One problem with astrotracer is that it won’t work at anything less than 10 seconds, which is way too long. The elongation has to do with those points being so small that any vibration at all show up. You have to tighten everything down very solid, every adjustment on the tripod tight, you need to use a 2 second delay on the shutter release AND you need to use a cable release or remote trigger. > > Jupiter/Saturn convergence. 3 moons visible. | Flickr > <https://www.flickr.com/photos/wisselstroom/50741056587/in/datetaken-public/> > > Alan C > -- > 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. > -- Larry Colen [email protected] -- 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.
