false Colour Sun

[trent_julie]

Hey everyone,
I have finally completed a project I have been working towards for some time. to complete this picture I had to first obtain all the equipment which has taken effort alone.

Featured is a composite image of the Sun
Red being Hydrogen Alpha Light from a Coronando PST
Blue being from a Lunt Calcium Telescope
Both images obtained using a DMK-41 Camera.

I hope you all enjoy this image as much as I've enjoyed the challenge of obtaining it.
Cheers,

Trent

Interesting combination Trent. It takes a bit to get used to seeing the Ha and CaK together like that... I don't know why... narrow band seems to work for DSOs - less "unusual" or something...

This is my attempt of thinking outside the box, I have a feeling this is going to be one of those "love it or hate it" pictures

Yeah, I think you know what I mean...

Actually, have you tried putting the CaK in the green channel instead of the blue? I know the CaK is actually blue, but I'm just wondering if its the purple colour that makes it seems strange... put the CaK in the green channel will result in a more yellow image rather than purple.

I'm not sure if its a simple "psychological" effect like that or if it the different detail in the two layers contrasting rather than complementing each other.

But I do appreciate the idea!

Al,
I have made a quick version as per your suggestion,
Thoughts would be appeciated.

That's a cool shot. The bicolor process really enhances the various features. I had my first look through a solar filter on my ED80 this arvo and I recognised those spots straight away. Was all excited so I called SWMBO who said "yeah... what I'm looking at? Why is it all orange. Your scope is dirty. There are two bugs on the lens..." Can't win.

Cheers Multi,
Solar observing can be a path of addiction, be careful............

One last go......

[MarkA (Mark)]

All systems go. As far I can see go very well

Congratulation guys on lovely almost 3D image well done in did.

Regards Mark

Thanks Mark,
I think the last blending achieved that 3D effect....
Cheers
