Congratulations on such a good night, and glad you put it to good use!
NGC 1999 is one I have nabbed a couple of times. In Jan last year i noted
NGC 1999 Emission Nebula in Orion
RA 05 36 30 Dec -06 42 00 Dim’ 2x2 Type E BC 1-5 Colour 1-4
From Iota Orionis a narrow 45’ long isosceles triangle points Sf. S star is mag 6, faint pair of mag 8 stars to Sp, target is about 15’ to p of these. Moderately bright small nebula, at 115x appears just larger than stellar with an outer envelope. Could be mistaken for a small globular. UHC Nebula filter has some effect at 115x. There is a dark structure which is clearly shown in DSS image (see http://spider.seds.org/ngc/ngcdss.cgi?obj=NGC!1999&r=5:36.5&d=-06:42&e=J2000&h=19.2&w=19.2&f=GIF&c =none ) but couldn’t be made out.
and had another go on Dec 23. I noted that there appeared to be a faint star superimposed which became evident at 150x
