Radial Blur For Solar Eclipse Post-Processing

I'm doing some post-processning on some images I took of the total eclipse.  I need to apply a radial blur to a copy of a layer.  However,  the moon/sun are not exactly center in my images.  I've read that you have to shift your image so the radial blur can work properly.  However when I do that and then apply the blur, I get an odd warping on the right and lower portion of the empty canvas (due to the shift to center the image).  See image below.  How can I prevent this from happening?

Thanks

Well, I don't 'think you can select your canvas.  By performing a Select All, that selects the entire image on your canvas.  You should be able to turn your rulers on and use Percentage.  Make a horizontal and vertical ruler line at 50% for each.  Then do the select all on the image and move it to be centered on the ruler marks.  Only then you can perform a proper Radial Blur.

Hope the helps.

I think I resolved my problem.  When I centered the image, I failed to select the full image prior to applying the Radial Blur.

    Would you mind spelling out for me what you mean by "selecting the whole image?"  I have the same problem.  It seems like my whole image is selected, including the blank canvas.  If I crop the image, it goes back to off-center.  Move it back to center, and I get the canvas edges again.  Very frustrated.  Thanks in advance.
