Is Adaptive Optics worth it?
Hello:
I thought with those professionals (telescopes) version of adaptive optics
what they do is somehow aim a laser into the air in the direction of the sky they're wanting to image.
And then based on the image of it they see reflected by picking it up in a side scope, the imaging program knows (somehow) through programming how to make the changes in the image picked up by the main optics.
It's really interesting. With the first case, the change to the final (main) image is done through the computer. But then there's seems to be a version where the main image is manipulated by having actuators on the back of a reflective mirror. And these are manipulated in real time while the image is taken to counter act for bad seeing and for mistracking.
The version of AO that SBIG and Orion is selling doesn't use a laser to shine. But I believe use that actuator idea.
Can anyone here tell me if (if money wasn't a problem) would AO by one of these suppliers be worth it.
Like they say it does better than Autoguiding alone. And it takes care of seeing problems as well as tracking problems. So it a pretty attractive idea.
And PS: is SBIG's AO compatible with any of the SBIG camera's, or specifically the ST-2000? And with respect to that earlier post someone did on CCD's, how does "ghosting" and QE have to do this these cameras?
I know for example if you want to see the type of chip (for SBIG) cameras, it's on their website beside the name on their price page.
Thank you.
