Horse Head M42 weildfield 200MM CANON

[Phil]

Hi took this photo last night with my new canon 70-200mm F/4 lens attached to my STL-11000M. The processed photo has to be done again as i am not happy with this one.
HA/30mins RGB 30mins each channel.

Wow, now that is a widefield! Incredible amount of detail and REDness!

Can you take any shorter exposures (and mask them) to reveal some detail in M42 as well?

[Phil]

Yeh thats why i am going to reprocesse this photo.

Stunner Phil!
There`s no way you could ever get that deep with a DSLR!
You will miss your 11000 M when it sells.
cheers Gary

Nice work Phil. Colour balance is a little out of whack (pink tones), but you've picked up an immense amount of nebulosity. There are a few other ways to approach the dynamic range. If you crop out M42 and perform a DDP on it, the recombine it (blend) into the wide field shot again you'll get the result I expect you're after. Make sure you feather it though as the transition will need to be smooth. Look forward to seeing the next rendition. Nice "first-light" for the lens too.

Fantastic depth Phil.
Can't wait to see it re-processed.

[Phil]

This 70-200mm lens is a killer lens for wield field work. I am going to take sorter exposer tonight to bring out the core of M42.

Fantastic amount of detail/data in that pic Phil.
That is a great lens.

Very wide field shot ! The extended nebulosity around horse and flame region is particularly impressive.

Where did you get your canon lens adapter for the SBIG from Phil ?

I would like to get one for my ST2000XCM because I have a selection of FD lenses that I bought 20 years ago including a FD 70-210mm F4 and a FD 2xB extender and I'd love to try some imaging with them. I saw them advertised on a US site but it said they would not supply to Oz.

Cheers



p.s.
I've attached an adjusted version of your image, hope you don't mind. I adjusted the levels mid range down to 80 then duplicated the layer and applied it as multiply at 50% opacity in PS. Nothing fancy, look forward to seeing your re-processed version.

[Phil]

this is where i got the lens adapter not cheap.

Thanks Phil, I'll check it out !

Get one from a local lad, Steven Mogg makes them, and from memory they are about $60. I have one for my EF lenses.

[Phil]

i ask him to make me one for the STL-11000M and he was not able to make it. He was the first place i looked.

Phil,

I like it!!!!!!!!!!!!!!!!!

I love seeing the amount of nebula that is actually up there! Thank you

wow, 30 minutes with a 200mm lens

You've already got the data Phil. I used your previous post of M42 to "bring back" the missing detail. Rather rushed effort. Could have done a much smoother job with the originals, but this suffices to prove my point. Three words - "Long live Registar".

EDIT: Forgot to attach the "mini" M42 I used for the luminance which was scaled to fit the wide field version. Please excuse the colours on the reprocessed ver as it was done on a dodgy laptop. Data scaling opens up a world of possibilities. The resolution benefits you can obtain scaling down data from a longer focal length instrument is remarkable - in many cases better than taking the shorter focal length luminance. Of course you can go the other way and up scale the data, but I'd only recommend doing this for quality noise free chrominance data.

[Phil]

getting there hear is another reprocessed.

Great image Phil = to be proud of.

Hi Phil

Wow - a not often seen view and quite an incredible image of this fascinating region.

Cheers

The reprocessed version has significantly decreased the "white point washout". Well done Phil.
