A happy little Trifid

Here is a happy little image I took most recently. The tilt was not fully corrected on this image but it came out fine anyway.

Ha LRGB 30 minutes 110 40 40 40. Colour binned 2x2.

Lovely! The background Ha and open cluster complement it beautifully

Looks great Greg! Very nice rich field

It seems you don't need another wide-field scope - I would be happy to help you in ridding of the surplus one - the 4" guidescope

Cheers Chris. Its a lovely area. I wasn't sure if I could get a wide view without showing the Lagoon in it.

Hehe. I nearly have all the bits needed to use it. Perhaps a 100 hour Helix is the go!

I am also thinking it may complement the RHA. I could get colour off it and combine it with luminance and Ha from the Honders.

Greg.

Cheers Tim. I also have some recent CDK data I might add to it.

Looks like Christmas has arrived early this year.

A very colourful and pretty scene indeed

Good to see the Trifid in context, as a glowing cloud of gas against a starry, dusty galaxy of mostly warm-coloured stars. Beautifully done.

Hi Greg,
Beautiful field of view
Maybe it is only on my screen, but the core of M20 looks over-stretched; I've made one run (without mask) using HDRMultiscaleTransform (default, to lightness only), and you can see all stars in it ...

Thanks Ian. I just tried that but it made the Trifid look very unpleasant.I did some HDR toning on the original and its about as good as it will get with this data. It would need some shorter exposures.

I have some high quality CDK17 data which was incomplete due to weather. I'll add that in and perhaps it will be recovered that way. But personally those few little stars blown out in the core don't bother me.

Greg.

I've edited the image from Ian's observations.

I've done some Photoshop devilry where the Trifid now has the body of a Honders 12 inch and the head of a CDK17!

So more detail in the centre areas and a bit more dynamic range.

Same original links:

https://pbase.com/image/169826418/large

https://pbase.com/image/169826418/original

It pays to archive earlier data for adding in later on. Its a multi year approach to getting longer exposures!

This one is now around 15 hours.

Greg.
