24/10/13: Imaging Update

October 24, 2013

Although I was generally pleased with the bicolour image of the Crescent Nebula, it just highlights how much exposure you need when working with narrowband filters. I've recently acquired an SII filter with the intention of creating images using the Hubble Palette (SII:Ha:OIII). Over the last couple of weeks I've managed three hours' worth of SII data. The weather hasn't exactly been friendly in this regard! Nevertheless, then next step will be to add some OIII data. I also plan to experiment with slightly longer subframes. I routinely image with 10 minute subs, but it's certainly worth trying 20 minute ones to see how it goes. This should improve the signal to noise ratio and the smoothness of the image. More to follow when I manage the OIII data!
