Input from Karl-Ludwig Bath, 7.3.2020:

When shooting with the full resolution, Tangra shows only a section of the image (the upper left corner). Especially on small screens like on Laptops. As a result, you have to search for the ROI quite laboriously, even repeating it for checking purposes. Therefore the image in Tangra should be scalable (setting a zoom factor) to show the full picture on the screen. This problem does not only occur with ROI, but also with full images, where you have to search then for the stars.

• On the light curve form, also show the value from the FITS header(s) used for the current frame
• In the LC file record the selected options for FITS time reference i.e. the names of the FITS header cards, the time reference (start/mid/end) and the exposure units.

This should play nicely with the existing 'Shrink to fit' and 'Scroll' display modes.

The first click doesn't get registered. A second click is requried to select the object.

When you make recordings during occultation observations and set a resolution image given by your camera, especially with binning=2, please remember: the final resolution will be appear in the Tangra window with the final value, i.e. the rectangle will be 2x smaller with binning=2.
However, with such setting you obtain better quality of starfield and a faster transmission (higher fps) to your hard drive.
Tell something about you experience, please!

When converting from ADV files, both should include the same header cards and pixel format.

I am interested if somebody does obtain a permanent dropping of video frames?
Unfortunately, I do. No dropped frames occur for low image resolution only, for instance 640x480 px and with binning 2 (a little bit too small image) using SharpCap software and "ser" file format
Using factory ZWO ASI software called ASICAP even gives worse results but SharpCap is a ZWO dedicated software, too. The lost frames usually causes obvious serious difficulties when using Tangra.
By the way, no other software apart SharpCap was running.

Use online Gaia data

Should be somewhere in the settings. Things to include may be:

Camera, AquisitionDelay, TimeReferenceOffset

Also make sure that Camera is remembered when choosing it for analogue videos and instrumental delays.

While there is a progress bar when loading/saving the .lc file, it seems that there is a quite long interval after the Light Curve reduction is completed and before the Light Curve is displayed where there is no progress bar at all.

• Overlay a text stating "THIS IS A STACKED VIEW"
• Gradual transparency increase from green rect borders inwards for another 10 or so pixels

Should allow 2x2, 3x3 and 4x4 binning implemented at TangraCore level for better performance.

May be store this information in the .lc file for processed light curves?

This can be made available for FITS and ADV files
