Orion’s Belt Mosaic. Upper frame is 50×60 sec @ ISO 3200, plus 40×60 @ ISO 6400. The lower frame is data from 2007, 31×180 sec ISO 1600 and some 2013 data that includes 40×180 sec ISO 1600 sub-images. Finally, there are 3×180 sec @ ISO 800 sub-images that were taken on Nov 2, 2014. Scope and camera used were a TV-85 at F/5.6, IDAS-LPS filter and a Modified Canon T3.
Here’s one that’s in progress. I shot this area over two nights. I have very little of the Horse Head region from these sessions, but another 40 subs of the belt stars upper frame area. I should be able to put something together with other data from older sessions and get a somewhat complete mosaic image. (Update: Yes, I was able to add some old data and smooth it out.)
