I had a go at processing your file. I took thew qhy8 zip and then stacked in DSS. Took the autosave file into PS CS3 and just did levels and curves until it was almost right. The followed this procedure to remove vignetting
(

Hope the JPEG is OK
I then downloaded the stack from the canon but there was no colour in it. I processed the same in PS as previous image and the second jpeg is the canon result.
You really need a lightbox
