ASIMeteorCap problem

johnpd

I thought I would try taking some Perseid shots using my ASI662 with the fisheye lens. I mounted the camera on a tripod and started ASIMeteorCap. I had to set the exposure to the max (1000ms) and gain into the 500's. The sky then appeared nice on the screen. My skies are Bortle 4. Initially I got some false positives but did catch one. As time went by I got no indication that any meteors were being picked up even though I could see some nice ones stream across the screen. I don't know what happened. I am using v1.11 of ASIStudio.

Edit:
When I shut down, I ended up with an almost 2 hour .AVI file as it found nothing for that length of time. When I looked at the file using MS Media Player or Movies and TV, they hit an error saying the file was basically corrupt. VLC will not open ZWO ASI files at all.

johnpd Sorry for the problem, what is the value of monitor settings?
Could you try ASIVideo stack? can it open the AVI file?

I had exposure set at max (1000ms), Gain at about 550, Sensitivity at 90. I saw a video for using the ASIMeteorCap where that person had the exposure set at 64ms. I don't know how he got an image. He used an ASI224MC camera in his demo. I would not think that there is such a difference in cameras. I loaded the almost 2 hour image into ASIVideoStack. It was able to stack it. I have attached the image. It shows field rotation as expected as the camera is set on a tripod. I used v1.10.3 of ASIVideoStack for this.

johnpd I think 1000ms may be too long for ASIMeteorCap, hard to reach the capture requirement. Short exp may be better.

I also conveyed to our devs, we will optimize this as soon as possible.

The problem is that in order to see the sky, I need to expose that long plus push the gain way up. I don't understand why. Thanks for having the devs look into this.
