Displary of sensors in occular plug in

This isn't a defect, but a feature request.

Just as you would rotate the camera on the telescope to get the bounding box to cover what you want in the image, I'd like to add the ability to rotate the CCD censor area in plug in. This is what I'll implement.

OK Tim

Being able to rotate the rectangle will be OK when implimented. However I belong to a large very active photography group and the default position for cameras is "landscape" with north centred up on equatorial aligned mounts. Yes cameras are sometimes rotated for specialised framing but not regularly.

Hi

I have checked through a number of exposure frames of our 1000D fitted to various telescopes as well as the same camera running with a range of camera lenses.

When the camera is run piggy back on a tracking telescope, the standard camera orientation is as one would normally use for general use ie landscape where the x axis is related to the horizon. The camera has the same orientation when used on a refractor or Schmidt Cassagrain. On an equatorial mounted telescope the north/south axis will be parallel to the short sides of the rectangle.

When the camera is mounted on a newtonian telescope, equatorially mounted and tracking. The standard position appears to be with the camera longest axis, x axis, parallel to the optical tube. This will produce a photo with the north/south axis parallel to the long sides of the rectangle.

As the actual mount of the camera is a matter of personal choice it is therefore necessary to be able to rotate the frame at least 90 degrees but preferably to any position.

From my measurements against the photos I have the size of the rectangle shown at build 4851 is correct for my photos from a given telescope. The changes to the CCD dimensions with build 4853 have given a rectangle of the wrong size.

Barry

 There is an error in the reference to build 4851 on the above post last paragraph. The size of the rectangle is incorrect and varies according to the ocular FOV. I thought it was OK because I was using a psuedo eyepiece to increase the FOV.

4853 is OK for the height dimension and fits to my photos but the width is about 30% too much.

Barry

Ya, I was using the height & width of the screen to determine the CCD
bounding box, when it should have been the narrower of the two. The latest
commit has that corrected. I also changed the text label on-screen to show
the degrees covered by the CCD.

I'll work on rotation next.

O.K., rotation has been implemented. The hot keys are not editable via the GUI as I'll wait for the app-wide editing scheme. The default hotkeys (which can be edited in the config file for the plugin) are:
Shift-m : reset rotation
Ctrl-8: decrement rotation angle by 1 degree
Ctrl-9: increment rotation angle by 1 degree
Shift-8: decrement rotation angle by 10 degree
Shift-9: increment rotation angle by 10 degree

Hi Tim

I tried your latest fix to the oculars sensor rotation. Looks great size and window spot on. Major rotation perfect. However I could not see any change for the minor rotation (ratation ?). Maybe a typo?

I've fixed the type.

If the Ctrl+[8|9] does not do anything for you, that would be due to a key binding conflict with something else. It's really getting ridicules trying to manage key bindings. it's not just that all the keys are used, it's that keys that should be relinquished when a plugin is loaded are not doing so.

Anyway.

hi Tim

Yes key bindings is the problem Ctrl 8 and 9 are used by the telescope module. If this is not loaded ctrl 8 and 9 work with the ocular module

Hi Tim

I got around the problem by editing telescopecontrol\src\telescopecontrolglobals.hpp
Line 29
const int SLOT_COUNT = 9;
to
const int SLOT_COUNT = 7;

This removed the selection of telescopes 9 and 10 which were of doubtful use and freed up ctrl 8 and 9 for the oculars OK

Not being a programmer I don't know what other effects this causes but the telescope module still works OK except I can only select 8 telescopes now. Bogdan might be agreeable to make this change standard.

Hi Tim

I have uploaded stellarium-0.11.0-win32.exe to my web site. It may take a few minutes to download as the max speed from the server is only about 1Mb/s

http://barry.sarcasmogerdes.com/stellarium/uploads/stellarium-0.11.0-win32.exe

should get it for you. It did for me.
