Hi Trevor,

Stitching images of smaller areas of the Moon together like this is a great way to create spectacular mosaics, although, sadly, they can easily become too large to upload to your page on this website without a lot of compression.

May I suggest you try using a piece of freeware called imerge for this: you can find it here: http://www.softpedia<dot>com/get/Multimedia/Graphic/Graphic-Others/iMerge.shtml or just google for it. I've used it for this purpose and it has several very nice features including simple drag-and-click to merge two images, and "feathering" between adjacent images to eliminate the obvious joins and edges that you refer to. I think if you give it a try you'll be pleased with the results.

Good luck!

Chris 

Thanks for the suggestion Chris. It's always good to have recommendations from users! I will give Imerge a try.

I picked up MS ICE from Nik Szymanek's (sp?) bookazine about astrophotography. I think it works quite well but I think I might try making the composite from the initial stacks rather that from stacks fiddled a bit in Lightroom.

Best wishes.

Trevor
