Ok after fixing all the damage Yosemite did to my programs I have got it working in both nova and local modes in OS X 10.10.

I added the following code after line 311:

    else:        # OSX local        #        exe = '/usr/local/Cellar/astrometry.net/0.44/bin/solve-field '        if not self.havescale:            # first rough estimate of scale            options = opt1 + "--crpix-center -b /usr/local/Cellar/astrometry.net/0.44/etc/astrometry4100.cfg "            cmd = exe + options + filename             print '___________________________________________________________'            print cmd             os.system(cmd)            self.update_scale(hint)            print ("estimated scale: %.3f" % self.scale)            print '___________________________________________________________'        else:            # fine tune with finer indices            print "known scale ", self.scale, " used: ", self.help_scale.get()            options = opt1 + "-b /usr/local/Cellar/astrometry.net/0.44/etc/astrometry4200.cfg "            if self.help_scale.get() == 1:                up_lim = self.scale*1.1                lo_lim = self.scale*0.9                options = options + "-u app -L "+("%.2f" % lo_lim)+" -H "+ ("%.2f" % up_lim) + " "            cmd = exe + options + filename             print cmd             os.system(cmd)            self.update_scale(hint)

Local solves of the test files take about 6 seconds, this is similar to what I get solving my images so I am happy with that

When I get some clear skies I will try this out for real.

Well I had some good progress but messed it all up by installing Yosemite. It seems to have killed my Python and homebrew installs

Gonna take a while to fix that.

I think the install location would be the same as Linux if I built astrometry from scratch but I used homebrew so it goes into Cellar.

I added an else after the windows os elif and put my install location there.

Once I get Python working again I should be able to test it properly.

Ok I'll take a look, I imagine it will be very similar to Linux.

Will it be possible to use a local astrometry install via the solve-field command?

I imagine that a few user inputs would be required to keep it quick, the downsampling level, scale high and scale low values.

It should solve very quickly indeed if you use --dec 85 --radius 5 since you know it is going to be looking near polaris.

My solves only take a few seconds when I run them like this.

This would offer a complete standalone solution to all platforms, obviously astrotortilla is windows only at the moment.

Yep I have Python installed.

If you can provide the files I'll give it a whirl and see what happens.

This is quite an interesting project, I'd be interested in testing it, do you have a OS X version of the installer?

Won't it look like that anyway if you are telling PI to create an RGB image?

I would have thought you would need to image something distinctly red, green or blue and check all the pixels expose.

I don't know about your specific chip but I did notice when I took mine out to remove the IR filter that there are no exposed wires like there are on other chips. I would guess that there will be a lot of variety in chip designs, the problem is that means you can't even be sure that the bayer matrix will actually come off without damaging the sensor unless someone else has managed it on the same sensor.

I believe it has a larger buffer so should have less dropped frames even on USB 2, whether this is the case in reality I don't know as I don't have one.

You didn't update the firmware did you? Your only supposed to do that if the camera isn't working properly, like if you try to use it on a Mac. You can roll back the firmware with the same program that updates it if you did.

It sounds like the bottleneck is somewhere else, either your hard disk write speed or the exposure you have set.

I normally have it at 60-70% USB traffic.

Glad you got it sorted, I had a problem with --objs at first too, I had -objs and it didn't like that for some reason.

It does seem odd, I would try convert one of your subs to jpg an try it in simulate mode.

What image format are you using? It doesn't recognise my cameras raw files so I have to save as jpg for plate solving.

Well with 6 elements even if you know the correct order there are 64 different combinations just depending which way each is facing. If you don't know the correct order then there are 46080 combinations!

And that's assuming the spacers are all the same, if they aren't your looking at 5529600 combinations.

If you test a combination every five minutes for 12 hours a day every day it would take over 105 years to try them all.

I think I'd rather send it back to the manufacturer
