LBN400 (SH-119)

Here is an image of LBN 400 (or SH-119). It is an emission complex east of the North American Nebula. I have attached a mid size image. A full size image and exposure / processing details are at:

http://jthommes.com/Astro/LBN400.htm

Scope was Megrez II at f/4.2 and the camera was an Artemis285.

Exposure time was 67 minutes

I had some funny halos on the stars due to the heavy stretch. And I think I had some gravitational sag in the set up - the stars on the right are softer and less focused than the stars on the left.

Nice job.

Thanks for the comments guys..

Tom and Stefan,
Yes, I have not seen many images of this object. More out there but as you say Tom, so little time.

Hi Jim!

Very nice! Thanks for sharing the obscure objects. It helps to add to the list of targets 8)

When I saw the term "gravitational sag" I briefly thought you found a new phenomenon out there. I guess it turned out to be a little more mundane. grin

Great shot Jim!

Eric, Tyler,
Thanks for the comments..

Yeah, I guess "gravitational sag" is too hi-falootin a term to use to describe a sloppy camera mount. wink
