Processing issue ZWO 6200 MC pro  

A black screen usually points to a data calibration issue. What happens when you integrate without calibration? You're sure you have stretch selected (on the right-hand side of APP)?

@vincent-mod

Yes stretch is ticked.

stupid question- how do I integrate without doing the calibration first - you mean just integrate Light subs only ?

@gilgm Just load the lights and no calibration. Then go straight to tab 6 and click the integrate button. APP will take care of the intermediate steps. Let us know please if the resulting image is black again. It shouldn't be.

@wvreeven

Will give it a go and let you know - thanks .

Hi Wouter - Just did the Integration - Final integration is black again - individual subs all look OK - not sure what is happening ?

Interesting, could you share your data with us so we can better see what might be the problem?

Go to https://upload.astropixelprocessor.com and for the username and password, use: upload

Create a directory named “gilgm-blackIntegration” and upload in there. Thank you!

Hi Wouter

I have uploaded 5 Light Subs as requested to the Directory 'gilgm-blackIntegration'. They are large files 117MB each.

Interestingly I didn't get a black integration. Could you check what the OpenGL button says on top-left of the APP window? And if it helps if you press that to switch GL off? Are you using APP 1.082 or higher?

Many thanks That worked ! But what does GL off do ? I’m on version 1.082

That button switched off OpenGL which is used for faster processing in the image-viewer. If that helps, there is likely an issue with your graphics drivers on your system. Maybe you have a conflict with 2 drivers? Sometimes people have both Intel and NVidia etc.
