NGC7027 – Planetary Nebula in Cygnus

NGC 7027
NGC 7027

NGC7027 – PK84-3.1

Object Type: Planetary Nebula

Location: Barcelona – Spain

Located in a poor stellar field, I could see NGC7027 at 235x little, homogeneous bright and with an elongated shape, almost as a rectangle. But I could not perceive any halo around the bright planetary core. With the OIII filter I could see the nebula with more contrast, but no details.

With 313x, better adapted to the dark and using averted vision, I saw with satisfaction an evanescence halo around the core, which seems to split in half, like an ?8?.

Easy planetary to detect, but difficult to see details on it.

NGC 6826

NGC 6826

Object Name: NGC6826, the Blinking Planetary
Object Type: Planetary Nebula
Location: Terneuzen, the Netherlands
Date: 21-06-2012Media: Photoshop, using several layers to make it smooth
NELM: 5.8
Seeing: average 6-7/10

This sketch was made using a 8 inch newtonian telescope on an HEQ-5 Pro from Skywatcher. The magnification I did used was around 400 times.
The central star was seen with ease and the ‘blinking’, where this planetary is known of, wasn’t seen with the magnification I used for the sketch. After several minutes of waiting for moments of good seeing, I noticed something strange. Something I haven’t seen in other sketches with the same aperture. It was a central bar, running from one end of the oval planetary to the other. Really nice to see a surprise like this.

After checking the internet, I’ve found some sketches and observations of some brighter parts of this planetary. At both end of the over planetary, there are some spots which are called FLIERS. Together with the brighter central spot and some ‘average’ seeing, it would probably merged together and be the reason for seeing a ‘bar’ instead of three brighter spots.

28 is 28 & Cleopatra had her beautiful eye on me!

HCG 28

A bitterly cold night that saw the mercury drop to the lowest level I have ever known or recorded -16?C. I wanted to get an early observation in before Moon rise; my primary objective was to add another Hickson group to my list. This I did successfully with very appropriately HCG 28, I say appropriate as this was the 28th that I have observed and sketched. Located in Eridanus there are 4 faint members in the group although my sketch actually includes a 5th galaxy which isn’t a member and is depicted as a faint star. All members have PGC listing the faintest & smallest (d) member is Mag 18, so serious stuff! The commanding member is a nice edge on PGC 15136 running N-S, see my sketch here
Quite how I came to observe the next object I’m not quite sure? I may have noticed it close by on my planetarium software, not that it matters, it was an interesting and valuable observation. Again in Eridanus, NGC 1535 is a lovely planetary nebula, named ‘Cleopatra’s eye’ by Greg Crinklaw aka ‘The Skyhound’ a name that appears to have stuck and grown in popularity. I had observed this planetary back in 2010 with the old 350mm F5 and older first generation Watec camera, but this was my first visit with the 505mm mirror. It did show an improvement, despite the lower focal length employed on this occasion, I used a barlow lens previously to increase image scale and try and pull out more detail, I had failed to resolve a faint star on the very northern edge of the nebula, the central star was easy and steady as were internal annular ring structures rather like those in the ‘Eskimo’ nebula.
Here is my old sketch with the 350mm and here is the latest with the 505mm. At the time of writing I have asked Sue French if she would be so kind as to help assist me on finding the outer stars mag.
Happy days, Dale

The Blue Snowball

NGC 7662
NGC 7662

In a cold night last December I decided to spend some time observing NGC 7662, the Blue Snowball nebula in Andromeda, and the observation resulted in this sketch. At low powers it looks like a fuzzy star that shows a remarkable bluish color, which is probably the most evident color I’ve seen in a deep sky object. At high powers that color is lost, but the nebula starts to show a low contrast annular structure: it appeared to me as a slightly oval, thick ring with a small, not very dark central zone. The whole nebula had a “mottled” appearance, but no additional detail was visible.

Dumbbell Nebula

Object Type: planetary nebula
Location: Płaza, Poland

Media: graphite pencil, white paper, inverted

Dumbbell Nebula (M27) is a beautiful planetary nebula located in our galaxy. You can observing it at warm, but very short summer nights. When you’ll look at eyepiece, you’ll see the big nebula and a hundreds of stars, because this nebula is cut by one of our galaxy’s arm.
