Image Date and Time

How can I get the Image List Browser to display Date/Time?  This column is always blank for my images.  The FITS headers for my images have the standard DATE-OBS key word.

Sander Berents

That's odd. Observatory does handle the DATE-OBS keyword, so maybe it fails to parse the format used in your images. Could you please share one of your images using Dropbox with support@codeobsession.com so I can take a look and have it fixed in 1.2.2?

I am not a regular user of DropBox but have uploaded an image and shared it with support@codeobsession.com

File name:  DeltaCep180129023939.FITS .  Please let me know if this works.

The FITS header looks normal to me both within Observatory and within other software on my computer.

Sander Berents

Thanks, I received the file. It looks normal to me too, but it turns out the date parser in Observatory is missing one variant (it handles many). It will be fixed in the next maintenance update.

Thanks.

But more about my troublesome MicroObservatory FITS headers.  LATITUDE and LONGITUD are included in these headers.  Latitude is displayed in the inspector, longitude is not displayed.  Is this something that can be fixed?

Sander Berents

Observatory recognizes several variations of the longitude FITS keyword, but indeed not LONGITUD. Similar for the camera temperature, Observatory recognizes several, but not the CAMTEMP one used in this FITS file. I'll go through the whole header and add support for any that are missing. It will get fixed in the Spotlight plugin as well.

More FITS header madness.

I just noticed that BITPIX = 16 for my MicroObservatory FITS images.  Unfortunately, it is obvious that these images are really only 12 bit images.  The obviously overexposed image regions have values of 4095.  This is an issue I will bring to the attention of the MicroObservatory people.  However, will this be a problem for Observatory?

Sander Berents

Observatory's internal saturation handling is initialized using the FITS DATAMAX keyword. Your file doesn't have any though. It isn't exposed in the UI yet for manually setting it. I'll make a note to add it.

Observatory 1.2.3 is out. It adds support for the FITS headers generated by MicroObservatory. Please select the images that are missing this information in your library and choose "Image ▸ Reset Attributes..." to have it reload it.
