Re: Best Score option in the Focus Graph
Hi,
ah, yes, I removed the 'Goto Best Score' button in SharpCap 4.1 for a number of reasons...
1) It was very rarely used
2) It could be unreliable if on the second scan it didn't find as good a focus as on the first scan
3) The only real justification for it was to deal with focusers that couldn't accurately return to the same position for the same focuser value
Backlash can be a cause of not being able to return accurately, but SharpCap now has multiple ways to deal with focuser backlash that will eliminate that problem. That meant that 'Goto Best Score' was only really helpful if you had a focuser that was mechanically unreliable or slipping - for a well behaved focuser, Goto Best Position works more reliably, faster and gets you the best focus accurately.
If you have a look at the updated documentation for SharpCap 4.1, you will see that it's been replaced by the Refocus button - https://docs.sharpcap.co.uk/4.1/#(Nearl ... 20Focusing
cheers,
Robin
