The Tulip Nebula is the big red things in lower-right of the image. It's part of the Sharpless catalog, number sh2-101, which lists red stuff like that. We call it HII regions, clouds of ionized hydrogen in h-alpha. It is only accessible in photo, our eyes are not sensitive enough to see them in a telescope.
And in the center on the left, the small packet of bright stars, it is the open cluster NGC 6871.

29 exposures of 5 minutes.

Lovely shot.  Your image capture details mention 1000D unfiltered.  Picking up heaps of Ha with unmodified camera.  Nice one.

Thank you :)
But my camera is modified. I removed greenish ir-cut filter. It is what I call "unfiltered" ;)
