David's Astronomy Tools

[iceman]

David Lloyd-Jones has written some astronomy tools over the years, mainly for his own benefit, but has now made them available for the IceInSpace community.

You can download them from the IceInSpace Files (http://www.iceinspace.com.au/files.html) section, and the tools are:

Bahatinov Mask Guide – A simple rotatable and resizable reticle for centring the middle spike within the outer two X spikes of the Bahtinov mask pattern.

Dave's Crosshairs – General purpose crosshairs. The double crosshairs can be lengthened, moved and rotated as required. Both the separation between the hairs and the thickness of the hairs can be adjusted. A selection of hair colours is allowed.

Night Vision Saver – An adjustable intensity rubilith (red and other colours) simulation that can be used to cover all or part of the computer screen to preserve night vision.

Telescope Circles – A collimation aid for centring the secondary mirror's silhouette within the primary mirror's reflection when viewing a defocussed star. The positions of the collimation screws can be displayed and allowance is made for any distortion of the image due to incompatibility of the camera's output format with the image capturing device's format. An accompanying Help file is provided.


Thanks to David for contributing his resources to IceInSpace.

Thanks Mike,
I love the idea of the red screen / rubylith simulator but I was trying to click on the underlying windows with the red screen maximized and that didn't work as the focus is retained on the night vision saver when you click in the red area.
you'd want the red screen on all the time.

The on Top button does keep it on top and you can use the alt-tab to switch windows and use the keyboard to work in other apps, but not with the mouse.
any way around this?

Cheers

The Baht mask guide and telescope circles are brilliant.
