IC 410 - The 'Tadpoles' in bi-colour

Recommended Posts

I have finally managed to collect sufficient OIII data to produce my bi-colour version of 'The Tadpoles', a nebulous region in Auriga. This has not been an easy task as the skies have been most unhelpful and it has taken several nights for each channel often gaining less than 5 subframes at a time! The majority of the Ha was captured under moonlit conditions where the very narrow bandwidth came in very useful. I still have work to do on the stars but will wait now until I have some SII data to complete an HST palette version.

Brilliant.  Who needs a remote observatory in Spain (with apologies to Barry Wilson......) except of course for the weather and the seeing.  Well, I am surprised that 23.5 hours took more than just a couple of nights at this time of year......

Nice crisp nebula and tadpoles - it's almost 3D.

Fantastic image, well done considering the difficulties. Can't wait to see the final result after you've played more with it.

I knew it would be worth waiting for :icon_biggrin:.

Excellent Steve - framing, composition and characteristic sharp delivery.  It's not always easy to show tonal relief between the contributing Ha/OIII and you have a lovely contrasting colour palette showing the Tadpoles well with a splash of blue at 'their'heads'.

Top drawer.

Such is the joy of imaging in the UK.

Thank you, Barry - I was pleased to see the 'tadpoles' themselves pop out with the application of the OIII to the original Ha data and that gentle blue halo was a real bonus.

Well done Steve.

Being only 4miles apart I know how hard it is imaging in our neck of the woods. :icon_salut:

It hasn't been great recently, Mike, has it? :D

It's a great pity that I can't persuade my wife to move to France, learn the language and go native! Mind you, I'd miss my sons and grandchildren too much so I am also part of the problem! What is great about imaging from the UK is that the satisfaction when the weather does play ball makes you forget all those wet and cloudy nights .... that said, have you stepped outside this evening? Yuck .......... :(

Sure have and quickly came back in.:icon_biggrin:

Sometimes dream of a nice dark spot, yes, South of France would be nice and steal some of Mr Penrice's photons. :wink::icon_biggrin:

Although this has been my best ever year imaging.
Real glad I got the CCD it's allowed more imaging than the last 3 years.

I suppose what they say about these nebulosities being the birthplaces of stars, etc. is true. This reminds me of photos in anatomy texts that show sperm trying to penetrate an ovum to fertilize it. Life on a grand scale.......

Looking great Steve, will be interested to see how much added value you get from the SII (I've become a sceptic!).

On the night of the 18th December, I did manage to collect some SII data from this object - a whole 6 x 1800 seconds worth of it but I wasn't too impressed with it. However, another opportunity did not arise and I moved on to other objects but this morning, I thought I would give processing the SII data a shot just to see what effect it would have and the result was pleasantly surprising. The stars have a better, albeit more bland, appearance but the addition of the SII data has perhaps added something to the overall image and dramatically changed the colour balance as one would expect!

I like that Steve - The SII has really accentuated the 'glowing' around the tadpole heads........ I think that it really is worth persevering with a three channel approach. When I think I can't be bothered and process a bi-colour, the SII always seems to add something more 3D when I can be bothered to add it!!!

Wonderful as the HST image is the question for me is, what would the image be like if all that SII time have been spent on more Ha and SII?  I'm still liking that bicolour!

It's a difficult balance for me here in the UK. Bi-colour saves a third in capture time but adds at least that back in at processing time to get some god colour saturation BUT I can process when it's cloudy!

As above, a difficult balance. the HST image does have more punch but at the expense of subtlety!

      Hi guys
      First things first, apologies for posting this one out of season. A combination of no astro dark, crappy weather, and being busy at work has meant that there's no imaging getting done at all these days. So, i've had to turn to old data to re-process, and this data set was an obvious candidate as i was never happy with how it came out originally. And looking back on it now with fresh eyes, boy did it need it! 
      Nikon D5300, SW 80ED, HEQ5-Pro. 
      3 x 1200s, 2 x 1380s, and 4 x 1500s of Ha
      9 x 1200s of Oiii. 
      11 x 480s with an IDAS-D1, for RGB stars only
      7 Hrs 54 Mins in Total. 

      Stacked in APP and processed in PS. 
      Combined as SHO (using a 70/30 blend of Ha/Oiii for the Sii). 
      The main differences this time were, using Starnet++ to create the starless versions, using more Ha in the synthesized Sii (70% instead of 50% last time), but mostly the improvement has come from toning down the stretch a lot (ok, a heck of a lot!) before making the colour map for the tone-mapping. From then on it was immediately apparent that i'd made a massive boo-boo first time round 🙈
      I've included a 1080p rotated crop too, as i quite liked the framing.
      Feels like ages since i last did any NB imaging. I almost forgot how much i enjoy it! 🙂 


       
       
      And rather embarrassingly, here's the original. Try not to laugh too hard! 😂 😂 😂

      Hello Astro Peeps, I hope everyone is all good! Isn't there some amazing images on this site and others. Amateur imaging has never been so good!
      I myself have finally managed to get some data for an image, of which I am very happy. It has been so hot here it has been impossible to get any good data. One day a couple of months ago, I hung the thermometer from the grape vine under the back verandah and it was 47.5°C. Sounds far fetched, although true. I live in Adelaide, South Australia and we are 11km from the CBD and usually 1.5 degrees hotter than there!
      Anyway, I thought I'd try my hand at a Ha, OIII bi-colour image while waiting for my SII data to come in. There seems to be a halo issue with some of the filters for which I will need to do further testing so I apologise for their distracting nature. Details are with the image but basically 3hrsx15min subs for each channel.

      Hi guys
      After processing the Eastern & Wastern Veils separately a couple of months back, I've finally got round to doing the mosaic that was always the end goal (hence the framing of each panel). I'm not sure why I waited so long to do it, I think deep-down I was secretly dreading it really, as this is my first mosaic so I wasn't really sure how it would go.
      So this is just 2 panels, and each one has 5 hrs of Ha (15 x 1200s), with 3 hrs 20 mins of Oiii in one (10 x 1200s) and 3 hrs 40 mins of Oiii (11 x 1200s) in the other. So 17 hrs in total.
      APP was used for stacking, gradient reduction, and the mosaic creation. PS used for everything else.
      Ha assigned to Red, Oiii to Blue, and Green was synthesized from one of Carboni's actions.
      I've tried to push it as far as I dare to, did I over-do it do you think? I've resized it down to 66% to help hide some of the noise, and being a mosaic it's still plenty big. I might even end up bringing it down to 50%, we'll see.
      C&C welcome as always. I tend to finish my images very late at night, so I can sometimes fall into the trap of not seeing the image as clearly as I should! So feel free to be as harsh as you like ?

      Hi guys
      We had a few hours of clear skies here on Saturday night, so I set about getting some O-III for the Western Veil, after I had collected the Ha last month. Thankfully, the moon wasn't around, so even though I didn't get that many subs (only 10) at least they were of good quality.
      I actually fell asleep during the capture, and woke up to a 'Sequence Aborted' message in SGP and the sight of PHD2 going mad due to thick clouds. Quickly ran outside and thankfully there was no rain about (phew!). I got 11 subs in total, but the last one was totally unusable due to the clouds. The 10th one was affected too, but still looked useable to me, given that I know from experience that APP's 'Quality' stacking mode would know to give it less of a weighting, so I kept it.
      So this is 15 * 1200s of Ha and 10 * 1200s of OIII (8 Hrs 20 mins in total).
      Taken with the usual gear: Nikon D5300 (modded); HEQ5-Pro and a SW 80ED.
      Calibrated with Flats, Bias, and a Bad Pixel Map. APP used for stacking and gradient reduction. Everything else done in PS (including running Carboni's 'Synthesize Green Channel' action).
      After now having processed both the Eastern & Western Veils, I have to say I have found them to be among the hardest targets to process that I've done so far (although it's still early days for me yet, think I'm still under 15 DSO's and counting). I'm not sure if it's down to the sheer number of stars, or the very faint nebulosity that seems to be everywhere, but I've found the background to be especially difficult on these ones. Getting the Ha and OIII nicely balanced before combining probably has something to do with it. I also tend to do gradient reduction (which seems to affect the OIII a lot more than Ha) on the individual stacks before I combine them, so I wonder if I'd be better just leaving it to later in the process? (which I had to do again anyway, as there was still a noticeable red gradient visible later in the workflow).
      Something to note, I did go quite heavy on the star reduction. More so than I normally would. I found it wasn't until I upped it significantly, that the nebulosity really started to take centre stage. I like the impact it has made to the image overall, but it made me feel a little dirty at the same time, lol (if that makes any sense).
      Also, this isn't actually the finished version just yet. I have a bit more work to do on the background and stars (which need their colour toned down in places - probably shouldn't have ran Carboni's 'Increase Star Colour', in hindsight I don't think it needed it). I was literally falling asleep at the monitor last night while attempting to finish it off, and in the end had to admit defeat. So hopefully I can get around to it later tonight.
      Then the next thing will be the big mosaic of both Eastern & Western Veils. I'm both looking forward to, and dreading it, in equal measures ?
      As always C&C warmly welcomed!

      Having acquired an ASI 1600MM Pro earlier in the year, this is my first attempt at a wide field Ha/OIII bicolour, using a Borg 55FL scope.  15 x 240s Ha and 15 x 240s OIII, integrated and combined in APP and edited in Star Tools.  I assigned Ha to the Red Channel and OIII to Blue and Green, but would be grateful for any tips on combining channels for bi-colour images. 
      I  also tried combining with the LRGB Tool in Star Tools, assigning Ha to Red and OIII to Green, allowing STar Tools to synthesise the missing data.  The result was interesting, but did not produce the 'traditional' Red/Cyan colours of this target.
       
      Apologies, maybe someone can advise how I can insert the image into this post, rather than have it as an attachment please?
      Cheers
      Dave
