Stellarium 0.10.6.1 Toucam settings?

[coldlegs (Stephen)]

I was about to enter my toucam in the stellarium oculars as a sensor when I noticed a "chip height' box. Haven't got a clue what that would be for a toucam or if it makes much difference. Does anyone have the settings for a toucam used in a prime focus fashion? Do you have to also select some kind of lens? Not sure what to do here but I'm sure someone out there has figured it out. Please let me know.
Thanks

Hi Stephen

Firstly what version of stellarium are you using. The CCD sensor was only perfected with build 4856 and was completly changed again with build 4858.

As far as I can guess the Toucam will have the common pixel size of 5.2microns and the chip will be nominally 1316 x 987 pixels so the chip size will be approx 7.4mm by 5.06mm

These values can be entered for a start and then see how the view compares with a full frame shot

These are the values I entered in my ocular.ini which works for the early and late plugin versions

3\name=toucam
3\resolutionX=1316
3\resolutionY=987
3\chip_width=7.4
3\chip_height=5.06
3\pixel_width=5.2
3\pixel_height=5.2

The actual FOV will depend on the focal length of you telescope

How do I tell what the build is?? Is it in a config file or something?
I wish my toucam had all the pixels you think it has but had to settle for
3\name=toucam
3\resolutionX=640
3\resolutionY=480
3\chip_width=4.6
3\chip_height=3.97
3\pixel_width=5.6
3\pixel_height=5.6
This seems to work but I wish I could get rid of the oculars. I just want to see the camera view without a lens in front of it. Is there some kind of "do nothing" lens that will let me see just the "prime focus" view?

Hi Stephen
There were a few versions of the Toucam I used the one that had 1.3 megapixels as an example because I had no other information. The settings you have shown look good for the 640 x 480 pixel version.

You can't tell the version of stellarium unless you are compiling it yourself and you did not say whether you had the release version or one you had compiled yourself and I don't think the release version had support for a CCD.

If you have used the patch I made
http://sarcasmogerdes.dyndns.org/ste...-patch0106.zip

you can get the build 4856 version of the ocular module. This has a number of key bindings to select oculars, sensors and telescopes. They are:

toggle_oculars=Ctrl+O
toggle_config_dialog=Alt+O
toggle_telrad=Ctrl+B
next_ocular=Ctrl+]
prev_ocular=Ctrl+[
next_ccd=Shift+Ctrl+]
prev_ccd=Shift+Ctrl+[
next_telescope=Shift+]
prev_telescope=Shift+[
toggle_crosshair=Alt+C
ccd_rotation_angle_minor_decrement= Ctrl+8
ccd_rotation_angle_minor_increment= Ctrl+9
ccd_rotation_angle_major_decrement= Shift+8
ccd_rotation_angle_major_increment= Shift+9
ccd_rotation_angle_reset=m

These keys will allow you to select how you display the view. Just toggle through them till you have the arrangement you want. If you select a telescope and a sensor it will display what the sensor sees at prime focus.

My next patch will have the new ocular module
http://sarcasmogerdes.dyndns.org/ste...-patch0107.zip

which at the moment is very complicated to use with popup menus that are not linked to the configuration button. If you get it make sure you read the readme file first. This version also has a copy of my ocular.ini file

Thanks for the patch Barry. Keep up the good work.
