Calculating the setup values voor pulseguiding (TheSkyX) with a SBIG ST-I guide kit and Widefield lens.

Hello all,

I’m gearing up to completely drop all the known opensource astro applications and instead using TheSkyX Pro for controlling a relative easy Widefield setup on a AVX mount.

My question is simple, how can I calculate the Autoguide (pulse guide) Setup parameters when using a:

1. Canon Mark 7D Mark II with a pixelsize of 4,11 µm
2. Zeiss 135mm lens at an effective focal length of 131mm
3. an SBIG ST-I autoguider with a pixel size of 7,4  µm
4. an SBIG ST-I guide kit lens with a focal length of 100mm.

Given the setup above I want to calculate:

     a. Minimum move (in seconds)
     b. Maximum move (in seconds)

and determine the Calibration times of the X-Relay and Y-Relay before I go out.

Thanks in advance! 

Best Marc

Attachment: calculations thus far:

Image Scale =  (206 X PixelSize (um))/Focal Length (mm)

Guider Scale =  15,244 arcs/px
Imager Scale =  6,463 arcs/px 

Total Allowable Errror  =  Imager Scale X % (total guiding error) /100

% guiding error    80 %
TAE   5,170 arcs/px

TAE (pixels) =  TAE arcs/px / Guiderscale arcs/px 

Tae (pixels) =  0,339 px

Minimum Move =  TAE / 2

Minimum Move =  0,170 px (or ? how many seconds?)

Maximum Move = Minimum Move X 2

Maximum Move =  11,79318735 px or (? how many seconds?)
