I've been playing around with open phd, trying to add a function to name the stars that the guidescope is showing.
Here's what I'm doing:
- using PHD's "Auto select star" algorithm to find the brightest stars in the image.
- work out the distance and angle between the brightest stars.
- Loading the Tycho2 catalog, and moving the stars based on their yearly movement.
- Finding the best match in the catalog for the identified angles and distances.
Here are the results:
(Orion SSAG screen shots used through the phd simulator camera).
I still have a few problems. The two red stars in the first image are critical - the distance and angle of these two are used as a reference for all other stars. If an image has a really bright star, sometimes these two end up on the one star. I'd like to add a method to manually remove and add "tagged" stars.
If there's a planet, or other solar object tagged as a star, it would mess things up too.
I still need to add a settings window to set the searched field of view, error tolerances, number of stars, threads used for calculation, etc. Once this is done, I might try incorporating it back into the open phd project.
What would be nice is a Stellarium plugin, so when you click on a star in PHD, it selects it in Stellarium.
Anyway, let me know what you think...
