Hi All,
I am hoping someone can help me work out what my FOV is on my AP set up, I have run the maths but don't believe the result I am getting.
I have the following set up on the main imaging scope:
William Optics Megrez 90
http://www.williamoptics.com/telesco...rez90_spec.php F6.2 (90mm * 558 MM long)
William Optics Field Flattener 4
http://www.williamoptics.com/accesso...4_features.php (0.75 - 0.8 * Power)
Canon EOS 600D (no point linking this one
)
So my main issue is how to work out what the field of view becomes once I add the Flattener as it is a 0.75 - .08 * power and adds lenght to the image path. Also I have read by some that this is not actually a ~0.75 * power and more like a 1.18 * Power????
If any one is able to assist I would be most grateful as I want to plan the targets I can image (with good detail) and fill most of the field of view.
Thanks in advance for your help.
Cheers
Anthony
