NGC 6188 in moonlight 7Nm HA with the Ra

[tornado33]

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
Full size version here.

Thanks all. Yep it's great. Had to get a fast memory card to do the 4k stuff. 30x live view makes for accurate focus. Only bummer is my pc and 7th generation 16 gb ram laptop take ages to process 4k video and converting the 30 megapixel images. Houghy has kindly lent me his portable Polarie mount so I might be able to get some dark sky widefields soon :)
