Hi Folks,

I've drafted up a challenging list of planetaries for this summer with Sasa's help. Some we have seen, others have not yet been seen. Some are easy and done are very very challenging. I've tried to keep the magnitudes maxing around 12.5v so with a UHC, OIII or Hbeta they can still be had from less than optimal sky's.

If anyone wants to add to the list it'd be great.

List: Small Bright planetarys Summer
NGC 6891 Planetary Nebula in Delphinus
NGC 7027 Planetary Nebula in Cygnus
Blue Flash Nebula - NGC 6905 Planetary Nebula in Delphinus
Blinking Planetary Nebula - NGC 6826 Planetary Nebula in Cygnus
NGC 6210 Planetary Nebula in Hercules
IC 4593 Planetary Nebula in Hercules
Little Gem Nebula - NGC 6818 Planetary Nebula in Sagittarius
Saturn Nebula - NGC 7009 Planetary Nebula in Aquarius
NGC 6572 Planetary Nebula in Ophiuchus
NGC 6886 Planetary Nebula in Sagitta
Vyssotsky 1-2 Planetary Nebula in Hercules
Henize 2-327 planetary in Sagitarius
ARO 11 Campbells Hydrogen Star, Planetary Nebula in Cygnus
UGC 11668 Egg Nebula listed as Galaxy in Cygnus in Sky Safari
Footprint Nebula - M 1-92 Bright Nebula in Cygnus
Humason 1-2 Planetary Nebula in Cygnus
NGC 6778 Planetary Nebula in Aquila
NGC 6884 Planetary Nebula in Cygnus
NGC 7026 Planetary Nebula in Cygnus
IC 3568 Planetary Nebula in Camelopardalis
Box Nebula - NGC 6309 Planetary Nebula in Ophiuchus
NGC 6369 Planetary Nebula in Ophiuchus
Phantom Streak - NGC 6741 Planetary Nebula in Aquila
NGC 6803 Planetary Nebula in Aquila
IC 5117 Planetary Nebula in Cygnus
IC 5217 Planetary Nebula in Lacerta
PK38+12.1 planetary in Ophiuchus 12.5v to 13.5v depending on source

Thanks Pete for the list. There are definitely names I did not hear about before and it is a good inspiration. I'm sure, people can add few more candidates.

Excellent list, Pete. Listed planetary magnitudes can be all over the map, but Henize 2-327 is probably closer to mag 14.5, based on a visual estimate I made back in 1987 in an 18" (described as "very faint" in that scope).

This planetary was first discovered by Minkowski in 1947, so the discovery name is M 2-24. The position is 18 02 02.9 -34 27 47, if others want to take a look and compare. I'd suggest blinking with an OIII or narrowband filter as the size is quite small.

Thanks, guys. Steve thanks for the clarifier. My stellar faint mag limit is 15 but the sky's I use now are nearly a full mag brighter so my Minkowski choice may have been rather optimistic. I doubt ill see all but I feel good about a lot. Thanks for your comments!

You may want to add NGC 6781 and NGC 6804 in Aquila and IC 1295 in Scutum to your list.

Done! Thank you David. I've seen those two NGCs and they are nice but not the IC just yet. I'm looking forward to it.

NGC 7139 in Cepheus is somewhat tricky (NGC 40 in Cepheus is much easier). NGC 6337 (Scorpius), which was an Object of the Week over at Deep Sky Forum, is another cool one. And don't forget the Bug (NGC 6302) while you're there!

IC 1295 is interesting; I've seen it from the Cincinnati suburbs in an 8" SCT with a UHC filter, yet some reports consider it difficult with similar gear in rural skies.

I am working on this list right now. Question-in Scutum I think it is IC 1298 right next (or in) globular NCG6712. I had a broad band on and cranked it to 190x. I could not pick that thing out. I stared and swatted at mosquitoes and searched and stared and swatted at mosquitoes to no avail. Is this one that requires even higher mag or must have an OIII? Any tips?

Pete,
In a reply to a recent post of mine, you mentioned the bright planetary NGC6543 in Draco, the "Cat's Eye Nebula". It is an easy one, as I was able to pick it up yesterday. It is well placed for summer viewing.
Regards,
JCF

Son of a gun, I omitted 6543!!! And I had it in my head to put it on the list!

Editing.

Aatt: I looked on Safari and the magnitude is omitted - not a good sign!!! I'm thinking it may be incredibly small and very very faint. More over Safari lists it as a multiple star, not a planetary. Hers a link with a graphic - I think its non nebulous. However Burnhams sais: 14th magnitude 17 mag central star, 80x60". Hmmm.

Kid Orion: NGC40 and NGC7139 are great. The other is farther south than I look for seeing reasons but its a nice call.

IC 1295 is the planetary nebula in the vicinity of NGC 6712. Using a narrowband or OIII filter will make it much easier to see.

Hi Pete

It's a great list of small planetaries, for sure, but I wouldn't call most of them challenging. At least, *I* wouldn't... ;) Most are very bright, mag 8 - 9.

I would call the list "the best small summer planetaries". I've seen many of them in my 63mm, as you may know.


Clear skies!

Thomas - in my light pollution its challenging lol. I agree these are not truly challenging - Ive seen far fainter - but for the magnitude and size of the smallest its fairly challenging for me anyway. The bigger brighter 6210 and other beacons I added on a little later so it became more generalized. I've changed the title per your suggestion.

Great list as I really like these more and more. Should I use my narrowband filter for most of these in my 8" SCT?

Thanks for posting!

Bob I would . I find most all planetaries respond well to a UHC or an OIII . Some peculiar ones like ARO11 (Campbell's Hydrogen Star) show better with an HBeta.

I did not have anything better to do, so I put your list into a spreadsheet, and added comments from three references, Sue French's wonderful "Deep Sky Wonders", Massimo Zecchin's "Brightest Planetary Nebula Observing Atlas" (downloadable), and Martin Griffith's "Planetary Nebulae and how to observe them". I have it in spreadsheet format. Take a look. I hope I did not transpose any entries. The different references do not agree 100%, even on magnitude or size, not to mention appearance. I can only attach one file at a time, apparently. If you like, I can send it out as a pdf, as well.
Note to self... spend less time at PC, more time observing...

Regards,
J.C.F.

Alright, Pete, when the skies clear I am up for the challenge of completing your (updated) list. Post some observations and some sketches, I will when I can.

Thanks for the spreadsheet . Some of the comments are interesting. Where applicable I always refer to Skiff and Luginbuhl . Nice to see some other remarks too.

I definitely want to take a look, guides like this help. . What's the best way to plan them out? some of them aren't coming up at reasonable hours. . .Like the egg for example I defiantly have that on my must see list. is there something you guys use that helps you plan the best times to view them?

I'm using the length of summer and some fall. When I go about it - and Ive seen half or so of these already, ill mix it up a bit with easier and more difficult. I haven't done it in a while as my mirrors older coating dissuaded me from trying anything challenging (beyond mag 10 under my sky's), but that was my M. O..

The really small stuff does best on steadier nights even if its not the clearest of all.

All of the constellations listed seem to be best viewed in the summer time, except for IC 3568 Planetary Nebula in Camelopardalis and it is close to Polaris, so still viewable. Remember that NGC numbers increase with Right Ascension so if your view of the sky is limited, start observing with the lowest numbered object in the area of sky that you can see and view them as they rotate into view. First find all of them on your atlas before trying to view them, it makes finding a logical order easier. I think when you do this you will see that almost all of them can be viewed in the evening.

P.S., This is up at a very reasonable time now. CRL2688 = PK 80-6.1 = IV ZW 67 = UGC 11668 = the "Egg Nebula". It is located within Cygnus at R.A.= 21h 02.3m; Dec.= +36d 42m
