Bi Colour Eta
Eta Carina in Narrowband Bi Colour. 7 x 5mins of Ha mapped to red, 14x5mins of OIII mapped to blue and green. I was aiming to really emphasis the oxygen in this image which has succeeded I think. Not a lot of integration time but a bright target doesn't really need it. Have been wanting to do an image of Eta at a "tighter" image scale so very happy overall. Not a APOD but I like it
Equipment info:
Scope: Celestron Edge HD 8"
Mount: Orion Atlas EQ/AZ
Focuser: Moonlight Lightcrawler
Camera: ZWO ASI1600 MM Cool
Guiding: ZWO ASI290MM MinI and ZWO off axis guider, PHD 2
Acquisition: SGP
Processed entirely in Pixinsight. Had a couple of runs at this tonight. Final run only took about 40 mins so I think I am getting the hang of processing these. Finding with this camera I can pretty much not bother with noise reduction. Others may disagree but not sure it is worth it as it tends to make the image softer and could not see any benefits.
