Announcement: New Applications
We are excited to announce the launch of our new applications! We're opening up early access to our new applications for searching, downloading, and submitting photometric observations. You can now access these applications through these links:
We ask for your feedback in order to help us improve these applications. Please send feedback for the applications above to feedback@aavso.org. Note: please avoid duplicating submissions across the two submit applications.
I assume you had an issue with the speed of the queue that prompted this question?
VPhot uses Pinpoint that needs an image scale so that it can plate-solve the images. Obviously, there is some uncertainty in this value. Pinpoint uses the defined image scale reported in your telescope settings and some error band in its calculation. IOW, it does not fail unless the image scale is significantly different from that value.
Therefore, a small amount of error does not slow the plate-solving process. If the image scale of your image is much different than the reported telescope setting, then VPhot tries three catalogs for 20 seconds each before failing/skipping to the next image. My own image scale is very stable. Do you think some images sent to VPhot are not?

IMHO, astrometry.net is not faster.
