Another couple from BSG

[multiweb]

Still have stacks to process from the couple of nights I spent at BSG.

This one is from the same scorpius widefield but oriented the other way so instead of East to West this is South to North From M8/20 to M17/16 through to LBN72.

There's a much bigger one here (http://www.astropic.net/astro/M8_M16_rgb_ff.jpg). [7MB]

Why LBN72? Well John G. was imaging the snake Nebula at the time and that was looking pretty hot on his screen. He told me it was Barnard 72 as in B72, so I thought no worries, I'll check out the Gemini. Found LBN72... ermmm... Large Barnard Nebulae :question: bah...close enough. Started shooting and checked the first few subs. Funny I didn't remember M16 being even close to the snake. Anyway I kept shooting the 10 subs on it then moved toward M8 then found the snake eventually. Now you know how I plan my mosaics. :P

Great planning and great looking mosaic Marc.
Lots to see in this one :)

Awesome Marc. Just awesome.
I love these widefield Mosaics.

Beautifully done with fabulous colour. Only silly comment is it seems Lagoon is upside down? Would it look better oriented the other way? You get accustomed to certain objects being presented in a certain orientation. Neither right nor wrong just what I'm used to.

Thanks Martin. :thumbsup: I'll see if I can platesolve it as well.



Thanks Greg. :thumbsup: Yeah you're right. I stitched M17/16 panel which is the righ way up so the lagoon is now upside down. I should lodge a complaint with the galactic council. This part of the milkyway is very messy... Half baked job. Not very consistent in orientation. :P ;)

[RobF]

Really nice stuff Marc.
Love the golden colour of the milky way you have there :thumbsup:

[atalas]

:lol: real funny Marc! hey,sensational work dude.

[desler]

Good stuff Marc! Swim around in there for ages!

Lovely result Marc!

Great Image scale. Almost can't recognise Swan and Eagle at that scale. :)

Nice colours. You have that rich gold colour in the Sagittarius Star cloud, not over-processed to make all the stars look white.

Well done. :thumbsup:

[Big Dave]

Nice Pic. wasn't the weather Fab this year.

I still have another 4 more objects yet to be processed from that week, just over it at the moment.

[JohnG]

Good one, Mark :lol:.

Like your results so far :thumbsup:.

Cheers

[CoolhandJo]

Wonderful wide field.

[dj gravelrash]

awesum--jealosy really is a curse lol

[TrevorW]

In all honesty a really nicely composed image with bundles of detail, the only thing I find distracting not only in this but other similar widefields is the diffraction spikes appearing on the stars due to the lens used, apart from that really well done.

[John Hothersall]

That is a splendid field of the richest area in the sky with so many objects displayed, the small dark spot next to M24 star cloud caught my eye.

Hi Marc,

Another amazing photo.

I can't get enough of your colours and detail.


Thanks.

Ross.

[LucasB]

Beautiful seamless mosaic! Well processed.

This is a very nice rendering of this area. What gear were you using Marc? Am I right in thinking something like a 14mm or so lens on a DSLR?

[iceman]

Beautiful result Marc, I really liked that.

[multiweb]

Thank you Rob. :thumbsup:


Thanks Louie. :thumbsup:


Thanks Darren. Glad you liked it. :thumbsup:


Thanks Ken. :thumbsup: Yeah at that image scale it's sometime hard to pick up the little details especially with the QHY8. The swan is still ok. The Eagle doesn't show any pillars. The 9 would pick this up though.


Thanks Dave. :thumbsup: Yeah the skies were terrific. I'm still going through a backlog of stuff myself. Nearly there. :)


Thanks John. Catch up soon in Nov. :thumbsup:


Thank you Paul. :thumbsup:


Thanks m8 :)

Thanks Trev. :thumbsup: Yep I don't really like them either but I have to stop the lens down a bit so no choice. Until I get better at it and find another way to do it with circular aperture rings. All part of the fun. ;)


Thanks John. :thumbsup: Haven't manage to platesolve that one yet. Will check it out.


Thanks Ross. Catch up soon. :thumbsup:


Thank you Lucas. :thumbsup:


Thanks Paul. :thumbsup: This is the same rig I use with all the shots I did at BSG including the barnard loop. It's a 100mm lens. SMC Pentax-M 100mm f1:2.8 stopped down to 5.6. I used a Baader fring killer in front of the lens and a Baader UV/IR filter at the back. It helps with star bloat and also color fringing. The camera was a QHY8 and the whole thing was guided through a GSO finder with a QHY5/G11. These are two panels of approx. 13.6 x 9.0 overlapped over the star cloud. Whole field South to North (left to right) would be about 26.5 x 9.0 degrees.


Thanks for the comments Mike. :thumbsup:

Nice result Marc, yet another wide field mozaic feather in your cap, as for being upside down..?.. I kniht s'ti kcab ot tnorf :question:

....is that M8 I see in there too :eyepop:

Mike

[marco]

Very nice Marc, I love these wide field mosaics! Which software did you use to stitch the panels together?

[midnight]

Marvellous and a lot of effort has gone into that Marc so well done!!

Darrin...

[midnight]

Marc, you seem quite happy with the Baader fringe killer. Would you recommend one for DSLR work (50mm to 200mm FL stuff I'm planning)?

Really having trouble with the stars beyond 85mm.

Cheers,
Darrin...

[multiweb]

Thanks mate. :thumbsup: ermm... M what? :scared3:


Thanks Marco. :thumbsup: I register the panels with registar then use the auto blend feature in PS CS5.


Thanks a lot Darrin. :thumbsup:



Yes - definitely. And a 2" is not expensive at all ($70 or so) compared to other nebulae filters or even narrowband.
UV/IR will stop your star bloating. The finge killer will get rid of the purple or blue halos around your stars. A must if you use any lens (or refractor) with a bit of chromatic aberration with a one shot color camera. If you have a mono it's not an issue because you can focus the color separately, but with a DSLR, yes go for it. It's a not brainer.
