Using Phd2 w/ SBIG 16803, SBIB A/O, PWI4, and NINA

[Rick Wiggins]

Hi Group,

I am trying to use Phd2 with SBIG 16803 w/ AO, PWI4, and N.I.N.A.

Is this possible? Is there any information that might help me with how to do this such as settings?

Thanks for helping,

Rick Wiggins

Here's a link to past conversations about the SBIG AO devices:

Bottom line, you won't be able to do it, but with a high-end mount, you may not need to worry about an AO.

Hi Bruce,

Thanks for the response. I will be using N.I.N.A. and Phd2 in the future in multiple applications. I do like the results that SBIG A/O produces. I have found it gave a slight advantage (ultimate resolution) over simple (one star) guiding on CDK-17 with Paramount MEI and MEII and CDK-24 with L-600 Planewave mount.

Thanks, Rick

I think it's fairly likely that multi-star guiding in PHD2 will produce excellent results.  It's being used without an AO on many CDK setups similar to yours and the results are pretty much seeing-limited - often in the 0.2 - 0.3 arc-sec rms range when conditions permit.  You should read the section in the User Guide on guiding high-precision (encoder) mounts:

Good luck,
