M3-1 and M1-13, 2 small Planetary Nebs

Havent had good weather for a while so deciced when I finally got a clear night with no work the next day to go for some small but fairly high surface brightness Planetaries

Here are full res. crops of the objects

First is M3-1 in Canis Major. 7x5 mins ISO200. Longer subs saturated the nebula. 2 faint "wings" just visible. Star Atlas Pro reports it as being mag 13.28 in H beta and 11.2 arc secs in size

2nd is M1-13. 4x10 mins ISO400. Both with uvir and uhc-s filters, modded 350D, 10 inch f5.6 newtonian. Mag 14.6 3 and 10 arc secs.
Warm night at 25 degrees, 80% humidity.
