Im using a C925, 2xBarlow and a ASI 294 MC Pro OSC camera. SharpCap Pro
I’m trying to capture Jupiter at a high frame rate.
When i reduce the region of interest to something very small, the planet disappears. It doesn’t appear on the sensor anywhere, as i move the ROI systematically to find it.

It reappears when i bin 2x. Is that what’s meant to happen? It makes the final stacked image quite blocky.

It happens at a certain point of ROI. Before that point i can find the planet by coursing around the sensor, after that point, it’s nowhere to be found until i bin.

An explanation/solution would be really appreciated.

Cheers
