How feasible is it to integrate with the liveview/video stream? That would be ideal.

This is awesome! Many users have requested this feature before. Though I am quite spoiled with the autofocusing and my bahtinov mask is collecting dust now :P


Please don't give up on the autofocuser. That works fantastically and is indispensable when running an automated image acquisition sequence.

Both have their place, but I don't see how a Bahtinov mask focusing mode could be integrated into the scheduler.

Autofocus is great, but not everybody is setup with a motorized focuser. A bahtinov mask is a quick and reliable manual method. It works well by eye, and better with computer guidance.

Hey,

the autofocuser based on HFR will not be affected by this and stay the default option.
In fact it would be possible to use the offset calculated by the Bahtinov fitter to drive the autofocuser.
In a fully automatic setup this could be combined with a mechanics that places the mask onto the scope (similar to what some people have for flatfield caps). But we are digressing.

For the streaming mode we have to see. The fitter works on the image frames, so in principle it can be done. The question is performance, i.e. at which framerate can we produce the solutions. It definitely will work in a frameing mode.

Short status report: the algorithm that extracts the diffraction pattern and fits the Bahtinov lines to it, thereby measuring the offset of the center line is implemented in my local copy of EKOS.
Since I had to switch to GSL for the numerical libraries, I am working some convergence issues. Next will be work on the graphics (plotting the lines corresponding to the found solution).

I'll post pictures as soon as I have something presentable.

Cheers, Sebastian

Just a thought; as an interim feature, could it be possible to select an overlay (akin to cross hairs and guidelines) and centre a Bahtinov mask directly on the selected star in the acquisition images. The selected star will still be auto focused as usual but the viewer will see the Bahtinov mask pattern results as the focus becomes more accurate. We are talking about a pretty bright star for Bahtinov therefore the pattern can be proportionate to the corresponding HFR .

Note: should this be an existing feature on other applications I was truly not aware. I only use Ekos.

Hi.
It would be totally awesome if you could give us the real time streaming view at 5x and 10x, as in APT.

Just thought I share my experience with Jasem's autofocus tool, using a very simple home-built autofocuser with a timed motor (not a stepper motor) and Shoestring Astronomy FCUSB as the driver. I focused using Jasem's tool and then checked using a Bahtinov mask. Here is the result:



Couldn't me more perfect, I would say.

PLEASE, Jasem, do NOT give up on the autofocuser. It is (almost) PERFECT as is!
