Simpler than Adaptive optics?
I have a good idea which is so simple yet I don't see anything available.
A shutter on the camera set up to close whenever the guide graph goes over a certain preset limit e.g.
more than half a pixel or division.
I wish PHD guiding would have such a feature to control a shutter.
Sometimes when I am guiding a gust of wind might hit my mount -
if I could close the shutter automatically I wouldn't have to
discard the sub frame - just open the shutter when the mount had stabilised.
Is there any system like that?
cheers
Allan
