Took me a bit of figuring as to why they look so different. Rowland's and mine are flipped vertically with respect to each other, maybe Rowland has a diagonal in the imaging train? Mine is all straight through with a refractor.
Mine looses a bit in the compression too, even the full size jpg version looks a lot crisper let alone the uncompressed tif. I have never really liked the 200kb file size thing for that reason, I have not got the knack of getting the files under that limit without them loosing a lot. I will pop it on Astrobin when I get home and link that. I did not have a chance to do it this morning, this is literally from data that I was still shooting at 10:30 last night. As things turned out I should have left it run as I could have got about another 30 subs before the roof of the house or clouds stopped it.
