Hi all,

Serving a cooked Lobster - SHO flavour.

Caught with 105 mm refractor at f/6, ICX814 and 3nm Astrodons.

It appears to be my longest acquisition to date - exactly 32 hours.

That's most excellent, Suavi! Hope you're going to submit it for the AAQ Astrophoto comp :)

In your face impact!

Thank you Rick for your kind feedback. I shall email the image tomorrow after work.



Thank you Colin - looking forward to your interpretation :)

I decided to keep my original Ha and just did a touch of noise reduction on starless SII and OIII and played with curves and histograms.

I'm gonna call that DRAMATIC!

That's a superb image Suavi and the nicest image of the Lob I have seen.

Wow, that's impressive! Very fiery look to it.

How did you get 32 hours in Proserpine? Edit, I forgot one can shoot narrowband in moonlight.

Dramatically spectacular!
Original and pleasing to say the least!

Thank you all for your encouragement. There is plenty of room for improvement (I eagerly await Colin's interpretation of the Lobster) but the overall result is not too bad, given the moon phase, thanks to 3nm Astrodons, the mount and SGP that flawlessly did meridian flips and looked after collecting data over several nights while I was asleep.

Maaaate! :bowdown: This is utterly superb! Sure the core is bright but it's a case of M8/Hourglass, M42/Trap. You've still got the whole dynamic range down pat and it's relevant to the fov. I particularly like the Oiii regions with the overlapping Sii/Ha. Very reminiscent of the Rosette nebula. Best I've seen of this object. Kudos to you. :thumbsup::thumbsup::thumbsup:

Well done Suavi :thumbsup:
You have shown the three wavelengths well, and processed it beautifully.

From experience there wasn't much O3 present, so you've brought what's there nicely into play. :)
It has a sinister brooding look to it which I think suits this object well.

At risk of playing Devil's advocate though, imo it's still a bit soft. Not out of focus soft, but lacking defined edge transition. Notwithstanding others earlier comments about whether or not that's "real" :D
Now if you're after a soft ethereal look then that's totally ok too - but this subject has dramatic cocoons, gas pockets and shock fronts that present skeletally, which imo lend themselves to a more 'defined' result.

Moving on, your colour palatte choice is sublime and it's a top shelf image, very well done! :thumbsup::thumbsup::thumbsup:

That's a delicious looking cooked lobster! Amazing depth. :thumbsup:

Great picture Suavi,
That CFF 105mm is working really well -
you have perfect tight stars from corner to corner.
Is it the oil spaced version?
Anyway - your scope seems to be performing at least as well as more well known premium scopes.

cheers

An all round excellent image Suavi, colour (all three!), detail, general processing, framing, everything, all really nice, well done mate...worthy of another bridge that :D :thumbsup:

Thank you Marc for your encouragement, and yes, I agree, the core is quite bright but in the end I have decided against compressing the data.



Glad you like it JA.



It does look quite...intimidating :lol:



Thanks Andy. Yes, there wasn't much OIII so it took a bit of experimentation to bring it up. There are no doubt a few things I could have done better and I was also initially thinking of adding RGB stars, but I am ready to move on to another project :)




Thank you Pete :)



Thank you Allan. Yes, it is an oil spaced triplet and it is quite sufficient for me at this stage :)



Well, that bridge projection with he photo of the dragons was just a fluke, but I'm glad you like this image Mike :)

Normally I'm not a fan of seafood, but I totally love this!! :-)

Hi Suavi,
wow - I have always been under the impression that
oil spaced triplets are the best.
There is much evidence for that on the web:
https://www.baader-planetarium.com/en/blog/apochromatic-triplet-objective-why-oil-spaced-lenses/

A friend of mine had a long f ratio oil spaced doublet &
claimed that he saw the best views of Mars with that
compared with any other telescope he'd ever used.
He wished later that he'd never sold it.


cheers
Allan

Wow, thats superb and you now definitely have a 'Suavi' look, to be copyrighted!

That's a truly magnificent image Sauvi.
Congratulations!

I have certainly been impressed each time I looked through this oil-spaced triplet. Sometimes I think an additional 120-130mm one would be very nice for visual pursuits.



Thank you Louie :)



:lol: Thank you Simon.



Glad you like it Jeff. Now I am quite happy that I went against my mind and took advantage of clear nights during the full moon.

Thank you Markus. Seafood can be quite tasty when cooked well :)

Great to see you back at it again, Suavi, and with a nice deep integration! Very dramatic presentation! Looks sensational when viewed at a scale such that it fits my display. When pixel peeping it does look a bit overcooked to my eye, but I think I tend to understate things a lot when compared to many others.

Wonderful.

You've shown the location of the SII very well. An area of much turmoil.

As one who can't help seeing evocative sub-images, I've always found this a very disturbing part of the sky, full of skulls and ribs and other nasty bits and bobs, with the only redeeming feature being a very obvious Border Collie sitting happily in the exact centre, if you rotate the image 90 degrees. Your careful processing, subtle touch and wider field have made all that turmoil and fine detail look like a lobster again.

Very best,
Mike

Thank you Lee. Yes, it is a great feeling to be able to make a contribution to the DSO section on IIS after my prolonged absence. Perhaps one day I may tweak processing a bit, but at this stage will leave it as is.



Thank you Mike. I generally tend to be very cautious with noise reduction/sharpening/highlighting features and stay away from decon altogether, but when it comes to colours, I can, at times, overdo things just a bit :lol:


EDIT: I have just "found" this fantastic image of the Lobster on Astrobin: https://www.astrobin.com/full/350894/0/ Now, that is a benchmark!

Now all you need is a 20” F/3.8 Newtonian and a 16803!

And place it on a site high in the mountings in Chile - like in the below mentioned image.
