NGC 6741 - Detail
The object looks very stellar-like in the image below - it appears similar to
the adjacent 'bright star', but may be slightly elongated, at least more
than the other stars in the image which are subject to some poor RA tracking/guiding)

Image details as above
 
NGC 6741 - Alternate Image
The object looks to be less stellar-like in the
square root scaled image below - it is larger in size and
has lower 'surface brightness' than the adjacent 'bright' star

NGC 6741 - through 'Star Analyser 100'diffraction grating
The object's true identity of NGC 6741 object is shown in image below where its
classic Pl.Neb spectrum allows it to be easily distinguished from the stellar spectrum
of the adjacent 'bright' star (GSC 5128:756, mag +12.7)
