M20 narrow band

allan gould · #1 27-06-2010, 12:53 PM

This is my first composite narrow band shot of M20 after I managed to get the O111 and S11 data needed for it.
15x10 min each filter through a 10"SCT with f6.3 focal reducer.
Brisbane weather and my processing skills are a deadly combination against the imager - but I present it as is.
Comments more than welcome.

Wonderful, Allan. Looks sharp as. Gotta be happy with it.

Nice first NB attempt Allan. Was this with the 10" SCT without the reducer?

Well done unusual colouring

Troy, Peter, Trevor
Thanks for the comments but I thought that I would post a reproduction/reprocessing of my data by Martin Pugh which is far better in my opinion than my effort. His handling of the data is so much more sophisticated than mine as it brings out the subtle dust present as well as a far better general appearance.
Thankfully he is going to pass on the Master's secrets to Grasshopper who will sit patiently trying to do as well.
I apologise to him for the jpeg constrictions to his data as that would not be how he would present it.

I like this Allan. Great detail. It has come up a treat for sure.

The repro sure does bring out a lot of detail. Hope you can let us all in on the processing secrets.

I like the second image. It goes to show that the data is good and that some time must be spent on processing techniques. Like all of us mortals.

Doug, Peter and Paul.
I have to agree with you both, data was OK for the equipment (that can improve) but Martin certainly touched it with his special magic.

That's brilliant ! Lovely renditon of this target. Smooth and sharp repo.

The data is certainly there Allan. You have produced a very nice image.

Garyh · #12 04-07-2010, 04:40 PM

Very nice M20. Martin has certainly pulled up some fainter detail for you..
Good data always makes a difference!
Now a re-Pugh with some lessons please!

As soon as Martin posts be the processing details I will attempt my own version using this data. But I dont expect it to be as good. Im reading what I can on the net about processing but the more I fiddle with it the more I go round in circles.
But thanks for the comments Gary, Barb and David and Dr Paul - most appreciated.
