My friend Robert always writes a column in our Astronomical magazine, where I proposes objects to observe. This winter the Planetary I 2149 was on his list.

 

I just observed it with my 4 inch refractor. It is not a real great sketch. I show it here that you can see what can be detected with a moderate aperture.

 

The sky is full of wonders.

I observed this small, bright planetary nebula back in January 2011 with a 94/1300mm achromat at 742x:

The two FLIERs (Fast Low Ionization Emission Region) could be seen, one quite bright and easy to spot, the other much fainter and harder to see. 

 

Compare with this high-resolution 2017 image from a C14: http://yamachan.la.c...C2149photo.html

 

 

Clear skies!

Wow! Nice catch Uwe! Was this from a dark site? Magnitude 10.2 object with a 100 mm refractor is absolutely bookin' it! Telescope.gif drool.gif bow.gif waytogo.gif

This was form city, fst around 4m5. The nebula is bright enough to resist moderate light pollution.

 

10m2 is not a problem for a 54 inch instrument. Limiting magnitude form city is around 12 mag or slightly dimmer.

Ha, yea...I am a bit more conservative. But, as Uwe said, it is bright enough and it can stand very small exit pupils as Thomas can attest. I probably could have pushed it a little more. (Forgive the incorrect label).
