Loving the tool. It would be great if you could add an eye dropper feature so that if I alter text or numbers that are over a color background I can erase the copy fill in the area with the original background color and then revise the copy over the background fill

It's awesome! Love the fact that I can make changes to PDF's! Love the ease of this application. I'm still wondering if I can transition information to Excel spdsheet.

Just getting use to this program
Just getting use to this program. Was having a hard time finding my form that I needed but I think I have it figured out now.

needed a PDF filler software easy to use
easy to fill out lots of PDF forms without hassle
Easy to use. Can save forms for future use. Does not require any extra learning. Intuitive format makes easy for anyone to use.
Cost was a bit much, but decided the year membership was the best savings deal.
Have used it multiple times already in the first few months so I am glad I did not do a month to month membership.

We no longer had use for product as we are a small Not for Profit Organisation and they canceled our subscription that was automatically renewed and refunded the $'a that was charged. This happened without any issues and thanks to pdFiller for their understanding

I am not computer techy
I am not computer techy - and I have been able to figure this out to do what we need. I am sure there are features that I have not figured out yet - but I stay very busy @ work so doing a webinar would be tricky to schedule.

How do you increase the resolution of a telescope?
Another way to increase the resolution is to connect telescopes together to make an interferometer. Radio waves from an object reach each telescope in the interferometer at slightly different times, so the waves are out of sync with one another.
How do you determine the resolution of a telescope?
Since 1 radian = 57.3 degrees, and 1 degree = 3600 arc seconds, the resolution is 0.000000069 radians x (57.3 degrees/radian) x (3600 arc seconds/1 degree) = 0.014 arc seconds. One thousand millisecond = 1 arc seconds, so the resolution is 0.014 arc second x (1000 millisecond / arc second) = 14 milliseconds.
How do you calculate angular resolution?
The manipulated formula should appear as the following A = arc sin [1.220(W ÷ D)]. Use your calculator to do the math to find out what the angular resolution (A) is equal to. The units of the wavelength and the diameter cancel, so the answer is expressed in radians.
Which Telescope has the best resolution?
The Magellan telescope can theoretically resolve images much sharper than Hubble can because its mirror is 21-feet in diameter, as compared to Hubble's 8-foot mirror.
Why is the practical resolution so different from the theoretical resolution of a telescope?
So what does it mean? Firstly, resolution is inversely proportional to the size of the primary mirror. The larger the diameter of the mirror, the smaller the value of, the theoretical resolution. A large telescope therefore theoretically can resolve more detail than a small telescope at a given wavelength.
What is limit of resolution of telescope?
The limit of resolution (or resolving power) is a measure of the ability of the objective lens to separate in the image adjacent details that are present in the object. It is the distance between two points in the object that are just resolved in the image.
What is resolution limit?
The limit of resolution (or resolving power) is a measure of the ability of the objective lens to separate in the image adjacent details that are present in the object. It is the distance between two points in the object that are just resolved in the image. ... Thus, an optical system cannot form a perfect image of a point.
What is the limit of resolution of a microscope?
Lateral resolution in an ideal light microscope is limited to around 200 nm, whereas axial resolution is around 500 nm (for examples of resolution limits, please see below).
What is meant by the resolution of a telescope?
The angular resolving power (or resolution) of a telescope is the smallest angle between close objects that can be seen clearly to be separate. Resolution is limited by the wave nature of light. For a telescope having an objective lens or mirror with diameter D and
What is Rayleigh limit of resolution?
In that case, the angular resolution of an optical system can be estimated (from the diameter of the aperture and the wavelength of the light) by the Rayleigh criterion defined by Lord Rayleigh: two point sources are regarded as just resolved when the principal diffraction maximum of one image coincides with the first ...
