About this image

Poor seeing conditions, 4 hours outside at -2C, frost everywhere! Only best 5% of image frames selected from 12x3000 frame videos, half with uv / IR half with Pro-planet filter. Images captured as videos with SharpCap, then centred and quality selected with PIPP, then aligned and stacked with AutoStakkert and treated with Astrosurface (including wavelets and deconvolution), and then derotated and final image created using Winjupos. Conditions really not good with high jet stream and bad layers.
