I find it with the eyepiece from 20mm to 80x and it appears as a very bright, very large and oval object.
The observation is done with an OIII filter and the TV D eyepiece of 14mm at 119x that offers me a much sharper and more contrasted view, although with the background a bit brighter, than with the TV N2 eyepiece of 12mm and 132x. At 200x with the 8mm TV D the image loses a lot of sharpness, probably due to the low height on the horizon in which this object culminates it makes it more critical to the increases. From the beginning, several unusual details attract attention in a planetary nebula: the high surface brightness, its unusual shape and the high brightness of its central star. Its silhouette is almost identical to that of an egg with an obvious darker area around it and especially above the central star. The surface presents delicate changes of brightness where the SE side is weaker (better to look at the drawing above, made on the sketch made in this observation). The brightness variations were detected with side view, zone by zone since in general it seemed more uniform. Highlight the sensation of rhombus rather than egg that was constantly transmitted to me when I had been observing it for quite some time, perhaps due to those variations of brightness that I was not able to appreciate but to perceive, which I had when observing in a general way.
