Description:
This Planetary was very difficult to see, it's listed V mag of 13.7 and the DSS
image made it seem a straightforward enough target but it proved to be very
elusive, it did not show at all at any magnification without the OIII filter
but once that was used it gradually came into view, I had a black cloth to
exclude any stray light and slowly a faint smudge of light showed itself in
the correct position, oddly enough once I had found it it became a little
easier to see this was partly due to the improved dark adaption of the cloth
but also because my eyes now knew what they were looking for, and whereas at
first it was only visible with averted vision I could now look straight at it
it took nearly 30 minutes to find!!
