Limit attempts at Star Alignment?

[JamieInCLT]

Is there any way to limit the number of tries that StarAlignment makes to Align an image?

Each "try" seems to take longer than the last, and I don't know if it will ever give up (right now it is on try 21).

The pictures looked ok in the blink, but since I don't completely know what I am doing yet I am sure that I missed something.

I would like to be able to just tell it to stop after 10 cycles or something.  I looked at the docs for StarAlignment, but I don't really understand most of it

Hi,

SA should not fail to register your images. If it does, then that's most likely because you're trying to register dissimilar images, too noisy images, or perhaps because SA doesn't find any stars for some reason. We'd need to take a look at them to say something more. 

To disable SA's automatic probing routine, open the Star Matching section of SA and set Maximum stars to a reasonable nonzero value such as 1000 or 2000 stars. Anyway, SA will probably fail to register your images, irrespective of this setting.

I have had this problem with wide fields. StarAlignment will continue (almost) forever, i.e. >24h until I reboot the system. StarAlignment was working very slowly because of the memory consumption (memory thrashing).  Killing PI was not possible because TaskManager would not come up (presumably due to the memory shortage). This was on a 4 GB Win7 x64 system. I guess this is what Jamie observes.
