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.
Best,
Christian
Hello everyone,
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.

Object Name: NGC 2392, the Eskimo Nebula
Object Type: Planetary nebula
Location: Asturias, Spain
Date: February 20th, 2012 23:30 UT

NELM: 5.5, moderate light pollution
Clear and dark skies!

Aloha!
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.

Hi
This is a sketch of M1 the crab nebula with my 10 inch F4.5 reflector viewed with a Watec 120N+ astro camera, the resulting live view was sketched from the monitor.
The Watec literally doubles the size of your scope so my 10 inch behaves like a 20 inch or slightly larger depending on the conditions.
The view was incredibly detailed and took about an hour to draw.
Cheers
Object Name: NGC40 (also Caldwell 2)
Object Type: Planetary Nebula in Constellation Cepheus
Observing Location: Sudelfeld, Bavaria, Germany
Date: 16. November 2012, 11:50 PM
Observer: Christian Rausch
Telescope: 12inch/F5 Dobson (Hofheim Instruments)
Used Filters: none
Power: 300x (Nagler 5mm)
Conditions: SQML = 21,45 mag/arcsec*2, seeing good, transparency very good, Temp. +3C, rel. humidity 40%
Media: Chalk pencil on black paper
The night from the 16. to the 17. of November was exceptional here in southern Bavaria. A very good transparency combined with good seeing conditions is very rare in our area. In addition the fog down in the valley damped the artificial lights.
It was a great night!
Best Regards

M8 (the Lagoon Nebula). A very large and bright nebula sketched in Warren county NJ on 09/16/2012. Sketched on a laptop computer at the eyepiece.
Orion Astroview 100 Refractor F/6 32mm Plossl 19x.
A brief window to observe the deeper sky was taken tonight as it was clear, dark early and with the moon not due to interfere until around 20.30ut.
As has become the norm, I was intent to grab another of the 100 Hickson groups, but before I did this and as Altair (Alpha Aquilae) was a stop off on my hopping progress up into Pegasus I took a look into Mark Bratton’s excellent Guide to the Herschel Objects to see what was local. I picked up on NGC 6781 which is a beautiful mag 11.8 planetary in Aquila with plenty of exquisite detail to enjoy. Compared to M57 the Ring Nebula in Lyra it is relatively large and faint, yet not so faint that it isn’t visible in smaller, say 8” telescopes, I feel it is more akin to the Helix nebula, though considerably smaller at 2.0′ diameter.
At 16.8 magnitude, the central star (a white dwarf) is clearly seen just off centre in my sketch, made using the 500mm mirror, Watec 120N+ video camera of course! Sketched in pencil on white and then inverted on the computer.
No time to spare, one sketch in the bag, yeeha!, with the Moon getting ever closer to the horizon, I pushed onto Hickson 99 there are 5 members in this group which is located just SW of Alpha Andromedae (Alpheratz) in the square of Pegasus.
(A) member UGC12897 mag 14.8 is extended N-S with a star on its southern tip. (B) UGC12899 is round fairly bright at mag 14.7 with a brighter nucleus. I find (C) PGC 58 to be the most interesting, it is a barred spiral and despite being only mag 15.6 I was able to see and capture arm structure in my sketch, amazing J (D) & (E) members PGC 60 & PGC 57 respectively at mag 17.1 & 17.6 are merely tiny smudges to the south of the 3 main members.
I was very pleased with this short and productive observing session, time to close up and return to the family & gardeners world indoors!
