I just click no for an empty screen and the next image comes up.

I do a quick pattern check of new versus reference to check it's the same starfield. Most clicks are no

What's the "Bad - black/white" stuff about in the tutorial? All the images look black and white to me ;D

The source in the subtracted image should just be white - if it's made up of some pattern of black and white dots then it's clear something has gone wrong with the automated routine...

Perhaps one out of every 30 to 40 images.

So do we just ignore the Blanks or list them for possible removal?

Wow this is really cool stuff, but my bed time is rapidly approaching...if it's going to be around for the rest of the week, then I'll give it a try, after reading the tutorial and following up on the comments here, so I know what I'm doing.

Hi Chris.

As promised, veni...vidi...; however, no vici.  ::)

I'll come back to it and see what I can get.

A word on the tutorial, though, you mention that one is to look at the "reference"; then look at the "new". Is the "reference" always in the middle? Why? It seems that our eyes would go from image #2, to image #1; then to image #3. This seems counter-intuitive to a proper process. Perhaps this is intentional, but I fail to understand.

It's not clear how to answer this question:  "Is the candidate centered in its host galaxy?"

As the host galaxy doesn't show in the right-hand window are we supposed to look at the cross-hairs in the Reference window and see if they are off-centre?

Well, I think I've got the swing of it!
Oh let me just a moment stay
where time is not and angels play the paeans of the galaxies;
then speed the stardust on its flight
to change dread darkness into light, cold chaos into ecstasy!
