I am using a ZWO 1600 mono with LRGB filters. I also have a ZWO 120 using an OAG. I'm having trouble with the 120 set-up though. During calibration the process freezes and stops it's routine. When I try to close the windows I get an error message

I have been searching the forum for this issue but have not found it yet...

try connecting the 1600 using the ASCOm driver and the 120 using the ZWO native driver.

Would that mean in hardware settings instead of choosing ZWO for the 1600 camera choose ASCOM?

yes, in hardware settings. The idea here is there might be a conflict if both cameras are using the same driver, be it what it is. I have seen a lot of these instances when the cameras are from the same manufacturer, ZWO, QHY, Atik,....So, 1600 -> ASCOM and 120 -> ZWO Native driver

I guess I will actually have to use it in live conditions, yes? Would it work just sitting on my table connected? Without an actual star as a target?

it can be done indoors, just make sure they connect and can actually take picture. Could be a great time to take bias and dark frames

It is not working. When I try to connect the 1600 as an ASCOM I need to choose what kind of camera and the only options are simulators. If I leave it blank then the camera does not connect.

Also, if I disconnect the 1600 and just try to loop the 120 it still tends to freeze.

I wonder if it is the USB hub I am using. If it is causing problems. My new mount will not connect through the hub I have to connect direct to my laptop.

very good point John, USB hubs are the enemy of astronomy, I cannot emphasize this enough. They better be powered and of really high quality. How about plugging in directly to the PC? I use 15foot USB cables to avoid hubs myself.

Hi John, I had this same issue, Hamza helped me out with it.

You're not seeing the 1600 under Ascom because there is a seperate download on ZWO's site. I missed it the first couple of times I looked for it also.

Go to : https://astronomy-imaging-camera.com/software-drivers

The "native drivers" section is on top, that's the driver you need to install for Prism to talk to the camera "directly" (in actuality prism is talking to the zwo driver which is talking to the camera).

Scroll down to the ASCOM Drivers (optional) section, and grab the download for "ASI Cameras". This will install your ASCOM driver for the cameras.

I went through this exact thing with a 1600mm-cool and a 290 mono mini.

This should get you fixed right up.

I got myself a new powered USB hub and my cameras worked great. Then late in the evening they started acting a bit wonky again. PRISM ended up closing again one time. I downloaded the driver from the website (thank you rottielover) to have the option of connecting one camera differently from the other if I need it. Yes, that did work also. Will update as I learn the ins and outs...thank you for the help. Now, I need to figure out the right spacing for my two cameras so they both focus at the same time!
