Orion Wide Field - from Wiruna

[AstroJason (Jason)]

Hey all,

Following on from the 200mm version I captured of the Orion complex I took from Bretti last month which can be seen here. I had another go at it but from Wiruna this time at 70mm to capture more of the surrounding dust and nebulosity in the area.

This is just 2 and a half hours of 5 minute subs, like last time, dawn stopped me getting more data. I will be adding more data to this over the season as its an incredibly detailed area.

A much higher res version can be found here.

As always feedback is appreciated and thanks for looking.

Cheers,

Jason

That's stunning!

[Geoff45 (Geoff)]

Really good Jason

[Rod771 (Rod)]

That's looking really nice. Your certainly ticking up the miles on your trips.

[cometcatcher (Kevin)]

Fantastic!

[AG Hybrid (Adrian)]

Great

[RickS (Rick)]

Nice work, Jason!

[NOMH (John)]

Love the wide field!

JB

[Camelopardalis (Dunk)]

That's a cracker mate, well done

All the dust is starting to show through, and naturally love all the "loop" and the diffraction spikes are really effective!

[killswitch (Edison)]

Wow that is wide. Top stuff

[AstroJason (Jason)]

Cheers all for the kind comments.

Yeah Rod, lots of driving which I may be repeating in less than 2 weeks time. But just glad the weather has been rewarding us for some great nights.

Yeah Dunk I love the spikes too, will miss them if I eventually do go to a refractor.

Great colour, expansive field and detail looks good but the image in the high res is only 1024 x 688. It would be really nice to see something around double that resolution.

[AstroJason (Jason)]

Thanks Paul, I did work a bit on keeping the colour in check. Click here to see the larger version which is almost double (1761 x 1184).

A beautiful widefield photo Jason.

Love the detaila and colour.

Great composition!

Ross.

[PeterEde (Peter)]

Puts my few minutes to shame. Wow

[N1 (Mirko)]

Great image. Colour is probably a bit much for my eyes, but stunning detail. I like the Rigel - Witchhead relation.

[Joshua Bunn (Joshua)]

Wow Jason, that's a lovely view and you have done a great job!

Josh

[bobbyf (Bob)]

Thats really good
I assume the saem gear was used? Canon 6D and 70-200F4
Was this at F4 or did you have to stop it down a bit?
I've tried this with an APS-C sensor at 50mm and had to stop down from F1.8 to F4 to reduce CA and coma.
Yours looks great from this point of view too.
Well done
Cheers

Many thanks Ross, glad you like the detail and colour!

Cheers Peter, yeah I am really beginning to see the benefit of having a lot of data. Really does make a difference in being able to bring out the fainter details.

Thanks Mirko, yeah I had to work a bit on the colour and I had what I thought was way to much colour in the stars. Was doing my best to control this. I really need a proper monitor screen to do the processing on. I don't think my laptop is good enough for accurate calibration. But yes I like the area around Rigel and the Witch Head too. Can really see the light reflecting off the Witch Head in the direction of Rigel.

Thanks Josh, glad you like it. I spent many hours working on this image, I have 25 progress versions of it saved! I hope I am not the only madman out there that does that!

Hey Bob, thanks, I am glad you like it. Yes, same gear used (Canon 6D, 70-200mm f/4. I stopped the lens down to f/5.6 to reduce CA and coma.

Before you shoot and put hours into an imaging session, just check your settings and see what works for your set up. Some lenses might be ok being stopped down from f/1.8 to f/2.8 for instance. While others may need to be stopped down further. I would expect that you 50mm f/1.8 lens stopped down to f/4 should give a great view with little CA and coma. But you may not need to stop it down that much. Maybe try f/2.8 and see what it looks like, it may be usable at that focal ratio and you will get a lot more light in less time. Hope that helps!

Cheers mate.

Beautiful work. I did something similar several years ago with a modified 40D and the 200mm f/2.8L II USM. It's a great focal length for these targets.

And, I can confirm that with the thrifty 50, f/4.5 is the spot at which the stars at the edges aren't too bad and chromatic aberration is ameliorated.
