Jones-Emberson 1 aka PK164+31.1 aka the Headphone Nebula

[RickS (Rick)]

Another image combining data from multiple scopes, both at DSW in New Mexico. The TEC 160FL belongs to Jim & Linda Powell. The RCOS 14.5" is a shared team scope.

Jones-Emberson 1 is a largish, low surface brightness planetary nebula in Lynx. The central star is a very bluish white dwarf.

Scope: TEC 160FL FL=1152.68mm (OTA #30/TEC-FF)
Mount: Paramount ME
Camera: SBIG STF-8300M
Filters: Astrodon Gen II LRGB, 5nm NB
Guiding: Lodestar/OAG
Focuser: Starizona Microtouch, FocusMax 4
Image scale: 0.966 arcsec/pixel (Drizzled up)
Exposures: 16x900s R, 10x900 G, 7x900s B, 19x1800s Ha, 8x1800s Oiii (21.75 hours)

Scope: RCOS 14.5"
Mount: Paramount ME
Camera: SBIG STX16803
Filters: Astrodon
Guiding: SBIG RGH
Image scale: 0.55 arcsec/pixel
Exposures: 8x900s + 4x1200s R, 6x900s + 9x1200s G, 6x900s + 6x1200s B, 24x1800s Ha, 19x1800s Oiii (32.83 hours)

All processing in PixInsight.

Constructive criticism appreciated

Cheers,

WOW!! what a great image Rick, I don't think i've seen this object before.

50 odd hours has delivered the goods

Well done,

Geoff

A stunner Rick. Masterful processing as always.

I take it the TEC mainly.provided the stars?

Interesting and unique object! Very colourful. Must be faint with 32 hours.

Thanks, Geoff!

Thanks, Greg. The TEC data was at an image scale of 0.966 arcsec/pixel, so drizzled x2 it matched the RCOS at 0.55 arcsec/pixel pretty closely. I was able to use NB and RGB data from both.

Thanks, Kevin. It has very low surface brightness. Even with the substantial integration times there wasn't a lot of signal to work with.

[Placidus (Mike and Trish)]

A very evocative image. A white dwarf shuffles off its mortal coil, cape, petals. The beautiful but distant background galaxies emphasize the loneliness.

You must have been well below the one photon per minute level. Any idea of the actual surface brightness?

[topheart]

A wonderful image....awesome stuff at every level.
Cheers,

Really nice job Rick, love the saturation, everything just pops and stands out nicely

[Andy01 (Andy)]

Wow, you don't see images like that every day!
As Spock would say - "Fascinating"...
Well done on the obscure target selection & resulting image

[alpal]

Hi Rick,
that target is so dim I'm surprised you picked up so much signal.
mag 14

I think the result is a little over saturated but other than that it's a fine image.

cheers

A stunning image of this pretty faint and obscure planetary nebula Rick!

Thanks, M&T! I can't find data on surface brightness but a very rough, and possibly wildly inaccurate, back of the envelope calculation gives a result of 24 mag/arcsec^2.

Ta, Colin. Wasn't sure if I'd overdone the saturation and I'm sure some folks will find it too gaudy

Thanks, Andy! I have some even more obscure ones on the list but they take a lot of imaging time.

Thanks, Allan. I've seen it quoted as mag 17 as well. Only an order of magnitude difference

I agree that I'm pushing the limits of good taste with the saturation.

[Slawomir (Suavi)]

As always, a lovely image Rick. I agree that saturation could be a tad lower, but for the stars only.

Very inspiring image

[strongmanmike (Michael)]

That's a real beauty Rick, a really cool looking object, lots of work too, well done ...wonder what it is listening to maybe this... Two Pavarottis'? ?

[Martin Pugh]

A cool object Rick nicely presented....I agree about the saturation, perhaps just back that off a little.

cheers

Ta, Mike. Dunno if two is better than one when it comes to Pavarottis

Thanks, Martin. Seems to be a common view so I'll wind it back a little... except maybe for the FB/Flickr version - the hoi polloi love oversaturation

[multiweb (Marc)]

That's a cool shape. Nice one Rick.
