Astrophotography filters: How narrow is too narrow
Saturday, June 29, 2024 by Jim Thompson
For many years now I have been promoting the idea that for emission nebulae, whether you have light pollution (LP) or not, the narrower your filter’s pass bands are, the better. Time and again my test results have demonstrated this relationship to be true; that object contrast and signal-to-noise-ratio (SNR) increase as the pass band width decreases. Recently howe...

How amateur telescope makers defended America
Monday, June 24, 2024 by Richard Harris

NGC5005 and 5033 astrophoto from the TS-Optics 10 inch ONTC
Tuesday, June 11, 2024 by Jon Main
I have been interested in imaging NGC5005 for several months, ever since I saw the Hubble image of this galaxy. The Hubble image showed bright blue regions that I interpreted as active star formation. In hindsight, it should have been obvious that the Hubble team took some 'creative liberties' with the data and made the Ha regions blue. I stuck with the project ...
