Narrow band imaging refers to imaging using filters that only let through a very narrow range of the light spectrum, often 0.07nm or less. They effectively block all other light frequencies. The spectral width of these filters therefore blocks out a lot of light pollution – light from streetlights in towns and cities that reflects […]Read More What is narrow band imaging?
Last Sunday I had a rare opening in the UK’s rather wet summer weather so I set up my new kit and sequenced a night on NGC 6888; the Crescent Nebula. We are just past the summer solstice here in the UK and, given my rather northerly latitude of over 51N, it isn’t dark until […]Read More Attempt at NGC 6888 (Crescent Nebula)
There are a number of cost effective imaging software packages available and, in my opinion, Sharpcap is one of the best. The software is regularly updated and Robin, the developer, is continually adding new features to widen the scope (no pun intended) of the package. Sharpcap is primarily an imaging solution that allows you to […]Read More Sharpcap
