Is it possible to adjust lens focus step amount?

[robb42]

In the manual lens focus widget that appears when you go to Frame & Focus live view, there are 6 buttons for adjusting the focus (see attached).  Is it possible adjust the amount that the smallest step amount moves the focuser?  It seems like a finer amount of control would be useful for really dialing in the focus.

I'm using a Nikon D800 with BYN 2.0.10

Currently I do not believe so.

You may want to post your request to the Feature Suggestion Box Forum.

No, these are the actual step move supported by the SDK.

ok, that's too bad.  Maybe an SDK enhancement request could be submitted to Nikon?   I know it must be possible because I've used some INDI-based programs on the mac that let you program the step size, and you can do extremely fine adjustments.

All in all, I'm enjoying BYN - thanks for creating it!

An INDI Driver for NIKON Lenses??  Or a generic INDI Focuser Driver??

Your first step would be to identify which INDI Component and then ask that Developer whether they are using the NIKON SDK or something else.

If the INDI Developer has found a "Trick with the SDK", then there might be hope that Guylain can use that same Trick.

The program I was talking about is AstroDSLR http://www.cloudmakers.eu/astrodslr/
 

I'm not sure exactly how they access the camera - the above link talks about using the ImageCapture API via an INDIGO driver.   Also, the developer of that app told me specifically they do not use the Nikon SDK.

Based on the small number of supported cameras, AstroDSLR does not use either the Canon or Nikon SDK software library to communicate with the cameras. If so their list of supported cameras would be much larger.
