[bird (Anthony Wesley)]

I picked the best run from the 16th and reprocessed it more carefully. There are 750 frames each of red,green,blue and I processed them through registax in batches of 250 to get 3 masters for each colour. These were recombined in Astra Image (reducing noise) and captions added in the Gimp.

I really like the batch-processing approach because it gives me the ability to do some "real" noise reduction right at the end of the processing chain, so I can push some of the intermediate steps a bit harder.

10" f/6 newt @ 6000mm FL
fire-i mono camera @ 25fps.
1.3x resampled image

With sufficient averted imagination the GRS is still *just* visible on the south-west limb (bottom left).

edit: original image replaced with a slightly better one, from a few minutes later, so GRS probably not visible any more.
