FYI - Multi Star Guiding with PHD

Just in case somebody is interested in this. Saw that PHD has a dev version out with multi star guiding. And of course I had to try it. Definitely is better than 1 star guiding as far as I can see. I use the MyT from Bisque which is of course a nice mount, NO PEC. I still went with 3 second exposures, it might be actually better with less!

To activate this new feature selects the "brain", goto guiding and select check box "Use multiple stars". See version C.

Description: With 1.5s exposure time, roughly same RMS as with the 3 seconds, but peak is less than 1.3", that makes stars really round. Dec and RA as well pretty similar, even rounder. I checked with PI the raw data and some of them had an eccentricity value of 0.32, do not believe that I ever saw this low value of any image that I took. This is great stuff! Thank you PHD!

Description: Just to confirm that the multi star guiding is working pretty well. Not all images seem to have the same quality, but overall it is looking pretty good!

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
