Originally from ticket #27914.
I have been trying my hand at creating a horizons of my local area for loading into SkySafari.
I have stitched the panorama together and saved as a ping. Unfortunately the system says that my image does not contain a valid panorama. Admittedly my panorama is a bit rough, but at this time I just want to establish the steps needed to create a successful horizon. I have some questions regarding your help pages in SkySafari.
Near the top of the notes it says the image should be 4096x2048, but a bit further down it says the image should be 2048x1024. Which is the correct dimensions?
The help notes say the image should be a 32 bit RGBA png file. If I set the colour depth to 32bit in Photoshop, then there is no way to save a .png file. Please can you give me some explanation here. At the moment I can only create a 16 bit image using Photoshop CC 2015
I created a layer mask to delete the unwanted sky in my panorama in Photoshop. Does this create the alpha layer that is needed in SkySafari? If not would you mind describing the steps for me?

Would you mind sharing your panorama with me. Attach it to your reply. I will review it.

Thanks for getting back to me so quickly.
I have worked out what I need to do to get my panorama to work correctly.
The image needs to be an 8 bit PNG and not a 32 bit PNG as stated in the notes.
The image needs to be 4096x2048
In Photoshop just delete the sky to reveal the chequered background to create the transparency required for the night sky in SkySafari. You can delete the unwanted pixels using any method you like.
Might be useful if the help file was updated, especially the 8 bit vs 32 bit?
