IC1318 in Cygnus

•August 23, 2011 • Leave a Comment

With a clear sky & Cygnus high in the evening sky I focussed my attention on IC1318. For some time now I have been using the Astronomik h-alpha filter, mainly due to the fact that the moon is almost always present when I have clear skies.

One of the main issues I have using the CLS filter is harsh gradients & high green channel. Gradients can be removed to some extent by miens of flats  and post processing techniques.

Here is a tighter crop from previous image, it may require a little extra post processing to bring out the darker nebulosity.

The Summer Triangle

•May 30, 2010 • Leave a Comment

With summer pretty much at my door step the summer triangle is the first thing I think of in terms of astrophotography. Over the winter there have been some additions to my kit bag, an EOS 7D (review on low noise is in Draft), a Leica/Leitz Apo-Telyt 180mm f3.4 & a Nikon 50mm f1.2 AIs.  I hope to get some good images – especially from the Leitz Apo-Telyt it was originally built for the US Navy as a reconnaissance telephoto lens.

Back to the summer triangle.
