That's a beauty Freddie! What equipment did you use for this?

[ffellah]

Excellent shot !

Excellent WL image Freddie

Excellent Freddie.
I come with the same question: can you provide details about your setup.
Thank you.

That's some nice granulation there, Freddie. Looks great.

WoW!!! Awesome!! That is one of the best solar granulation convection images I have seen on here. That's some insane resolution. What scope/equipment did you use, Freddie??

I bet some colorization and contrast adjustment would bring out even more detail.

Thanks for your kind comments. Posted in a bit of a rush this morning so sorry for the lack of info.

This was taken from my back garden in Kent using my CPC9.25. I use Baader 3.8ND film (I also have some 5.0 but the 3.8 is so much better for imaging) a 2x Barlow and my ASI120mm-s. I have locked the std focuser and added an aftermarket focuser to the VB. With everything in place this works out at ~5m FL. Captured using FireCapture then processed in AS!3, Imppg and PS.

Thanks for your kind comments guys.

Freddie,
Was you using a continuum filter?

This really is superb!! I get weak at the knees when I see beautiful granulation

Thanks for your kind comment Alexandra.

James, this isn’t with a continuum filter. I have one in my filter wheel but have never got on with it. By it’s own or with an IR cut we just never clicked.
What I found was that using the Baader green filter (it’s the manual filter wheel I use for planetary imagining so has a full set of Baader LRGB imaging filters along with various others) gave better results. The green filter is centred roughly at the same wavelength as the continuum but has a wider band. I found that the loss of some contrast, which wasn’t much to be honest and can always be compensated for in post processing, was far out weighed by the greater light pass the filter gave, allowing significantly shorter exposures and or lower gain settings. For me, the ability to reduce exposure/gain was far more important at the image scale I use than a bit of contrast. The other critical thing is to use the 3.8ND film as the 5.0ND just doesn’t allow enough light through.

Great results Freddie, thanks for sharing them.
