Two Milky Ways

Image Description:

I have updated my large mosaic of the Milky Way with the high resolution imaging I did in 2021. The upper image is taken through H-alpha, SII and OIII filters and the lower one through HaRGB. All the major nebulosity is now taken at a focal length of 530mm. This gives the image very crisp detail when viewed as a whole. Other images around the major nebulosity were taken at focal lengths of 85mm and 14mm. This mosaic has a total of 216 panels and over 2200 hours of imaging time. It uses data taken over the last 3 years which is why in the HaRGB image Jupiter (which looks like a very bright star) is above Sagittarius and in the SHO image which I took 12 months later it is below. That's how far it moved in a year.

Equipment Used Telescope Canon 35mm L Series Lens, Sigma 85mm Lens, Takahashi TOA-130/FSQ 106 (Detail for the Nebulae) Camera STL-11000M/STXL-11002M (Detail of the Nebulae) and SBIG STF-8300 and Canon 6D DSLR for the Widefield

216 image Mosaic with ~2268 hours of imaging through RGB. H-alpha, SII and OIII filters.
