Following the release of the Adaptive Focusing System, we received a lot of feedback from the community and there were primarily two large issues that we kept seeing.
The first of the two biggest issues that we noted from feedback, is that often the system would focus during an imaging session, leading to failure of that sessions purpose. Primarily this affected our Research Community, NEO hunters and Comet Hunters.
The second is that they systems can often be overly sensitive to ambient temperature change, leading to small focus steps happening too often.
With that in mind, we have a new update that was rolled out last night to all systems and another update that we are working on for the near future.
The update adds a new directive, #NOADAPTIVEFOCUS, that will shut down the Adaptive Focusing System during your run.
This is a new directive that members can now include in their plans to shut down Adaptive Focus during their runs.
This means that once the imaging session begins, there will be no focus the entire run - this includes at the beginning of the run.
So, the system will maintain it's last known good position and will continue to make small adjustments in focus, but it will not leave your target to slew to a focus star and perform a full focus run during your session.
This directive has been released and is working on the systems now, however until we can update the User Interface, the only way to enact this directive is to directly modify your .txt ACP script, by adding the line, #NOADAPTIVEFOCUS before the imaging directives (#interval, #binning, #filter, and #count).
To assist members that are not yet familiar with ACP script writing, we have a couple FAQs we suggest taking a look at:
Temperature Based Focus Adjustments
For the second problem often reported - systems performing small focus position changes based on ambient temperature without the need of a full focus run - we are currently in the process of updating some of the algorithms the system uses to ensure it performs more accurately and overall makes less unnecessary adjustments.
As this is still being developed, it will not go live right now, but you can anticipate a less sensitive and more accurate system in the near future.
