How Focal Ratio Affects Your Astro Images - Sky

- Why Focal Ratio Matters. The tradeoff between aperture and focal length is reflected in the instruments focal ratio. A 200-mm (8-inch) telescope with a 2,000-mm focal length has a focal ratio of f/10. By contrast a 200-mm …

Astrophotography, Pixel by Pixel: Part 2 - Focal Ratio Effects
- https://cloudbreakoptics.com/blogs/news/astrophotography-pixel-by-pixel-part-2
- While aperture cannot be completely ignored in astrophotography, often what we care about more is the focal ratio of the telescope. The focal ratio is a unitless number, and can be found by dividing the focal length of the telescope by the aperture. For example, if a telescope had 80mm of aperture and a focal length of 500mm, then the focal ratio of the scope would be …
Astrophotography and F ratio - Cloudy Nights

- Here's the way I think about it.. Astronomers think in aperture(diameter) and focal length or focal ratio. Photographers (not me) think in terms of focal ratio and focal length. Consider two telescopes: A 100mm aperture with a 1000mm focal length = F/10 A photographer thinks of this as 1000mm F/10 lens.

- Fast f/4 to f/5 focal ratios are generally best for lower power wide field observing and deep space photography. Slow f/11 to f/15 focal ratios are usually better suited to higher power lunar, planetary, and binary star observing and high power photography. Medium f/6 to f/10 focal ratios work well with either.
What Does Focal Ratio Mean In Telescopes? The Simple …

- While not as important for casual viewing, the focal ratio can have a profound impact on astrophotography. Getting good shots of different objects is going to require different focal ratios. If you want to take a picture of a binary star system in high detail, you are going to need a high focal ratio.

- This focal length is goo for recording the many star fields and dusty regions in the Milky way. Figure 2. 200 mm f/2.8 lens, 1.3x crop camera, 25.4 minutes of exposure at a dark site.
In Astrophotography, Bigger Is Not Always Better! - Sky

- Long focal-length, deep-sky astrophotography (starting around 2,000 mm) is best done from outer space, or when you're well along the challenging learning curve. ... Tiny pixels work better with short focal lengths and fast focal ratios. I always recommend starting with monochrome imaging, without color filters, as color processing is a whole ...
Calculators for Astrophotography
- https://www.astropix.com/html/astrophotography/astrophotography-calculators.html
- Calculators already have sample data in them. Some are examples from my telescope, a C11 SCT with 279.4 mm of aperture and 2,794 mm focal length at f/10. Highlight the numbers already entered in the boxes and delete them and enter your own. For large numbers, do not use commas. Formulae used for these calculators.
What the “f/ratio” Means in Telescope Lingo
- https://telescopeschool.com/what-the-f-ratio-means-in-telescope-talk/
- For astrophotography, however, what’s more important is the f/ratio rather than the aperture. In cameras, the f/ratio is what determines how much light falls onto each of its pixels. We would want to maximize this because the objects we are imaging are usually very comparatively dim.
