Interactive 2D and 3D room-scale or object FOV simulator for cameras, telescopes, lenses, etc.
- Replaced FOV formula with higher accuracy version for wide angle lenses v0.80 - First public release
Enter the focal length of your telescope or lens to use for calculating the Field Of View (FOV) and the resolution arc-second per pixel. If you are using Canon/Nikon lens, APT will read the current lens focal length after each exposure and will update this value automatically.
11 sie 2013 · Expanded and cleaned-up equipment database with over 1,200 different telescopes/cameras/eyepieces/binoculars. Show an image of any part of the sky (search using the simbad database, or by coordinates) Images now draggable in eyepiece (and binoculars) mode. Images can be rotated and flipped.
9 kwi 2017 · I checked the simulation for 82° FOV and 119X magnification, for your 85mm f/7 scope. It gives the image below: the 82°FOV is 1231 pixels wide, while Saturn is 28 pixels wide (including rings). This means that Saturn apparent size after magnification is 1.865°. Before magnification, it is 0.01567°, i.e. 56''.
27 maj 2022 · Last night I ran across an astronomy field of view calculator site that shows what size a target would be, using different scopes, cameras, etc.. 12 Dimensional String, has anyone used it? How accurate is it? Why have I not seen this before?
