Tulip and Crescent Nebula Widefield

[RobertM]

I'm not quite sure what happened here as the camera drifted quite a bit during the session.

These two look like they're in a dance around the dark part near the center, kind of strange the way it's worked out!

From the imaging run last night I managed to get 19 x 600s of almost usable subs so here it is:

Very nice Robert!  Conditions were really good that night for around here and you've clearly taken advantage of them.  Your image goes pretty deep.   I love all the "waves" in the background.

On the annotated version, why doesn't the Tulip have a reference?  And does Do4 have a more familar name?

Thanks Mark.  I used MaximDL for the overlay but it gives less detail when zoomed out; I'll see if I can stitch together a closer version which shows the Tulip designation, from memory I believe it's a Sharpless object.  I'll also check out Do4, I'm sure some American has given it a name somewhere
