Re: [guide-user] RE: CCD Field

osastro Jun 20, 2014

Hello Bill,

thankyou for your Help.

Now it runs great !

I have now made some kombination with cameras and focal lenght into my CCD contoll and now i can see, where 
i must slew my Teleskopes to have the Objekt on the two diffrent field of view.


Best Regards
Oliver

Hi Oliver,

   It should work like this...

> My first camera have 5472 x 3648 Pixel and 6.58 my Pixel.

   Which would make the whole camera 36005 x 24003 microns.

> The Second camera have  3362  x 2504 Pixel and 5,4 my Pixel.

   Which would make this camera,  which we are pretending is the "guider" camera,
13521.6 x 18154.8 microns.  Thus,  it is 0.5042 times as wide as the first
camera,  and 0.56333 times as high.

   So the line I get to be added to 'ccds.nam' _and_ 'ccds.nad' is

Canon Eos 6D/G2-8300             Cmos         6.58     6.58 5472  3648    6 0,0,0.5042,0.56333,3362,2504

   With a couple of warnings.  You'll see that after the 3648-pixel height,
I gave this camera (okay,  two cameras) an ID number of 6.  You used 1,  which
is already in use by the 35-mm film frame.

   Also,  after doing the math to compute the relative sizes of the two cameras,
I re-read your message and realized that there are two different telescopes
involved,  presumably with two different focal lengths.  So those values of
0.5042 and 0.56333 will have to be multiplied by the ratio of the focal lengths.
