Is this a normal amount of noise for a 6400 iso, 1" sub?

You can also upload your image to astrometry.net and get this

But @almcl's overlay is quite cool. How did you do this?

Awesome! Thanks for the cool map, did you make it or use a tool? Seems like a cool thing to be able to use if it's like a website.

You're welcome!

Took a screen grab from  Stellarium (useful, free planetarium program, in case you don't already have it) having guessed your location as somewhere on South Island, then overlaid your image with a bit of transparency and shrunk it to fit. 

There is a Website, astrometry.net , that will do much the same thing, although it may need a slightly better signal to noise ratio image to plate solve.

 With canon cameras some users are finding darks add more noise, I don't take darks but I like flat darks as well as flats (same as flats just add lens cap).

I have found this on occasion with the 6D

flat, dark and bias

Hi

60d, so lose dark frames of any type. Instead simply subtract a constant offset of 2048. ISO 800 throughout.

Cheers and HTH.

The reported "best" ISO for the Canon 60D is 800, have a look here.

What's the reason that some older models beat out newer ones in ISO capability? I notice some of the newer Rebel models are sitting in the 400-800 range, while the older ones are rated at 1600.
