Stacking images in the Milky Way is never much fun. I typically have to restack with various frames removed to give the target asteroid an uninvolved image....

Has anyone on this list used WCSTools? I gather it doesn't allow a cubic fit which if correct is crazy. Astrometrica seems to outperform it dramatically,...

I am wanting to do some astrometry of images from my SXV-H9C but these appear to be not analyzable by Astrometrica. Is there a straight-forward way? I don't...
I keep having this annoying issue when stacking images. It doesn't happen on all my stacks and sometimes theres just one or two images that is throwing things...
... With the current version, there is not. However, if you send me a description of the file file format that is used for storing color images, as well as a...
... I tried your images, and increased the "Alignment Area" in the program settings to 512 pixels, and the images were aligned OK. The original value was 200...
Ok...great....I hope this solves it for me because you can imagine how annoying it was to have 18 images that looked fine and have trouble getting any 3 of...
Thanks Herb, I just got home and tried this and it worked...except that for one of my stack it was still failing until I increased it to 700x700. This has...
Hola, ... I don't think so. If the alignment fails, then it fails entirely. And you won't see an almost perfectly aligned image with one or more stars just a...
... Hmm, if you input a wrong motion though which is not really the right motion for the time of the stack, then you have a non-symmetric problem and you will...
Actually that's exactly what I've seen before....one or two stars just slightly off. Hopefully with the larger alignment setting I won't be seeing that again....

Shouldn't be possible to remove the 5 images limit when solving a batch of images?, when I shoot, say 60 images, of an asteroid trying to find out the light...
... Of course, I understand your point. Astrometrica was designed and implemented with astrometry in mind, and for that, five images is usually more than...

Herbert, that's a great step forward. Thank you very much. To select motion and center coordinates separately is a great help at large FOVs with many objects...
