Clay's Kochab Clock

[mballak]

Is it possible to use the hash marks on the reticle in the drift align mode to polar align using Clay's Kochab Clock?  My understanding is you need to move 1 degree off polaris in the direction of Kochab to be aligned (in the north).  Is it possible to calibrate the hash marks based on focal length and the size of the camera sensor?  I think it may be but I'm not quite smart enough to figure out the math.  Any thoughts?

Thanks,

One possible solution is to use Astrotortilla to determine the FOV and then 'guesstimate' the distance (43 arcmin) towards the NCP.  Then the only thing would be to set the angle to Kochab on the crosshairs.

 

There isn't feedback from AT to BYE, is there?  If there is, couldn't you get the FOV and then set the tick marks?  Just a shot in the dark (cloudy skies here).

Aaron,

 

The only communication between AT and BYE/BYN is to request an image.  The only communication from BYE/BYN to AT is the path of the image.

 

If you are using AT, then it seems like you could use its Polar Alignment function.

Good one... but I think we are in the same boat... I would not necessarily know where to start

This would seem to be more complicated than it first appears, as Guylain would need to account for Focal Length, Sensor Size, Reduction / Magnification Effect of any Additional Optics, etc.

 

You'd be much better off looking to use BYE's Drift Alignment support...

Yeah thats kinda what I thought too but wanted to ask anyway.
