Big foot repro

The great foot in Sagittarius plus M20. A classic FOV, hopefully better than my last attempt. The data is a couple of years old but my PI chops have improved a bit... or so I hope.

FSQ-106ED scope and STL11K camera. 16x300 sec L, 14x300 sec R, 13x300 sec G and 13 x 200 sec B. Processed with PixInsight.

I also have a few hours of Ha and my next challenge is to combine that tastefully.

You can get to a high res version from here: http://www.astrobin.com/full/194975/0/

Thanks for looking.

Cheers,
Rick.

I really like this one. How do you get such a large area of sky with an FSQ 106? Does that CCD have a large surface area?

Thanks, Kevin. It's a full size (35mm) sensor so the FOV is quite large @ 530mm focal length. It's something like 234x156 arcmin. This is actually a crop

Ta, Greg. I'm sure there's room for improvement!

Thanks, Ian. I used to use a little PS for finishing off but my workflow is 100% PI now.

Love it Rick. You've done a great job of taming the core of the lagoon and going deep as well. Did you only use one sub frame exposure duration, or did you 'HDR' it?
Cheers,
Andrew.

Great stuff Rick I agree with Greg and I was just looking at the master Walfgang Prompers page and along with your result here they show very clearly that realistic exposure times definitely do not relegate an image to mediocrity

That's a good reprocess Rick. The colour is very nice, with surrounding field showing off the star fields and dark dust lanes. The magenta blue balance is well handled and does not have that fluro puce cast all over the image. I think the "blue skirt" is about right and not exaggerated as has been seen in recent examples. That reflection nebulosity is very faint and should not have the same value as brighter sections of the nebula. There is a natural feel to this image.

Certainly benchmark image in my opinion. As good as John Gleasons recent image of the same targets if not better.

Thanks, Andrew. All 5 minute subs!

Thanks, Mike! This was captured in one night at Leyburn with the addition of a little extra colour data from home. No opportunity for megadata and none needed. Must be the f/ratio or the aperture or something

Thanks, Paul! I thought I might have gone a little overboard as I tend to do but so far I haven't offended anybody. Will have to try harder

Cheers,

Wow Rick, that is just stunning. Very natural look to it, almost like being in a space ship and gazing out the window. Beautifully processed as usual.

I am currently working on a mosaic of this area.... not sure how it will go......however, I will be extremely happy if I can produce an image that is 1/10th as pleasing as yours.

Must have touched a nerve Mike for you to bother to comment on something I have written. I could well be talking about other images though.

My comments are aimed at how David Malin wants people to respect the light. Started to come around to his way of thinking somewhat.

Thanks Rex! Good luck with the mosaic. They are a lot of fun but also hard work.

Sweet looking image Rick. Real eye candy material with the different flavours of contrast and colour. The rich golden hues of the star clouds top it all off. I'm in admiration of your PI knowledge. I dice in and out of the app for specific tools which is working well for me, yet I realise there are a plethora of PI tools I have no idea about. I try them out and watch them butcher and mangle the data. I figure its more trial and error, then once you finally nail certain settings, save the process to the workspace so it can be used again. Kinda like learning to walk.

Thanks very much, Jase. I'm familiar with enough PI tools now that I can usually get something approximating the mental picture I am chasing. I still only use a small subset of them. I think that learning a small set well and then adding new processes and techniques one at a time is the way to go. I enjoy the challenge of nutting out solutions to imaging problems and then testing them. Things don't always go as planned but you learn a lot from that experimentation.

Cheers,
Rick.
