NGC6188 and 6193

[Bart]

Howdy,


I have never successfully shot this before and with the snatch and grab of data between the weather fronts, this is as good as it gets for the moment.


One in HaLRGB and one in only LRGB. My star processing skills are on the up although I still have a way to go with that.



I hope you enjoy the view.

CHeersand clears!

Great stuff Graham. Nice to see a conventional treatment of this object showing so much detail.
I particularly like the HaLRGB version.

[Atmos]

Very nice. I personally prefer the LRGB the Ha blend has affected some of the reflection nebula and it is kinda novel to see the obscene number of stars scattered throughout this field :thumbsup:

[Placidus]

Well done! The HaLRGB has (somewhat to my surprise) captured the wonderful OIII shock fronts around the super-bright cluster, and even the individual stars in the cluster are more obvious, by virtue of not being burned out. The fainter features including dust lanes are handled with subtlety.

A lovely image.

Seeing both versions is educational - there are squillions of stars.

Do you perchance have an OIII filter?

Well done for getting an image down Graham, we have all been there...bloody weather :cloudy: :scared: :lol:. The HaLRGB certainly gives the impression of some extra detail but the blending is a bit off. The LRGB, however, is a very good mage, very natural and nebulous and, as you say, your stars look good. More of us should shoot this nebula in more natural palettes like this, it really is quite a lovely bit of sky in RGB type colouring. Here (http://www.robgendlerastropics.com/NGC6188MosaicM.html)is a great example and yours isn't too far off this either Graham, top job :thumbsup:

Hi Mike, thanks for the feedback. I struggle with Ha blending, I don't really like the tools in PI and the results and I didn't have the will power to drag out Photoshop and try it in there.


I might give it another crack, then again, I'd rather wait for the weather to clear so I can do a full narrow band of this.


Thanks for your thoughts on the LRGB, it is the one that I like the most as well. :thumbsup:





Hi M&T, nice of you to comment. The shock front is not as obvious in the stacked LRGB frames but it is there as well. I do have an OIII although I have only started using them again as I needed to work out the offsets for focusing which is now complete.



I think you are suggesting some inclusion of OIII or perhaps a bicolour?





Hi Atmos, I do agree about the reflection nebulosity, that will be my clumsy Ha blending.


I could not find a great number of LRGB images to go by although the ones I did find did also show a huge number of stars across the field. :)





Cheers Retrograde, nice of you to stop by and have a look. I think the conventional one is my favourite also. :D

Very nicely done Graham! The LRGB version in particular is compelling and looks pleasingly "natural". :thumbsup:

Adding the Ha can be tricky but essentially it should add to the LRGB and not take anything away. EG: reflection components and smaller stars. You can use the Ha mixed with the luminance to reduce the larger stars though.

[Bart]

Thanks Marc, both for your kind comments and advice. :)

[multiweb]

Very nice. The LRGB stands out for me too. :thumbsup:

[Bart]

Hi Marc, yep, the LRGB is a definite winner. :D

[Ryderscope]

Good work Graham. I agree with the comments on the LRGB version. Nicely detailed and shows the area superbly

[Slawomir]

Great work Graham

[Bart]

Thanks, Ryderscope. The LRGB is definately the pick. :thumbsup:






Cheers, Slawomir, nice of you to have a look. :)
