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:
- Canon Mark 7D Mark II with a pixelsize of 4,11 µm
- Zeiss 135mm lens at an effective focal length of 131mm
- an SBIG ST-I autoguider with a pixel size of 7,4 µm
- 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?)
