Hi all.
Under the waxing Moon I tried some narrowband imaging with the EOS Ra. 7 x 20 minute subs at ISO 800. Really impressed with the low thermal noise of the 30 MP sensor. To be fair I'm only utilizing the red pixels on it so not really 30 MP. 10 inch f5.6 Newtonian hand guided in pretty good seeing. Calibrated in IRIS, blue and green channels discarded. Finished in Photoshop
