A quick RGB set of data from late Nov - taken while waiting for Orion to clear a tree! 45:40:40 all in 5 min subs, ST2000XM through FLT110 at ~f5.6, all on the Titan. Reduction and processing in PI, with final small tweak in PS. Couple of interesting objects here aside from the cluster itself (which is 4100ly away itself). OW Aur is the deep red star in the lower left (varying between mag 12.3 and 13.6) - this is another example of a carbon star. Also visible (just!) is "Holoea" - this is part of a bipolar outflow from a Young Stellar Object, and can just be seen in the image below. More details from the paper linked up from my page here: https://www.chromosphere.co.uk/2017/02/09/m36-carbon-star-ow-aur-holoea/ Thanks for looking!
I grabbed the frames for this image on the night of the 5th Nov as a quick target after having got a lot more data on the Bubble. ST2000XM, with a WO FLT110 at f5.7 - R:G:B = 35:35:35 (5min subs) at 1x1. Processed in Pixinsight - it's tricky to hold the colour in the stars for these images - but really like the colour of the deep red carbon star V358 Aur (colour index ~1.57, V mag 12.something) in the lower portion of the image. Thanks for looking!
