Constellation: Pup
Data: mag 12,6  size 36" ?
Position: RA 07h:55m 11s  DEC -23°:38' 13"
Description:
Pos: 07 55 11 / -23 38 13. Appears as a very faint slightly oval disk of 
approx. 15" size. The edge of the nebula is fading away and the object is 
brighter towards the center. Easier (though still difficult) to see with the 
OIII filter at 342x magnification. M3-4 is located 2,5° E of the cluster M93. 
The brightness given in Uranometria (11,8) does not seem to be true, nor is the 
size (34") corresponding to my own observations (~15").
