Hi SGPro Team,
I notice when I have my Esprit connected the auto focusing works flawlessly
When I am using my RC8 then the issue starts.
The auto focus although does a pretty good job is sometimes touch and go, an when evaluating the image, I find the smaller stars are out of focus, so I need to stop the sequence and do a visual focus by taking an image and making some small focus adjustments until I am happy with the results. Then continue the sequence run.
So I did some test and found the following.
If I slew to star-field that had very small stars the auto focus seemed worked basically flawlessly.
However, when I slewed not far from that field, that had Larger and medium stars as well as smaller ones. I would end up with the same problem slightly out of focus on the small stars.
Now, I know we have the option of changing the ‘Min star Size’ to get around some of these issues.
So would the following be a viable addition (option) and improvement to auto focusing.
Been able to nominate what size of stars that would be used for auto focusing.
For instance I would select min size 3 pixels to 7 pixels, this would ignore all other stars above and below the set values.
Of course I realize this would limit the amount of stars in the field for focusing but may improve the overall performance for the RC8 and other similar type telescopes.
