Organic Astrochemist asked me, "I'm curious, in arriving at this list, about how many objects did you try to observe and found that you were unable to do so?"

Well, I didn't keep track of my failures because I ended up with way more successes than I could've dreamed of. I'd have to say that there might have been 20 that I found but could only make out with the 3-inch mask or none at all. The reason I didn't have too many failures was because I went down "the list" from brightest to faintest and as I got into the 12.0 - 13.0 range I had to make sure to only try for stellar or nearly stellar ones. I plan to do a 75mm list sometime and hope to see as many of the NGC/IC PNe as I can in the coming years.

My magnitude estimate on NGC6620 in Sgr was a little bit too hasty last week. I revisited NGC6620 last night and visual magnitude 12.5 is more accurate.

 

There are plenty of bright anonymous planetaries in the deep southern skies which I have viewed the past nights.

In a quick look, NGC6620 was about as bright as the V=11.49 star 2.1 arc-minutes WSW.  There was a brighter star just 1.0 arc-minutes SE of NGC6620.  With 10-inch and 170x power NGC6620 appeared as bright, very small and looked liked a diffuse star (tiny disk).  The planetary was at 52 degrees altitude.

Thanks for the update Timo - I went back to my info and found that NGC 6620 was listed at +12.7 And I had tried for it but could only make it out with 75mm instead of 50mm. Will give it a second shot though in September!

No worries Scott! I tried to see the distant star between M7 and M6.  No luck, the galactic background is too bright for this guy naked eye. It is still easy with binoculars.

No, but I want to observe them more in the coming future.  I have the perfect scope for it too, so I will attack them once I get some clear skies.

 

Thanks for the list.

Thanks for the list, it has moved me to start to go through and see how many PNe I can find! I started last night and in about 90 minutes found NGC 7008, 6210, 6826, 7662, and 6543. Also visited M27 and 57 again just to complete the night.  These little guys are fun to find and zoom in on. Most of my observations were done at 320x after locating them at around 75-100x. I misplaced my barlow, or else I would have tried pushing past 500x...confused1.gif

 

Edit: I live in a bortle 5/6 area.
