A fierce dragon in Vela. The dragon's head is about 40% of the way toward 8 o'clock from centre. Leathery wings fill the frame. Part of the Vela supernova remnant around open cluster Pismis 4.
Despite being only a tiny (and faint) part of the entire Vela SNR, the degree of roiling, boiling loculation is amazing.
Green: H-alpha 5hrs; Red: SII 9hrs. Blue: OIII 10hrs., in 1 hr unbinned subs. Field 36' arc. Aspen CG16M on 20" PlaneWave.
