These are my narrowband versions of the IC1396 aka Elephant's Trunk Nebula (technically IC1396A). I couldn't see this image in Stellarium so I didn't realise how large it was with my FC100DF setup but I was itching to image something with this scope and so I decided to go for it. I was able to capture the Elephant's Trunk region in the greater IC1396 nebula but if I had used my SV70T I'd have gotten the whole thing. I'm still looking for some good targets to image with this scope since I find it to be just the right size to take out the whole setup (with EFW and camera attached) and move it in and then put it back. It's the ideal sized scope (the FS128 is too big especially since I won't be around the entire summer and the SV70T has a nice widefield but it's 30mm less aperture).
