General Discussion / Any available video tutorials ?
« Last post by Jean-Claude on April 18, 2019, 12:28:17 PM »
It is true that the Observatory manual is detailed (136 pages) but I must say that I'm struggling since two days to find out how I could START using Observatory. And what for.
OK I know : to classify my photos.
But then I'm confused with the concepts of libraries and albums.
Some videos could explain this easily.
On the page there are a few very short explanatory videos but I couldn't watch them. This was probably due to the low bandwidth (200 KB/s) that I have at home.
I've been looking for more extensive video tutorials on the net and I couldn't find any.
Could you give some links ? Thanks
Hi Jean-Claude,

There's no need to copy the application or anything from ~/Library. Just install it from the App Store on both machines. In the App Store application on your 2nd Mac, using the same Apple ID you used for the purchase on your 1st Mac, click on Store ▸ View My Account and then click the download button. That way it also gets automatically updated when needed on your 2nd Mac.

To share the images & Observatory libraries, put them both on that external SSD. I have never tried this myself, but as long as you always save and close the library on one computer before opening it on the other it should work. It is likely that sandbox permissions will get in the way though, making it necessary for you to help Observatory to locate the source folders when you switch between the computers. That is currently not recursive (the fix for that is targeted for the next release).

Let me know if you run into issues.

My images are stored on an external SSD that I can connect to my desktop or my laptop.
Let's say that I manipulated my images with Observatory on my desktop and I would like to continue on my laptop.
What files should I copy from my desktop to my laptop to get the same configuration (after having connected the external SSD) ?
I found two files in my library :
~/Library/Application Scripts/com.codeobsession.Observatory
but their transfer doesn't preserve the configuration.
Shall I also copy the app itself ?

Hi Sander,

Yes, I tried "upload whole image".  The camera is a Nikon D7000 DLSR and the images are Fine JPEG colour.  I'll try a Raw image and see how that goes. I'll also set the catalog to Tycho.
I'm hunting for comets (have been since 1980 - closest call was in 2007 just arc minutes from Terry Lovejoy's second comet :-[)

I didn't. I doubt right now it will make a big difference though because the current bottlenecks in the image processing pipeline are disk I/O and some parts that are still running on the CPU. Observatory uses OpenCL internally and I think you may start seeing a difference when it gets support for Metal, because that is also when I intend to remove some of the current inefficiencies that occur when applying multiple adjustments to an image (a left-over from the time one could apply the adjustments in any order).

Hi Richard,

When you tried blind plate solving, did you also try it with the option "Upload whole image"? Is there any particular reason why you are using a JPEG for this? You may have more luck with FITS or a RAW image format because JPEG has such limited dynamic range and the star detector may reject the stars, thinking they are over-exposed or even hot pixels. Is this a monochrome or RGB image? An image with such large FOV shouldn't require UCAC4. Observatory's built-in Tycho-2 catalog should suffice. If nothing works, then please share one of your images using Dropbox with, so I can take a closer look.

I have been trying to plate solve - both blind and with local UCAC4 for jpeg images but no luck thus far.  I have varied every input possible but still not luck - I get the error message every time.  The images are large - 4928 x 3264 pixels - taken with Hyperstar and representing approximately 1.75 x 1.15 degrees.  Pixel size is 4.78 x 4.78. I have reduced the frame size as suggested in the error message but no effect.

The image is correctly oriented - it is mirrored to compensate for the telescope.  I am not aware of any place to enter a position angle - is this needed?

I would very much appreciate any help as this is what I purchased the Observatory software for.

Thanks for you help.

Has anyone tried running Observatory using an eGPU? If so, does it make a noticeable difference in image/stack processing time?


General Discussion / Re: new to Observatory -- can't import images?

I am able to import images just fine. Please excuse my newbie error and frustration.

The key I had not understood was that I *first* needed to add each source folder *before* I could import images.

Thank you VERY much for responding, especially over the weekend.

Do they have the .xisf extension? Will they import if you drop a folder with .xisf files onto the Observatory icon in the Dock? If not, then please share one with using Dropbox for example, so I can investigate the issue. I have no trouble importing xisf files myself.
