ghost of Jupiter

While waiting for Saturn to get enough elevation to image the Titan transit, I tried for the Ghost of Jupiter with the Astro 40D on the 14" at f6.3 .

I found that 20 seconds was the longest I could go without burning out the centre of the planetary nebula.

Focus is a bit off, due to the lack of time I could spend on it. This is a stack of 4 x 20 seconds.
