Nice job Patrick, your stitching is great no seams!
Thanks. In case you or anyone is interested here's what it looked like with all of the panels laid out before being joined: http://users.wirelessbeehive.com/~paw/temp/m45-02.jpg Turns out shooting them was made quite easy via TheSky's "Mosaic" feature. It even allows overlap between the images. Even joining them all together wasn't that big a bother. Just blow the whole thing un to 200% and then slide them together one pixel at a time. The hard part was getting all of the backgrounds to be the same shade of grey so I didn't have 16 different colored blocks.
16 shots and still not all of it, that's a small FoV.
Yeah, even with the focal reducer each panel is only 18x26 arc minutes. This time I binned 3x3. If I do it again I think I'll try less binning and slightly longer exposures.
Of course I've only ever been able to image M-45 through a pair of Binos, not impressive but was a fun experiment.
Fun! Do you still gave the picture? If so you should post it. Interesting. The first picture of that sort I even took was through one side of a 20x50 binocular using an old Speed Graphic sheet film camera. Still got the negative somewhere. patrick
