Hi all
With another cold, clear night, I thought Id go for some Integrated Flux Nebula (nebula lit only by background starlight) near IC 4633. It is VERY faint, only the core of IC 4633 was just visible on the subs, the nebula not appearing till after stacking. Lot of gradient to remove, and had to do it without dimming the nebula. Strongman Mike has a great image of this.
19x10 mins ISO200. Unfiltered. 6 inch f3.6 SN with MPCC coma corrector. Hutech modded 350D camera. Ambient temp 8 degrees.

In the days of film Id never dream of capturing this from my light polluted skies.
