 With careful composition, you can include a wide variety of nebulosities in this highly interesting field that is located near the foot of Gemini. This deep exposure on a very transparent night is dominated by NGC2174 in Orion at the bottom right. This huge object is an emission nebula that is 30 arcminutes in size and visible in a pair of binoculars on a dark night. Although no official cluster lies in the center, a 7.6 magnitude O6 star HD42088 lies at its center providing ionization.

Just above it is the small patch of nebulosity known as Sharpless 2-247, an 8 arcminute emission object. Just above mu Geminorium - the bright orange M3 star at upper left is IC444, a huge extended faint object nearly a degree across. The star attraction in this are however is IC443, the arc of nebulosity to the right of mu. This is a supernova remnant in which you can see the entire shell here off to the right.

Processing: Two frames scanned with Nikon Coolpix LS2000, aligned and stacked in PixInsight. The erosion filter at half a pixel radius in Pix was used to cut the number of stars to half intensity because they were so overpowering. Final adjustment, and cropping in PS.
