plate solve outside images failure

Post by jacobson » 19 Apr 2026, 03:41

I use AA9 with two different ASI cameras both with APC chips. I can plate solve all of your sample images and sometimes with my previous processed images. I am puzzled why I can not plate solve an old image of the E. Veil. I follow the prompts to a" T " stating image is at 20:45 +30.42, fl at 780mm with a chip 23mm wide.
I search at 3 degrees. pick 5 stars and flip this every which way only to fail. HOw can I send you a jpg of this image so you can tell me what I am doing wrong. thank you. I have enjoyed AA9 save this annoying issue. cjacobson
the original image is in a Tiff format and too large for my emailer.
thanks

Hi, post a JPG image to the forum, even resized if it's too big.
To attach an image, click the tab "Image and attachments" below the editor.

The M104 image has a FOV of about 1 degrees, so entering: 60 +- 20% arcminutes will solve it, the exact FOV will be 65.9

The N6995 image has a FOV of about 1.5 degrees, so entering: 90 +- 20% will solve it, the exact FOV will be 95.6

When the FOV is unknown set the tolerance to +- 70%, then try 1 degrees, 2 degrees, etc.
