About this image

It's a long time since I've done any planetary imaging but this very favourable opposition of Mars is too tempting to resist. I've used RegiStax before but had no experience with AutoStakkert.

My C11 is well collimated but seeing isn't good in a suburban garden 5 miles from Leeds, surrounded by radiating rooftops, and in this case it was between Ant. III and IV. Even so, I'm enjoying getting a series of images of Mars and can always hope for moments of Ant. II seeing.
