Re adaptive optics tilt mirrors...

Antonio Cididao used to take planetary images using an AO-2 from

Stellar Optics

http://www.astrosurf.com/cidadao/equipment.htm

I think he told me he'd bought it used, as the company wasn't making

any more amateur devices, and the versions for professional astronomy

were, well, astronomically priced!

The AO-2 differed from the devices from SBIG in that it used a lens,

like Starlight Xpress does. But unlike the SX device, it worked fast

enough to use for planetary imaging.

Wish I could find one. I have an AO-7 for my ST2000, but the back

focus is too long for imaging with a focal reducer, even on an SCT.

And without one, the focal length is too long.

company called Phisik Instrument especialist in

nano-piezo-actuators for Microscopy and other stuff

including adaptive optics..

They sell whatever we could need.... the smallest

mirror tilting was priced approx 15.000 US$. ROFLMAO

AGAIN

Yep. All of those mirror type things are expensive and delicate

little beasts. Making the code work too is not easy either, as Darryl

Robertson has done adding A07/A08 support for SBIG in Equinox Image.

They have lot of nanopositioner for microscoping

(tolerance 1 angstrom).

Did you hear about them?

No I don't know of them specifically. I talked to a few microscopy

people about adding support for some motorized stages, however most

felt like it was not worth it.

Very interesting stuff.

A question on-the-fly: can i install QuickTime 7.2?

Apple now require it in order to run iWork 08 :-(

Yes and we tested with QT 7.2 / 7.3 too. If your recording color

movies, you should install the Universal version 3.0 Bayer Codec for

x86, which is included in the 3.02.03 disk image.
