Dear all,

I am a happy owner of an ASI 120MM camera which I use for . I have tried hard to get my ASI120MM camera to guide through the ASCOM driver using the built-in relays via the ST4 port, but to no avail.

In PHD Guiding, it will correctly send guiding pulses via the ST4 port only if I connect to the camera via the native driver, but not using the ASCOM driver.

The same goes for Maxim DL: it won't guide using the ST4 cable when connecting to the 120MM camera via the ASCOM driver. Unfortunately Maxim DL does not provide support for ASI cameras through the native driver.

Bottom line: my tests clearly show that the ZWO ASCOM driver does not use the camera's built-in ST4 port for guiding. ?

My testbed is a 64-bit Windows 10 PC with all the drivers updated to the latest available version (up until two days ago). Selecting "ASI camera (1)" or "ASI Camera (2)" in the ASCOM chooser does not make any difference.

Is there a way around this problem? Maybe is it just some hidden configuration option in ZWO ASCOM's driver settings?

Any help will be greatly appreciated.

Thanks in advance

Hi Emmanuele，

Sorry for the problem.

For ASCOM of ASI Camera's ST4, you need to install another driver, it calls "ASICamera ST4 Telescope ASCOM Setup.exe". You can download it from our website. （It has recently been lost from our website and we will get him back soon.）

Dear Chad,

thank you for your reply.

I cannot find the executable installer you mentioned anywhere on your website. Could you please provide a direct link?

Or, if it is not available yet, do you have an idea of when it will made available?

Thanks

Emmanuele
