How did you get 39 seconds with astrotracer? I thought it did increments of 10 seconds. First of all, one of the challenges of astrotracer is that if the geometry of the image isn’t uniform, then you’ll get motion bluring in some parts of the image, like you seem to have gotten in the corners. It’s hard to tell on my screen, but it seems that you may not have quite nailed focus. What I tend to do is to find something bright at infinity, like jupiter, zoom in on live view manually focus, then ideally tape the focus ring down with blue tape. You’ve got the weird color going on in the sky, I think that’s pollution showing up close to the horizon. > > https://flic.kr/p/2oKr3QE > > enjoy > bill > -- > %(real_name)s Pentax-Discuss Mail List > To unsubscribe send an email to pdml-le...@pdml.net > to UNSUBSCRIBE from the PDML, please visit the link directly above and follow > the directions. > -- Larry Colen l...@red4est.com sent from ret13est -- %(real_name)s Pentax-Discuss Mail List To unsubscribe send an email to pdml-le...@pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
