Located in a rich star field in Scorpius, i tried to see the central asterism of the nebula but i couldn’t (only the brightest star). Link of the asterism here: http://www.capella-observatory.com/images/PNs/NGC6337.jpg. I’ll try again in rural skies.

NGC7354 is a small, slightly faint planetary nebula in Cepheus. Through the telescope, it is located the middle of a star pattern that resembles Sagitta where Delta Sagittae would have been. The star pattern consists of TYC4265-877-1 (m11.7) and USNO J2240137+612011 (m13.2) to the north with TYC4265-347-1 (m10.68) to the south. A strand of three other stars to the west, along with the pattern of stars that resembled Sagitta and NGC7354, resembled the shape of an ear or an ammonite fossil.
75x magnification: Small, soft circular disk, with a hint of slight elongation. O-III adds contrast and there was a hint of brightness in the center of it. A 14.75 magnitude star to the southwest and a 15.3 magnitude star to the southeast of NGC7354 were observed at this magnification just outside of the disk.
225x magnification: A third star with a magnitude of 14.9 was observed just outside of the disk to the west. Using an O-III, the NE and SW edges of the disk were fainter and I could see a brightened edge to the nebula around the rest of the disk with a fainter center. I detected a faint, diffuse haze outside of the brighter borders and there may have been a hint of the central star as it looked slightly grainy in the center of the disk.

Hi, I send my sketch of Messier 27. This is nebula planetary.on Sunday, September 16 I had an exceptionally good observing conditions. For 8 “telescope, you could see clearly the object like a dumbbell to exercise. Addition, animal noises from the nearby meadows are doing an amazing experience during the observation.
Observation notes:
New 10” dob telescope. UHC Filter. Male 6.1 Object Elevation +27 º
Location: Medium difficulty. It takes about 5 minutes with 40x distinguish. It appears as a faint gray smudge.
Brightness: Brightness weak with the contour more dense and its inner surface with less dense areas.
Size: Small, but notable for being a planetary nebula.
Shape: Round, somewhat flattened.
Field: About 50 stars accompany this nebula campo.Visualmente 1 contains several starlets that give a cheerful.
Best picture: With 80x distinguish brightness irregularities on its surface and a small “bite” in the outline.

Additional information:
I am working on a personla project that involves the observation of planetary nebulae that have cosmic companions in close proximity (less than half a degree in angular distance). The sketch shows the most spectacular of that list of 14 PNs. b
I first observed NGC 2438 and PK 231+4.1 individually in 2010 from Tucson, AZ, USA. It was not until lately that I realized that both PNs as well as the biggest part of M 46 would fit in a single FOV when using low power.
On November 16th, I was able to observe that beautiful part of the sky with my 18″ Dobsonian telescope having superb conditions (fst 7m0). The sketch was made at 94x and I noted: M 46 and NGC 2438 are brilliant as usual. NGC 2438 shows a distinct ring structure and is very bright. Filters improve contrast. PK 231+4.1 is quite weak and definitely requires a filter to be seen. I first needed 226x in order to see that faint planetary nebula. Once spotted and located, it can also be seen at 94x together with the other two objects. PK 231+4.1 also shows some extent but is way smaller than NGC 2438.
Here is an sketch of the great planetary NGC 2392, the Eskimo Nebula in Gemini, from a cold but quite good night last winter. The following are my notes from tat night.
Easy to find starhopping from Delta Geminorum, the Eskimo Nebula is visible as a pale blue, fuzzy disk at low powers, in a rich star field. I get the best view at 222x. The 10.5 magnitude central star is easy to see and the basic structure of the nebula is also visible, with two concentric zones of different brightness. There is an inner, bright disk that envelops the central star, and a second, concentric halo of approximately double diameter. This second halo is fainter and smooth. But after some time observing, there’s something more: in some moments, I think I can see a bright arc in the Eastern limb of the inner disk. It appears and disappears, but always in the same place so I assume it’s a real detail.

I submit a favorite observation, NGC 7293 the Helix Nebula located in the constellation Aquarius. My first impression even without a filter was “Wow, that is really big!”. And it is, measuring 16’ in diameter or about half the size of the full Moon. It is also the nearest planetary nebula to our solar system at a distance of ~650 light years.
Though I could see the object without aid of filters, OIII & NPB filters brought out far more detail. Some fainter stars could be seen with averted vision within the nebula as well as a multi-layered mottled shell like appearance. I have gone back to this object many times trying to “see” more with longer observations.
