ASI220mm Guide Camera is not working with MaximDL

SamS

I just bought the ASI220 guide camera. I'm using MaximDL latest version 6.30, ASCOM platform current release, and all the current ASI camera driver, etc..
I can connect to the camera but it gives the following error:
Error starting exposure
Could not set subframe or bin ASCOM properties.

Also, I have noticed the ASCOM window for this camera is not showing the Offset nor the USB Limit fields when the Advanced box is checked like all other ASI cameras do.

I have tried the camera on both Win11 and Win10 machines, sam problem
Any ideas.....

SamS Did not reproduce the problem in MDL,
Can you take a screenshot to show us your settings in MDL? and please also test the camera in ASIStudio, does it work fine?

About the offset and USB limit, does not support setting this yet. i will ask our team if consider supporting this in the future.

Hello Tech,

I'm not sure why you can't reproduce the problem on your MDL. I tested this camera on 3 other computers of mine. I get the same exact error in MDL. Also, I tested it on 2 other fellow astronomers computers in MDL with the same exact error. That's total of 5 errors out of 5 different computers.

I have total of 3 setups in my observatory. Two of them are using ASI174 and the ASI290 as guide cameras. They work perfectly fine using the same computers with the same settings. Only the new ASI220 gives the error.

I'm not sure now if something is wrong with the camera or it maybe an ASCOM driver problem with MDL.

Anyway I need to get this resolved soon as I may be running out of return period allowed by the dealer very soon. I will have to return it and get another camera model that I know it works such as the 174.

You asked me to test it using ASI Studio. It works fine with ASI Studio.

I also noticed that in the Offset/Gain Dialog window, there's an offset value of 200. The image I took using ASIStudio seems to have an offset value = 0 as it says ninth fits header. Just curious???

I'm attaching screen shots of MDL different settings relating to this camera for you to review.

1- ASCOM Driver Setting:

2- Camera Control Setup Setup Tab - Setup Camera:

3- Camera Control Setup Tab:

4- Camera Control Guide Tab:

5- Guider Settings:

6- Camera Control Expose Tab:

7- ASI220 error once I start the guide camera exposure:

Thank you very much for your help.

SamS Thanks. we reproduced this problem, it only occurs on the latest version MDL.
will fix it asap.

SamS

Great. Thank you very much.

Truly appreciate your help.

Thank you. I hope the updated ASCOM driver is out soon. I don't have access to an older version of MDL.

So I will not be able to use this guide camera till the release of the new fixed ASCOM driver.
