About 11h Sii, 8h Oiii and 5h Ha with a SMC Pentax 200mm at F/5.6 and a QHY9 on a G11. Full res is here (https://public.bay.livefilestore.com/y1p5ZtQnIMhxZ85LW-sqAEdXxu3aoDa3JIrOL1SIrvCrc6GyCKDac 6gHDSf5HzLRyrtk88yy3wGt0vWhSMmnH4Wp A/Scorpius_SiiHaOiii_fl_fff.jpg?psid= 1) [1.5MB].

I love it Marc, but......



Shhhh! :lol:

Wow Marc that looks amazing and the large version is awesome! Great colours and FOV. The cluster seems to lie right in the centre of a big bubble. Thanks for the view.

I've had to come back and look at this image a few times. I wasn't sure about the colours but they have grown on me :thumbsup: It's a very interesting image, Marc!

[stevous67]

Absolutely beautiful Mark - congratulations and well done! A lovely scene to search through.

Steve :thumbsup:

[DavidTrap]

Way cool - I'm loving all this NB stuff that's being posted! I've been getting my "urban setup" sorted over the last couple of weeks and will be hoping to do something similar in due course.

And a great effort It is Marc.

[Paul Haese]

A nice looking image with lots of cool colours. The cluster does seem to have blown off all the gas and pushed it away.

Thanks. But.... :question:


Thanks Rolf. :thumbsup: Glad you like the higher res. Yes that's what I noticed too at first. I asked a few people about this actually because I couldn't find any NB version online that wide.


Thanks Rick. :thumbsup: It's understandable and it took a little while to grow on me too.


Thanks a lot Steve. Glad you liked it. :thumbsup:


Thanks David. :thumbsup: Yes give it a shot by all means.


Thanks a lot Louie. :thumbsup:


Thanks Paul. :thumbsup: Yes I was reading this cluster is made of very hot young massive stars apparently so may be the whole front/bubble is related. I don't know if it lays in the same plane as the rest.

Amazing view Marc, thanks.

[RobF]

Top stuff Marc. I'm not sure about the aesthetics of the colours, but heck, knowing how hard NB is to bring together will just tip my hat :)

[DavidTrap]

Marc,

Can you please tell us what length exposures you used for the 11:8:5hr combination?

I'm taking a punt that the oxygen & sulphur exposures were longer?

If so, is there a way of "balancing" the exposures like a G2V star, or does it relate to QE of your particular sensor?

Thanks Lester. :thumbsup:


Thanks Rob. :thumbsup: Yes, not your typical HST look. I guess the wider the field and sandy milkyway textures turn to deep pink or reddish if they're blue or yellow starfields.




Hi David, Sii where 30min exposures, Oiii 20min and Ha 10min. I had to go longer with Sii and Oiii. I kept increasing exposure time to get a better SNR. I actually did well in excess of 48h on these after a lot of trial and error, guiding problems, wind, seeing issues some nights. But in the end I picked the best subs. As far as color balance goes I usually do a pixel math to match all background ADU to the brightest channel then extract the colours in photoshop. I try to stretch each channel equaly and process the way I'd do an RGB shot. I also try to get rid of the greens but I always leave a bit in there as I don't like NB shot with just red/blue and brown.

[MrB]

Oh haha, just hinting not to spread the word too far about the SMC glass ;)
My first SMC Takumar cost me $10.... try getting one for that price now! :eyepop:

[multiweb]

Ha... :lol: Yeah. That 200mm lens cost me $60.00 inc. shipping from eBay.

[MrB]

Nice!
I got the SMC Tak 105/2.8 for $100, I love it.
Still trying to get a 135/2.5 for a decent price, and trying to get a mint Tak 85/1.8 for less than $300... thinking to go for a Samyang 85 instead :(

[Stevec35]

Very nicely done indeed Marc

Thank you Steve. :thumbsup:

[Jeffkop]

Totally agree with all before me .. Great result in narrowband ... Now that is the next level I reckon .. I really like it.

[Ross G]

I'd say that's just about a unique shot Mark :question:

Looks great, especially the lovely dot like stars :thumbsup:

Mike

[RickC]

wonderful image Marc

cheers, Richrad

[allan gould]

Excellent image as usual Marc. Love the colours and composition.

[multiweb]

Thanks Mike. :thumbsup: Yep, colours are certainly unique. :P Stars look good though after throwing away hal of the subs.


Thanks Richard. Catch up soon :thumbsup:


Thanks a lot Allan. :thumbsup:

Thanks for looking Tom. :thumbsup:

[CoolhandJo]

Lovely. nice framing - NB colours look spot on to me! :)

[gregbradley]

That's way good. Its hard to imagine you used a lens. It looks more like an FSQ image.
You've got that lens well under control.

Greg.

[multiweb]

Thank you Paul. :thumbsup:



Thanks Greg. :thumbsup: An FSQ106... I wish. One day I'll get one. When both kids have finished UNI and I sell and move out of Sydney somewhere dark. :stargaze:
