NGC 604 in M33, Reprise (October 2016)

Here is NGC 604 again with more data, now with 40x600" instead of just 12x600".  Everything else is the same about the setup: it is the CFF 290 Classical Cassegrain operating at f/7.93 (A-P CCDT67 Telecompressor).  The camera is the SXVF-H9 through an Astronomik CLS filter.  The larger data set gives a better signal-to-noise ratio, and the dimmer parts of the image are brighter, with more definition.  The image reveals the mottled, star-spotted arms of a galaxy.
