michaelmorris Posted February 1, 2009 Share Posted February 1, 2009 Here is a mosaic of two picture taken last night (31/1/09). Each AVI was 2000 frames. These were MAP processed in Registax 4 (best 500 frames) then merged and post-processed in Photoshop. Because this was right on the terminator the dynamic range was just a bit too much for my Toucam. Oh to have the dynamic range provided by the 12-bit images produced by a Lumenera camera! Link to comment Share on other sites More sharing options...

michaelmorris Posted February 2, 2009 Author Share Posted February 2, 2009 I've been looking at this picture for a couple of days thinking something wasn't quite right; and then it struck me. There is a strong light/dark dichotomy running straight through the middle of the ghost crater Daguerre in the top right hand side of the Mare Nectaris!Damn it, gosh and crickey I thought. How did I miss that? It's obviously it is either an alignment point artefact or a rather crude photomerge in Photoshop. Anyway, the first thing I did is check the original AVI file and [removed word] me backwards with an LX200 if the it isn't a natural feature! It's there in the original AVI, clear as day.

legion48 Posted February 3, 2009 Share Posted February 3, 2009 Anyway, the first thing I did is check the original AVI file and *beep* me backwards with an LX200 if the it isn't a natural feature! It's there in the original AVI, clear as day. Yes, I've seen that on other images of the area. I do see a possible mosaic alignment error though. It runs from the top of Rosse all the way to the right edge of the image. Link to comment Share on other sites More sharing options...
michaelmorris Posted February 3, 2009 Author Share Posted February 3, 2009 Yep. I see it. (dashit, thunder and damn) I know exactly how this came about as well. I forgot to crop out the white 'stack' line before creating the mosaic. Here it is re-processed, now without the crop line. Link to comment Share on other sites More sharing options...
