    Integration time (running total):
    * L 14 X 60s (14m)
    * R 12 X 60s (12m)
    * G 12 X 60s (12m)
    * B 12 X 60s (12m)
    * Total: 50m

Notes

Messier 10 is a very low target from 52°N and one which I had never considered photographing. The poor visibility is made worse by the poor southern horizon here. However, the short integration time has produced a remarkably good image of this beautiful globular cluster, helped by the stable sky this evening. This was really an experiment to…

Notes

Imaged in May, the Splinter Galaxy showed no signs of the tidal tail which probably needs darker skies than I have here in Coventry to be photographically visible.

Notes

Continuing what has been an incredible galaxy season weather-wise with another version of a large galaxy. Again I decided to reimage this in monochrome with additional weighting for the Hydrogen Alpha channel to highlight the star-forming regions.

Possibly the most beautiful galaxy visible in the Northern hemisphere. I decided to reimage this in monochrome with additional weighting for the Hydrogen Alpha channel to highlight the star-forming regions.
