News in the 2009 MAY 15 version


Second Data Base

This version introduces an important new. Beside working with the usual data base, you can now use a Second Data Base for big images solving.

This Second Data Base:
-- allows solving images with a bigger field, about some degrees,
-- no image-orientation (image angle) dependency,
-- searches the full sky,
-- very fast,

This working mode, is adecuate for altazimutal mounts.

So the main question now is : " Which database is the best for me ?"

The answer depends on the image size and the mount type:
-case A - little images, say less than 2 degrees AND equatorial mount: use the First Data Base.
-case B - little images, say less than 2 degrees AND altazimutal mount: usualy Elbrus is not able to solve.
-case C - big images, say between 2 and 10 degrees AND equatorial mount: use the Second Data Base
-case D - big images, say between 2 and 10 degrees AND altazimutal mount: use the Second Data Base

If you want to use this Second Data Base, you must download from the files-section of this group at the "Second Data Base" folder, the two files

estDEC_ID1x1gbin.zip and
tri2g02bin.zip, and unzip them.

Then put them in the folder defined in the menu "Others / Edit parameters" "Distances DB" line . They are needed only when analysing the big images, as said before.

To switch from a database to the other, go to the menu "Others / Edit parameters", and push the radio buttons at the 'Data Base' line.


Help-advices for guidance to the target

Once the image is solved, two labels appear with advices on how to move the mount to reach the target. The coordinates of the "target" are the coordinates in the "Coordinates" menu.
For a correct computation of these advices, you must introduce the observatory data in the "Others / Edit parameters" menu.

Un-zoomed images

Images can be now reduced to 50 % or 25 % size. Go to the menu "Show" and choose the displayed size.

Note: The pixel size in the "Others / Edit parametres" menu is the size of the pixels in the analysed image. They have nothig to do with the displayed image size.
