The Horse Head Nebula in LRGB and Ha Pier 12 was created by petershah

LRGB and Ha The Horse Head Nebula In Orion. Imaged with Pier 12
36x 600 in Luminance and 12x 900s in each RGB total 15hrs. High haze effected some of the data but the weather in Spain hasn't been at its best this winter.
Thanks for looking…

Super detail Peter, I cannot think of anything else an image could need. Great stuff!

Incredibly detailed Peter. You're a master of extracting details without introducing noise, or perhaps I should say a master of noise suppression as well. 

I'd be on cloud nine if I could get anywhere close to that. I'll eventually get around to trying that one when I've found better ways of dealing with certain issues I struggle with. 

Brilliant gallery images Peter, all first class. I know that it's way too much to ask Phil for, but it would have been nice if there was a separate gallery section for novices and the over 70s. That might encourage us mortals to participate.  Steve did point out that it was him that gave you your moniker, but it is well deserved.

Do you still have that early short exposure image of M31, possibly taken 8 or 9 years ago. I think it was the manufacturer AG that used your image in an advert. Not much wrong with my longer term memory if I'm correct. 

Best Regards, 

Ray

Thank you Ray....Ah yes  Steve and the 'The Sky God' was just an embarrassing  inhouse joke....I think one of Steve's attempts to keep things a little fun and more casual...

Please do post your images on the Galley page Ray as they are more than worthy and it will soon push mine down the list.

Yes you do have quite a memory I did a lot of development work for Orion Optics on the AG and still have my AG12 at home running in my garden. The image you refer to was done with the AG8 prototype which I wished I never got rid of that scope....but that is the way it is, things come and go......I do still have that image

I have  a few techniques dealing with noise, I've developed over the years....it was only forced by the lack of clear skies in the UK, able to only grab a few hrs of data and having to squeeze every last photon out of the kit. 
Pixinsight is superb and really is invaluable but in my opinion it can be a bit binary, one can get easily lost in numerical values. There is nothing you can't do in it that you can do in Photoshop, however some of the methods to reach the same goal can become quite convoluted. I don't like the way you need to create a preview window to try something out, where in Photoshop has a live preview all of the time. Even if you go a fraction too far with something you have an option to fade it back, so in effect a sort of middle ground. But then Photoshop doesn't have the same ability to correct for say complex gradients like DBE, Deconvolution etc. and making accurate star masks can be a chore....That's why I use both swapping from one to the other during my workflow....anyway I'm rambling now...lol

Peter,

Thank you for taking the time to explain how you approach your image processing. I think I probably do carry out too much using pixinsight so I'll consider swapping between that and Photoshop more frequently. I'm going to revisit a couple of older projects and see if they can be improved by using Photoshop instead. I'm also a relatively new convert to Photoshop so it will be a good opportunity to learn more of its capabilities. 

Kind Regards,

Ray

Very nice Peter.  That is one way to deal with Alnitak!

Just me, keeping the "Sky Gods" feet firmly on the ground as always :)

PS Ray stop telling him how good he is, as doorways are not that wide!!

Please ignore my dylexia wherever possible, just be thankful I can control my Tourettes ;)
