Looks great. I got the polarie recently but haven't had a chance to test it. Would be interested in learning what settings you've tried and the results. From what I've heard, the best results are from taking multiple exposures and stacking them with dark slides. I've also seen that their are some really funky things astrophotographers will do like taking some pics with high iso and some with low.
Also, did you have any issues blending the two exposures? Or is it just simple layer masks...?
Thanks Jeremy.
I started with rather conservative settings. My initial settings were ISO 640, F5.6 and exposure of 140 seconds. I got much better milky way shots with F2.8, ISO 800 and exposure time of 140 seconds.
What strikes me the most is the relatively lack of noise. I did not do any noise reduction for the sky in the image above. My ISO 6400 images before the tracker had good details but lots of noise. They were only good for smaller prints ( at least for my taste).
The problem with multiple exposures and stacking is the foreground. It is very time consuming to stack when the foreground is moving(tracked image)
I usually take two images. One for the sky and another for the foreground without tracking but using the same settings. This way my sky in the foreground image has the same tonality of the tracked image sky. This makes the blending much easier.
I did a very simple mask to blend the two images.
