C19 Cocoon Nebula... What am I doing wrong? Very frustrating DSO

Recommended Posts

Hi guys, 

Basically, I have been hunting for it AGAIN tonight with my XT8 and various EPs. No luck. I can spot the Blue Snowball Nebula very easily and that is fainter.  I am using Stellarium to navigate with my RA finder and this technique usually works very well. And yet...

So my question is, from everyone's experience, is this puppy a harder target than others to spot? Would a UHC filter help?

Thanks for reading. 

Cheers

The Cocoon Neb is a tough one to observe. It needs really dark skies and it's actual surface magnitude is a lot fainter than the integrated magnitude figure that is quoted for it.

It is one of a relatively small group of nebulae that a H-Beta filter makes a positive impact on. A UHC will have a small improvement. Even with the help of these filters it is regarded as a challenge. Not quite as hard as seeing the Horsehead Nebula but getting towards that sort of challenge.

The Blue Snowball has a much brighter surface magnitude and much higher contrast.

I'm sure it is not your technique but the challenge of the target that it the cause of your frustration.

You will have to travel to very dark skies and probably use a filter

Thank you.
