Ive wanted to get a nice rendition of Orion for ages but its one I always overlook as sky time is very precious in the UK and there is always something else to get. Its got to be the most imaged target in the sky but is it easy....I dont think so. The colour and tonal range is massive making it a huge task to process. It took me around 12hours to process this one.  Imaged in one night with my AG12 F3.8 Newt and Starlight Xpress H35, conditions were variable with light haze hindering the session, but to be honest I'll take what I can. We have had another very poor winter season with partial clear skies and rain as most of you already know. Exposure times were. 4x900 Ha 1x900 in R 4x840 in B 4x620 in G. Core exposures in RGB were 30s.
 Managed to increase the red signal with the H-alpha frames. Not Ideal but it is what it is! Calibrated with DSS, processed in Photoshop CS3 and Lightroom.

thanks for looking2077467973_OrionNebula2.thumb.jpg.ff8f3113c48988c884b1513e6eb6adc4.jpg

I think you nailed it!

Impressive amount of faint dust revealed and I think the colors are great.

I am always impressed when someone leaves an image up in full res and it doesn't disappoint.. I hope to do that some day! :)

Top right there is a faint blue line going towards the center, is it a diffraction spike or a satellite trail?

Thank you jjosefsen. Its a Satellite trail that needs attention in one of the blue frames.

It is certainly the most popular target, and it is a beautiful sight indeed, but not often you see so much detail.

You have definitely captured fantastic image and one to be proud of.

Thank you Steve

Yep - superb result Peter. Those Powys skies are truly great when it stops raining (My wife comes from nr Newtown - when we used to visit her parents, it rained every single time, except once when it snowed! ? )

Brilliant details! Are the diffraction spikes natural?

All natural spikes...not a fan of artificial ones.... The AG12 does suffer with big spikes...but i quite like them.

One to be proud of, very nice indeed, particularly like the dust captured and processed to produce exquisite detail.

It is why I asked as they look very subtle, unlike artificial ones. Very nice!

Beautiful picture, Peter. Lots of detail.

Mention of your diffraction spikes made me look closer. I've never really paid attention to mine before but the way your 'x' are orientated at 45 deg to horizontal, really adds to the aesthetics. Was this planned? Mine are always at random angles.

Regards

Thank you for noticing that David. It was planned and I always do it that way. Rightly or wrongly I like my FOV to be North South orientated.

Originally the spikes on the scope were turned so that I was able to position the camera N/S with out them running along the columns of the sensor. That way if I'm to use a camera without anti-blooming gates i am able to remove the blooms without damaging the spikes. I used to have an FLI camera without gates and spent ages repairing them.

Practical and aesthetically pleasing in one!! However, now you've given me even more to add to the long list of things to think about when we have clear skies again.

so few subs...

Not out of choice...I only managed 1x15min  red sub.... but adding it with the Ha helped increase the signal...so I got away with it.

It really isn't an easy target to process and I couldn't agree more.  You've masterfully treated your data Peter - great dust, star control and colour.  Beautiful.

Thank you Barry, That means a lot coming from such a seasoned imager as yourself :thumbsup:
