The Sun in Ha - 1st September 2011

[PaulKummer]

Still working on my processing technique but I'm quite pleased with how this one has turned out. Let down a bit by poor focusing - when I'm not in a panic about approaching clouds I will spend more time on it:)

Comments welcome - especially on how it can be improved.

Very good start!

I assume you're using the DMK41?

Do you take separate exposures for the proms and surface?

[PaulKummer]

Yes - this was taken with the DMK41 and I do take separate exposures.

This is the routine I use for process with a DSLR or with the DMK41 PST Solar Imaging PhotosbyKev

[PaulKummer]

Many thanks. I will try that.

Hi Paul, I didn't know you'd bought a Lunt! This is a great image. For the disk I wonder if a slightly higher gamma value might have teased out some subtle details but I'm no expert. Nice work combining the proms. I have worked out a new way of doing it but it is a ludicrous palaver and needs thinking about before I start to waste anyone's time with it...

The FOV of the 41 makes buying one unavoidable. Monique is going to love you!!!

Hi Olly,

"Gamma"? I've not got past Beta yet:). I've had a look and it certainly helps the surface but destroys the proms so I will have to go back a fair way. Perhaps a job for tomorrow.

Yes - I bought a Lunt. A slight diversion from the main plot but after seeing your setup Elaine twisted my arm until I bought it:):)

I'm not yet sure about my method of combining proms and surface. I seem to have found a process that works on this image but I want to try some more images and some more ideas before believing in it.

Great combination shot Paul. These are tricky to pull off.

Stu.

Good go there! My only advice would be if that you are doing a shot for disk and proms, on the disk shot back off a bit on the exposure - I think you could be washing out some of the surface detail, and like Olly says, for the disk, use a lower gamma value - will give you more contrast.

[Merlin66]

On the SM60 double stack set up I usually use about 1/120s for the surface and up to 1/11 sec for the proms.

I am just a numpty , all I have done is looked through a PST

I think your image is great

Even better to come in future , well done
