How to see DSO on the computer screen

#1

Post by BentH »

Sometimes I use a mount without go-to. And then is it difficult to find DSO targets. What is the best procedure to see DSO on the computer screen? Is it one of the Fx facilities or?

Use the Display Histogram Stretch, which can be found at the right-hand side of the screen in the Camera Control Panel.

Unstretched, the DSO (M31) is not visible.

Stretched (by clicking the lightning button) brightens the display (note how the mini-histogram changes) and the DSO can be seen.

The M31 was a 90s exposure. You could try turning the camera gain high as a temporary step until you find the object.
