Thanks, everyone. I'm getting better solutions on photos from days ago using your suggestions, especially narrowing the +/- tolerance. Rain and clouds for the next few days but I'm looking forward to trying it with the telescope again. Overall: AA8 is marvelous and I've really enjoyed processing ima...

Iver,

Yes, I did save - you can see that button is greyed out in the picture above.

Thanks, Dunmuro. I have had little luck with AA8 controlling the mount or plate solving off-line with no telescope hooked up. Things are just... weird. For instance, it did successfully plate solve for an image of M51 if I told it to look for M51. On the same image if I give the center search region...

Re: AA8 SP1: In another post I asked about installing a catalog for plate solving. Bill kindly explained how to install GaiaComp, which I did. I not longer get an error message when loading the star atlas. But plate solving nearly never works. I've been banging my head against this for months. I too...

Folks, I not having much luck with plate solving. Googling it appears I need to download the UCAC4 catalog. The URL in AA8's manual (ftp://cdsarc.u-strasbg.fr/pub/cats/I/322A/UCAC4) gives a baffling list of directories and filenames. What do I download? They are all tarballs and gz's. Another link f...

Thanks, Fabio. I'll give that a shot.

Thanks, Bill. To do that supposes one knows what background one wants to reject. One cool feature of AA8 is the graph of sky background produced by tools:preprocessing. I use that to get an idea of where to set the limit. But, alas, to get that one is slaved to hitting the "skip" button lots of time...

Folks, When I'm preprocessing images it's common to have clouds drown out many of them. But when AA8 gives an "error" as it can't align things, I have to manually press "skip." What that means is if I have hundreds of images I have to babysit the computer for a long time to hit "skip" when an image ...

Cancel this question: I see this is a result of adding the darks and flats. Without them the report gives the same background as the raw images.

Using AA8 SP1, 64 bits. Been trying to make sense of the reports from stacking images. After stacking, using "sigma + Sum" as the algorithm to combine images under tools:processing, the report shows the "Background" for each image and the range. However, the "statistics" window for an individual ima...

Thanks, Bernd!

Folks,

I'm using a purchased version of AA8 and can't seem to find the GAIA catalog. Some forum responses suggest it's at users\<name>\documents but I don't see it there. Any idea where I can get this?

Thanks,
Jack
