PK 164+31.1 - Planetary nebula in The Lynx

Recommended Posts

PK (Perek-Kohoutek) 164+31.1 is a planetary nebula in the constellation Lynx.  It is also known as Jones-Emberson 1.  The nebula is some 1600 light years from us.

This is Ha plus LRGB captured over several nights from the DSW facility in New Mexico on the Tak 106/QSI683 rig 

  • Luminance: 18x900" bin 1x1
  • Red: 14x900" bin 1x1
  • Green: 17x900" bin 1x1
  • Blue: 16x900" bin 1x1
  • Ha 5nm: 13x1800" bin 1x1

Another object I think I will revisit in my Esprit 120.

So are these images not taken at your home obsy with your own kit, but a remote site set up...is it one of those imaging set ups you can hire online..?

Hi 

I do have a home imaging observatory (two, in fact), but this is data from a remote hosting location in NM.  I have subscribed to one of the 'teams' for 12 months.  I get to choose targets (as does everone else on the team), but I get all data from that scope for the 12 months - so people get the data from 'my' target and I get the data from everyone else's target.  There are other remote operations that do allow you to 'rent' time on the scope - look for 'itelescope.net' (I think) - but I believe that the data that you get is exclusively yours (I could be wrong about that).  I haven't used them so cannot comment.

I was finding that I was not getting enough data to satisfy my hunger.  It is certainly a good way of getting data (which can be hard to come by in the UK even with a permanent set up) and therefore getting vital processing practice (reprocessing the same data again and again was become a little stale).  

There has, however, been a long discussion about this here: https://stargazerslounge.com/topic/290262-uk-imaging-vs-remote-site/ which revealed that some folks take the view that what I am doing is 'not cricket' - even to the extent of calling it 'cheating' - https://stargazerslounge.com/topic/290262-uk-imaging-vs-remote-site/?do=findComment&comment=3183463

+ great image btw. Do you have access to longer fl optics in NM as well?

Thanks Wim.  There are longer focal length scope teams.  I'm just on the Tak 106 rig.

Is that the Key hole nebula?  If not--looks like a key hole.  A faint [removed word] I bet.  Great processing.  The idea of getting more data is appealing--I did not know that you get all data for the scope for the month.  Depending on the cost, it sounds like a great way to process--lord knows practice can't hurt!  Because you get all data, you probably are not as upset when bad subs are identified, or bad calibration.  If you pay for only your subs, bad ones would mean allot more.

It ain't cheating.You said up front exactly where the data came from.

Cracking image too!

Great image Steve!

Regarding DSW data: For all of us that are not retired persons with their own obsy on a desert mountain somewhere with eternal clear skies, I see sites like DSW as a really great option when you have this processing hunger like Steve (and I) have. I cannot see it as cheating. Rather the opposite. If you have your own obsy with your own data, you can always blame the sky and the equipment for imperfections. But if you are as brave as Steve is and post these DSW images, you cannot do that since a bunch of other AP nerds have the same data and can easily prove him wrong by posting much better versions of the same data (not that I have seen that done in Steve's case). If I go for DSW, that would be a slight worry, but not a big one since I am new to this game and have no pride yet.

Still, this makes me curious. Steve, it must be with some nervous anticipation that you look at astrobin and other sites to see what your fiends accomplished with the same data?

Yes.  This astrophotography business can be devilishly hard sometimes.

I've always wanted to image this. It's a glorious object and you've done it proud here.

I also take a strange delight in the name, Jones Emberson One. That long first vowel in Jooooones. It puts a smile on my face. I should see a psychiatrist.

you guys can be so serious :):)

Don't worry - we know.  The chaps posting are veterans from the other thread.  Not 'serious', it's more that the humour is very 'dry' - which is just how I like it.

      Hi, i..m on Stargazers Lounge for long time ago, but now i have a new scope at last!!! The scope is a Skywatcher classic200p dobsonian, and i received it just one month ago. I.m really happy with it. For now, i.m using the stock eyepieces that come with the scope, a 25mm and 10mm super plossl 52. Yesterday i was received a Celestron Omni barlow, and that expands my magnification range. I posted some pics with my set. 
      Congratulations to Stargazers lounge team, this is one of the best sites to learn about astronomy and equipment. 
      Besf regards to everybody

      A DSO image in planetary settings.
      This is the Eskimo planetary nebula. Small as they are, this one has less than 1arcmin.
      The image was taken with a C11 f10 and ASi224. No cut-off filter was used.
      The capture was made with Firecapture and 2s exposures. The final processing was in PI.

      Having seen another forum member's deep sky experiment with the ASI120MC camera, I tried the experiment myself.
      Here are e1e2 Lyrae, the Cat's Eye planetary nebula, NGC6210 and NGC6572 all imaged with a C8 SE and the ASI120MC.  The planetary inages are single image captures, while the double-double is processed from a short video stream. 
      I also tried M57, and while I could see it in purplish colour at an exposure of 8 secs, I could not get the Sharpcap live stacking to work.
      From an EAA point of view, this camera and planetaries are a definite hit, as the camera and laptop show them better than the eyepiece, and in colour.

      Well the lynx cable came yesterday for my EQ6 PRO  from FLO,well packaged in a bubble wrap bag  and comparing with my previous eqdirect cable, build wise much better, more professional looking , thicker round cable,  metal  D-sub with long thumb screws, moulded usb plug, £34 ok not cheap but about the norm for an EQdirect cable , quick check eqmod found straight off ,uses the fdti chip set so didn`t matter what usb port i used, still said com11, 
      would recommend .

      Hello folks!

      On saturday, I sent stargazing with my girlfriend at a friend's place. The sky is not too bad, but unfortunately there still is some light pollution in direction of the south.

      I was looking at NGC246 (In Cetus constellation, which was still south-east) when I asked them if they would "allow" me to sketch it. They did.

      Here is the result:

       
      I'm not really satisfied since the "right" extensions are not it the right place. I mean, the fourth star should be in the center of the "spikes" and not on the border. Better luck next time.

      José
