Jellyfish nebula with OSC camera

Recommended Posts

I get a bit of a kick out of dragging as much out of minimal data as possible :)

Took this last night, packed up early though as it was getting icy and treacherous. I think by the time I packed away it was -5c.

Anyway this one actually came out better than i expected and i'm pretty pleased so far :)

55x120s stacked and processed primarily in APP and final touch up in Photoshop. Also used my L pro max filter for this, which no doubt helped.

Its a beautiful image done with a OSC - may I ask what camera and telescope please? Also not an easy object to image.

Of course :) thanks for the great feedback also. 

I use an Altair 72edf deluxe scope with lightwave 0.8x reducer and Altair hypercam 183c Pro Tec (gain 400, -15c, black level 30)

Looks like it might be clear in my neck of the woods tomorrow, so i may go for a bit more data on this....or maybe i'll go for a different target. Decisions!

Really nice,  maybe it’s just me but I think the focus is just a tad off....  just constructive criticism :)

Thank you . Nope focus was smack bang on as I regularly checked my focus :) I do believe the issue here is with my processing. Probably something to do with the fact I did it at 3am . I never learn ??

I think I may have used dust and scratches a bit too much and also had the opacity on that layer too high...so it became more fuzzy.

Yes that could be it, if you zoom in it’s very fuzzy and noisy...but very good all the same.. :)

The composition of this image is superb - the use of the surrounding stars to frame and accentuate the Jellyfish has been a big success!

The colour combination of the stars and nebulosity works exceptionally well.

Putting this jellyfish back in the pond now! had enough for this season, but its been a useful learning tool!

IC443 - The jellyfish nebula. A Supernova remnant in the constellation of Gemini.

143x120s. Altair Astro 72EDF Deluxe, 0.8x reducer, Hypercam 183c Pro Tec, HEQ5 pro.

Stacked and processed in Astro Pixel Processor, with some hefty processing in Photoshop too.

 

 

This one has been a pita to me ...I so wanted to call it finished but couldn't leave it alone. Finally happy with this version now!

Very nice, the version above seems to have more detail and nebulosity showing, yet I assume this is more subs..any reason for that... :)

Yep! Just to increase the SNR. More darks and flats didn't help the previous version ;)

But surely it should be at least the same detail wise, the nebulosity on the left has almost gone....or am I missing something...?

This turned out really well ?

Great to see it evolve like this - we all go through that pain - you finish it and think "That's what I wanted it to look like"....then the next day you look at and have another try at other adjustments.

Like  you said excellent learning process, and you've wound up with a great picture for your gallery ?

It's a different process, this time I focused on the jelly fish nebula itself and not the rest per se. I didn't want to 'overcook' it this time whereas in the previous version I felt I did to keep the area on the left. Everything is a balance...im quite happy with my latest and final version

Thanks so much David . This was a challenging target for me as really I am still a beginner compared to some folks on here :) for example, it was only on my latest session on the jelly fish (14th Feb) that I carried out a meridian flip for the first time :)

This is a massive improvement on your original processing and a nice image on a dim target from a light polluted area.

I keep wondering if ill see you post a image using the Ha filter I sold you. Blending some Ha in with the red channel of this image would work really well.

That's the plan eventually ! :) I found focusing manually with the Ha filter difficult....so I've got a Sesto senso for my birthday (in less than a month) then I hope I'll be able to focus easier and make use of those filters! Cant wait. Thanks for the good feedback also :)

      Hi Everyone,
      This is my first NB image - 16x600s of Ha plus 16x600s of Oiii - Sii will have to wait for another long, clear night.
      I went with the blended channels approach in PixInsight 100% Ha in R, 40% Ha + 60% Oiii in G, and 100% Oiii in B. Using 100% Ha in R and 100% Oiii in G and B resulted in a very red nebula and a distinct red tint to the background.
      Any help or suggestions on how it might be improved would be much appreciated - I essentially followed the LVA tutorial.

      Thank you for looking.

      This is an LRGB image with Ha blended in the Lum and Red channels.
      The Lum was quite faint, even after over 3hours, so I decided to blend quite a large amount of Ha in order make the image reasonably bright and not too red. The Ha is also blended into the Red channel but at a much lower level.  I made a slight change to the Hue, towards the green, in order to get a slightly more appealing red.  In total, the image represents about 13 hours integration time.

      First a slight aside: I quite like trees but they can be a bit frustrating when you have a target object (eg IC443) that is visible for a couple of hours, disappears behind trees for a couple of hours, reappears for a couple of hours and then finally disappears. To overcome this I've programmed ACP with my highly undulating horizon so my scope acquires other objects when others are hidden - the joy of automated imaging...
      Anyway, back to the image which represents about 13 hours of integration time - I decided to go for a LRGB image with an Ha blend in both the Lum and Red channels. I was surprised that even with a relatively long exposure on the Lum it didn't pick up more of the nebula,  so I decided to blend a higher than my normal Ha percentage into the Lum so that it would appear reasonable bright and not too red.
      Alan

       
       LIGHTS: 20; R:10; G:10; B:19 x 600s; Ha:7 x 1800s. DARKS:30; BIAS:100; FLATS:40.

      Now, when I finally have some clear skies, the moon spoils it all, so I have played around with data from last month on the Jellyfish Nebula. It is my DSLR data with Francois Theriault's CCD Ha data as luminosity.
      Equipment in Sweden: ES 127ED refractor with TS 0.79x reducer (=f/5.9) IDAS filter and Canon 60Da on EQ8. Equipment in Canada Antares 8" Newtonean (f/5) and SBIG ST8300M and Bader Ha 7nm filter on CGEM.
      65 x 300" exposures = 5.4 hours

      After my last attempt at HaRGB on the Horsehead, I have decided to concentrate on narrowband for now from my semi-urban home.
      I have had a go at the Famous Jellyfish Nebula in Ha with my trusty 150 pds and SBIG 8300m with the Baader 7 nm filter. After looking at the efforts of others on varying targets, I have come to the conclusion that even narrowband benefits from darker skies!
      16 X 1200 seconds.
      Processing was mainly just stretching in PS, but I had a go at the mure de noise script in PI first, as demonstrated by Gnomus and Barry ( https://stargazerslounge.com/topic/262808-another-rosette-wo-star-71/ ).
      I still think it's a little waxy, but not excessively so, and it did allow me to stretch it that little bit more before the histogram turned into a profile map of the Dolomites ;)
      This might be my last with the 150 pds for a while as I'm off to Essex to collect a WO Star 71 today!!
