Fighting Dragons In Hawker
This is 6.2 hours of data taken at Hawker, South Australia about 2 weeks apart, 4.7 hours of Astronomik 12nm Ha filter taken during a near full moon and the remainder taken between cloud breaks on a near new moon with no filter. I have previously posted UHC filter data used as colour with Ha as luminance, I think this is a little better. I haven't yet tried to incorporate the UHC filter data with the RGB as previously that wasn't a great result, but may try later. I took about 4 hours of Optolong L-Pro filter from metro Adelaide to add to this but I'm not impressed with what I got, and it was ruined by sensor dust that moved before I got flats dammit! Anyway, the main nebula name here is NGC6188, The Fighting Dragons in Ara, which isn't well known in the northern hemisphere. This just isn't as colourful or bright as some other targets, I'm not totally happy with this but realistically may not improve on it much. Calibration, registration, gradient removal, combining RGB and Ha as luminance and some work on star colour, saturation in Astro Pixel Processor, which is really good for this deep sky stuff, but not without issues. Final tweaking in Photoshop (which is much easier to edit photos in). Nikon D810A, Astronomik Ha filter, 600mm focal length f/4, Celestron CGEM II EQ mount, ZWO guide camera, APT camera control. RGB shots 10 minutes at ISO200, Ha shots were 10 minutes at ISO800.
