Jones 1 Pegasus Planetary Nebula.

SPX350 F4.53, EQ6, ATK-16HR, TS-9mmOAG.

This is extremely faint pn radiating mostly O3 with tiny Ha patch below annulus.

This is one of the faintest pn around so I tried my new Astrodon 3nm O3 filter and it worked brilliantly in bringing out contrast. This pn is 332" wide and 12th mag with 15th mag central star seen as the blue star in the central group of stars. There are not many images on the web of this object so am pleased with result, pretty noise free with Astrodon filters.

OIII 3nm=8x15mins unbinned.

Ha 5nm=9x10mins 2x2binned.

RGB=5x3mins unbinned.

Thanks, JohnH.

very very nice there

good job

[moocher]

Nice John!!!! Like you say you don`t see this too often. Good looking object but you need some serious aperture to get the best out of it.

Very nice image, I think that is way beyond my capabilites but it looks great in your photo.

Lovely image - not seen this one before but I will certainly be looking out for it in the future.

[Whippy]

Superb result John, reminds me of the headphone nebula .

That's a quality image John, love the colours of the two central stars, one vivid blue the other a glowing red... very nice, btw, looks a bit like your avatar except colours!?

that's a nice image. It would take considerably longer to reach the same SNR at a more aggressive image scale.

one comment; the noise doesn't arise due to the filters, it is a function of the camera, and in particular the quality of the sensor adn the cooling. SNR is widely misunderstood in the amateur astro imaging community and I am preparing a treatise to explain it properly.

stay tuned

Very nice capture John, lovely image scale and nice tracking with the OAG and that sub lengh/focal length.

One for my 16" dob and O111 filter I think.

Btw fantastic picture.

[narrowbandpaul]

a treatise of SNR......i can hardly wait.

dont skimp on the math! its the best bit.

have you heard of EMVA 1288?

Nice to see a different and challenging target John, thanks for sharing it with us.
