SGP doesn’t have anything like this built in. You could leverage the SGP API and write a script to do that. Then you’d call the script from within SGP and have it disconnect the camera, run focus max and reconnect the camera. But the API doesn’t have any provisions for starting a sequence. The API is mainly made as an interface to the devices, not an interface to the automation.
You might just give this a shot in SGP. Here’s my workflow:
- Set focus points per filter in filter control panel (Define Filter List)
- Select the filter I want to focus Click the “Focus for Lum” or whatever the filter is on the Focus control panel
- Capture frame, see how focus is. If it looks relatively decent (Stars are relatively in focus) then run Auto Focus
- Continue running Auto Focus until a nice V is created.
In 2.4 things will be similar. Except that step 4 won’t require as much interaction and step 3 will allow you to have worse focus.
I would take a look at auto focus in SGP as it’s quite good (if I do say so myself). The only caveat is that you need to start in decent focus as the current focus mechanism relies on a fairly narrow window for focus. Really that’s the main change in 2.4 is that the focus window is larger and more deterministic.
