Hi all,

I've been working on a few more web-based calculator tools recently, and would be interested in your thoughts and suggestions for them.

First is a quite simple one, it just displays some info on the position of the Moon on a given date, and displays a simulated image of it:
http://www.12dstring.me.uk/moonphase.htm

The next one is viewing information for the planets. It displays position, phase, magnitude and size information, as well as images of the planets - scaled to their relative sizes as viewed from Earth. Furthermore, the phases of Mercury, Venus and Mars are displayed, as well as the ring angle of Saturn.
Also clicking on the name of the planet brings up a window with the current position and distance as well as opposition/conjunction/max elongation dates, and some fixed orbital information.
http://www.12dstring.me.uk/planetsizes.php

Lastly, and the main one (incorperating aspects of the previous two) is a Field of view calculator and simulator. There's two versions, one for imaging, and one for eyepieces/visual views. Upon selecting a telescope and camera/eyepiece (or entering your own specs) some various info is calculated on the setup such as magnification, field of view... etc.
You can also select a particular object (such as a planet, Messier object - the list is expanding) and the image is displayed below to show the relative field of view if an image was taken/viewed with an eyepiece with that setup.
The planets and Moon change dynamically with the date selected, phases are shown, sizes change, and the moons of Jupiter are correctly positioned.

I'd be very interested to hear people's thoughts on them, if you have any suggestions for features, as well as bugs or display problems.

Thanks,

Hi Dave,

Wow, you mean M42 will look like that in the images I take with my DSI on my 102SLT? :lol:

Seriously, the FOV calculator is pretty kool. It's great to have the visual display of what will actually be captured. Seems like it will be very handy.

PS: Since I am using a DSI (trying, learning,... whatever) with M42 camera lenses (35-70mm zoom, 150mm, 300mm, etc) on it, some of your pics aren't large enough, you need Hubble Spacetele pics of about 16,000x12,000 (widefield) pixels :shock:

Hi Dave,

I am finding the FoV calculator very useful. I can quickly see what my DSI is going to see (at least FoV wise). And it's taught me something already, namely that the object size in Stellarium is sometimes wrong.

It is also useful to anyone buying eyepieces, they can enter the details and see what view the eyepiece/barlow/telescope/object combination will provide.

Super little program...

Hi,

pretty cool :) Just for comparison, have a look on our FOV Simulator :)
