is 0C and the camera can reach -30c with 75% power is it worth going to -35c or -40c assuming the sensor does not frost over? Software Versions: Windows 10 Pro - 20H2 absolute latest Maxim 6.26 TSX - absolute Latest Daily Build ASCOM 6.5.1 3234 SP1 DL API - latest DL ASCOM drivers should be latest. (*) the TSX software said the resply for filters present returned none (no filters at all).
