Well it seemed like a great idea at the time....LOL
Here is my 64 panel mosaic of Orion using a RASA-8 and ASI2600MC!

Full, technical details are on the Astrobin link but, in brief, it was actually relatively straightforward to acquire the data (and only about 20 hours of subs) but subsequently quite an ordeal - and a massive learning curve - to process the final image.
I have had a hard time getting this from the multi-gigabyte original down to a size that seemed respectable even for Astrobin so please ignore the thumbnail presented here and head straight to that 'still not very high res actually' version on Astrobin.
I'm still not entirely sure that I really achieved what I intended here - from a distance, the mosaic looks very dark and lacking in stars (and actually not very interesting). It is only really when you start to zoom in that you get to appreciate some of the richness of the entire field. There are also some rather nice unexpected gems in there e.g. the tiny Abell-13 planetary nebula (you will have to hunt to find it:))
