which active optics

Hello fellow astro friends,

I'm looking to use some active optics on my settup. I would like to hear the opinions of others who have used them please...

I use a Planewave scope 2.5m FL and a stl11000 is used on it. So my two options are a Starlight Express active optics or the SBIG Aol with a MOAG. I understand there is a large SX AO for full frame chips.

a few things that i ponder... I straight away think the SBIG Aol is better just cause its tried and proven but i have no evidence to think the SX AO wont perform.

- how does the quality of the 2 options compare?
- The maximum number of HZ for each unit?
- with the SBIG Aol I am stuck with using the RGH, but im guessing with the SX AO I can use other brands of guiders or the loadstar which would be more sensitive then the RGH.
- That raises the question of how to do auto darks on the Loadstar when doing automated imaging as it doesn't have a shutter as I understand??

If anyone has any experience they would like to share on this topic, id love to hear it

Thanks, Josh.
