Nice dark clear skies tonight so had a go at these with Tasco 4.5" f8 reflector & 21mm EP (43x). First up, there's a lot of mottling in the vicinity with a fairly dense starfield.
Gum 50 was fairly easy to see, a faint, smooth, oval nebulous patch about 3' long and about half that wide, best viewed in averted vision (strong & could be held).
Gum 49 was a different story - the strongest 'signal' was a faint elongated patch as marked in the attached sketch, but in-&-out and not a terribly satisfactory observation at all. At times I 'imagined' I could see more but I think I was kidding myself. With the sketches, there were of course many more stars in the fields - those drawn were just my markers.
Should be a doddle for a bigger scope.
