  1. How's going people? Long time since last post due to bright Swedish summer nights, gear-tuning and automation fiddling, but now I'm up & running again. I'm starting off the dark season with one of my favorite targets inside the cygnus loop, NGC 6992, east veil nebula. The subs where acquired during three moonlit nights, all subs unguided. (shooting other targets too, so subs are shot when the target is in the highest position in the sky, thanks to ACP automation) I've only used two filters for this image, Ha & O3 (both 5nm). I mixed the color close to Ha/O3/O3 as R/G/B , with slight different weights in G & B, to reach a more blue tone rather than cyan. Both Ha & O3 was used as luminance-data. I also created a "natural" star-color mix of the layers, with Ha / Ha+O3 / O3 as R/G/B and adjusted filterweights until I had a natural mix of yellow & blue (go Sweden!) stars, which was later applied as color-data with a star-mask on top of the image. The Subs (unguided): Ha : 19 x 600s / 190 minutes O3 : 12 x 600s / 120 minutes Total time: 310 minutes / 5.2 hours The Scope: Orion Optics AG12 Aperture: 12" Focal lenght: 1140mm Focal ratio: f/3.8 Imaging scale: 0.98" / pixel together with my QSI 583 The Mount: 10 Micron GM 2000 HPS All subs unguided The Camera: QSI 583 wsg (with 8-position filterwheel upgrade) Filters: Astrodon Click image for full resolution: It's been so much fun to see this object in the high resolution my setup produces, so many faint formations of nebulosity I've never seen before. I also recommend to have a peek at the following link, it's crazy how different the same object can look, imaged through different wavelengths: Click here to see the difference between the Ha & O3 at my homepage, with a "mouse-over" function that switches between the two Thanks a lot for watching Best Regards Jonas Grinde http://www.grinderphoto.se
