Spiral galaxy Messier 100

Composite based on five images taken with FORS1 on Kueyen (VLT) by Dominique Naef, Eric Depagne and Chris Lidman (ESO). The images were taken through different filters: U, V, R, I, and a narrow-band filter centred on the H-alpha line. The exposure time is 60 seconds in the V, R and I filters, 3 minutes in the U-band and 5 minutes in the H-alpha filter. The field of view is 6.8 x 5.1 arcmin2. North is up and East is to the left. The final processing was done by Kristina Boneva, Haennes Heyer and Henri Boffin (ESO).
