Bhatinov feature?

[Doug Z.]

First, I have to say I'm a total fan-boy for BYEos! It is the gold standard for image capture programs.

Thank you, Guylain!

 

Now a question:

How do you use the Bhatinov feature in the Premium edition? I don't see any reference to it in the User Guide (V.2) I have read. Does it work in conjunction with a Bhatinov Mask (which I have) or...?

 

Regards,

Thank you, Rick, for the detailed explanation. I will give it a try next imaging session.

Great question and response! 

 

I was wondering about this as I was simply using the live view to focus with my Bahtinov without using the BYE feature.  I especially like the "green circle" when you are within the preset tolerance.  Is this tolerance user adjustable?

 

Yes, it's configurable... in Settings dialog.

Does the mask have to be oriented in certain direction? Jerry

No, any direction will do.

Doug,

 

While I don't typically use a Bahtinov mask, let me try to explain how you might use it.

 

Get close to focus with the view finder, LCD LiveView screen and/or BYE's LiveView screen. 

 

Make sure that you have a bright star in the field-of-view.

 

Put the mask on the scope, over the objective.

 

Activate LiveView in Frame & Focus and select Bahtinov, instead of FWHM or HFD, as the focus metric.  This will cause BYE/BYN to superimpose lines over the spikes that are caused by the mask.

 

Activate Star HD mode and select one of the Bahtinov presets, or choose your own values for the Star HD controls, to enhance the display of the star and spikes.

 

Adjust the focuser to move the center spike on each side (and BYE's superimposed line) up or down. 

 

A green circle will be drawn around the star when the spikes are centered to within the tolerance as specified by the Bahtinov Range value on the Settings screen.

 

As I said, I don't use a mask for focusing, so if I have given you any incorrect information I hope someone will correct me.
