The Tulip Nebula, or Sharpless 101 (Sh2-101) is an emission nebula located in the constellation Cygnus.
It is so named because it appears to resemble the outline of a tulip when imaged photographically.
It lies at a distance of about 6,000 light-years from Earth.

Imaged over several nights in June-October 2016
S2-Ha-O3 mapped as RGB
RGB for the star colors

Ha - 49X600sec
O3,S2 - 10X600 sec each
RGB - 30 min each

Total about 12.5 HRS

All images at Bih 2 = 0.89" per pixel (so 12.5 hrs at bin 2 equals 50 hrs in bin 1...)

C14 equipped with Starizona SCT corrector (operating at F7.2)
ASA DDM60 - no guiding :)
