Last night after Neowise sank into the haze I spent some time playing with astrolandscapes on Mary's Peak (west of Corvallis).
I did an experiment with the sigma 35/1.4 on the K-3ii aimed at an interesting part of the milky way, astrotracer at 10 seconds, f/1.4, slow shutter NR (darkfield subtraction), bracketed ISO 400-12800, plus I tried a couple of HDRs in LR6. Nominal exposure was at ISO6400, the rest were compensated to match, other than that everything was processed the same. Using the fluidr page to make it easier to compare: https://www.fluidr.com/photos/ellarsee/sets/72157715235343631 My takeaways from this are: close up shots of the milkyway without any other sky for context just look messy The sensor is impressively ISO invariant, at least when it comes to astro photography I really need to get some good stacking software that runs on my macs -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
