Here's a successful result from a light polluted southern hemisphere site. Obviously the alpha and lambda circles are meaningless but the pole position is correct.

The Tk image viewer doesn't show the long thin image so I've shown it with a third party viewer. I've also duplicated your circles in CdC for reference.

None of the stars in the original frame (40mm lens on a 70D) were visible with the naked eye. This looks like a very useful tool. Thanks.

Does it work with a local astrometry.net engine installation (or will it in the future) ?

One of the joys of this hobby is that getting out to dark skies also means no inter-web.

I have some real numbers as we have some travel planned and needed to know how heavy my mount options were. I didn't want the wifes bag to be over the luggage limit.

These are with the counterweight shaft but no counterweights.

EQ5 (non-goto) head = 5.5kg, tripod = 5.3kg

CG5-GT head = 6.4kg, tripod = 7.3kg

Super Polaris head (RA drive only) = 4.2kg, Wooden tripod = 4.3kg

Set of Al legs off EQ3 type mount = 2.6kg
