Hi all. I managed to get a little imaging time last night and decided to try a little narrowband... given that big bright moon. So I trained the scope on M97 and collected data all night. I had lots of bad frames for some reason, but got 6 each Ha and OIII frames to combine. I used the OIII for green and blue and the Ha for red. Attached is a crop of the Owl himself.

Notice that you can begin to make out the larger shell that is very faint. I may try to get some additional data to pull that bigger shell out a little better. It does not show up in most images of the Owl.

Here is a link to my website. Click the thumbnails for the "clickable" full version.

Comments and suggestions are always appreciated.
Cheers,
Tyler

Tyler,
Thats a very nice owl. I think the narrowbands show a lot more feature in this object than straight RGBs.

Great result Tyler.
I have never noticed an outer shell in any Owl images before,I do see it in yours,cool!
When your 3200 chip comes back to you I expect it will get deeper,faster.

Nice work!
