Dave and Walter
New multi star PhD will indeed allow faster guiding cadence, and I also have found the mount best at higher cadence.
1.17 does not address what you are seeing Dave. At the moment we don’t see how firmware at 1.16 or higher can cause this.
Please post on the beta site some logs from the driver during this issue. The last files were empty.
Hi Wes, good timing
I’m doing the Crab at the moment
Still having issues unguided
Still doing the shift left shift right thing.
On 1.6 at the mo, would there be any improvement on 1.7?
Here I’m using 100% RA aggressive on a 0.5 sec multi-star guide! to keep it usable...

You might be already aware of this, but latest PHD2 build enables multi star guiding. There is a long thread on cloudy nights
I just wanted to mention it here since I believe it is especially relevant for weight-capable but entry level mounts like the exos2. my experience so far with my exos2 is that it needs to be guided aggressively. I typically have best rms with guiding exposures
of 1s, despite picking up a lot of seeing fluctuations. Multi star guiding should allow for a more accurate guiding with very short exposures by averaging out a lot of seeing (three times smaller rms due to seeing with nine guiding stars). Hopefully this
new functionality allows to push further the limits of the exos2 for astrophotography.
I will try it this week. Let me know how it works for you,
