M13 again. This is a stack of 135 frames (from 10s to 30s in length) and much gentler processing in Maxim DL and PS.
I am pleased with this – there is much to criticise, but much to enjoy too. Stars are consistently visible down to mag 16.9 – very close to the theoretical predictions for my scope and camera. This is equivalent to a 17 inch (430mm) telescope used visually (though it would also have more resolving power too)

  2. Thanks for trying to subscribe. I know nothing about Android or Feedr, but the feed is working fine. Just check that you have entered the feed url correctly:
    http://curtisfamily.org.uk/feed/
    Note that there is no “www” in the url.
