If you do not receive your order within the respective timeframe, please contact us as soon as possible. Please note that the delivery time indicated above is approximate. Inks: eco-friendly latex technology inks (made in Germany)Ĭertificates: Greenguard Children & Schools and UL ECOLOGOįREE WORLDWIDE SHIPPING for all wallpapersĪll deliveries have tracking numbers, provided via email to customers the same day as the order is dispatched. When you compare our wallpapers with those of other manufacturers, please pay close attention to their density (it is usually not indicated, so you get thin wallpapers, while ours are heavy vinyl 300 gsm, damage- and scratch-resistant, can be cleaned by a wet cloth, and they will serve over 10 years without fading and losing their amazing vividness and colors) Material features: Waterproof, Moisture-Proof, Mold-Proof, Smoke-Proof, Soundproof, Sound-Absorbing, Heat Insulating Type of wallpaper: Heavy vinyl wallpaper (not self-adhesive, need glue) Couple of false starts there.Material: Paper-backed heavy vinyl wallcovering 300 gsm/m2 (made in Netherlands) I spent a while figuring out how to do the stretch without blowing out the galaxies. The only place where I had to go back and redo a couple of times was 8 & 9. Seems complicated when I write it down, but it all flows quite naturally. PixelMath to combine the two images using the max(starless, star_mask) function to choose the brighter of the two pixels at each position.ArcsinhStretch on the star mask to stretch and boost colour.HistogramTransformation to get a black point I was happy with.GeneralizedHyperbolicStretch to reach a final stretch I was happy with.Then imported mask back into Pixinsight and applied to the nebula image. As the outer layers of the galaxies were the same brightness as parts of the nebula, I imported the range mask into a paint program, and painted out any nebula and the halo of the bright star 44-Serpens so I would only protect the galaxies. RangeSelection to create a mask that would protect the galaxies in the field.MaskedStretch to see what I am looking at for further stretches.EZ-Denoise gives about the same result to my eyes, but NoiseExterminator is faster I am trialling NoiseExterminator at the moment. NoiseExterminator on the nebula image to reduce colour noise in the background.Starnet2 to remove stars and create a star mask.SpectrophotometricColorCalibration to adjust colour balance using a preview of part of the image I felt was genuine sky as the background reference.BlurExterminator to control stars - I was using a 300sec exposure so stars got a bit big.DynamicBackgroundExtraction to get rid of gradients.If I remember, the processing went something like this:īasic calibration and stacking using WBPP This is one-shot-colour so we are RGB all the way through. However, even here only about half the subs were usable due to high thin cloud (that plays merry hell with faint nebulae).Īll processing was done in Pixinsight. The data is good as I am using a remote observatory in the mountains of southern Spain ( rather than my cloudy, murky backyard in North Wales.
