Hi Dennis,

This type of Photography is what I expected to get when I bought a QUARK as well as a QUANTUM PE 0.4Å but the only thing I got was a look into a porridge bowl ...

Hi,
i think i know what you mean.. it really took me a while to find a reasonable Quark and get it running. Now i hope it doesnt break soon :D
What was the problem with the Quantum?

btw: in German "Quark" means curd cheese :lol:

Entschuldigung Dennis ...


OFF TOPIC

Moderators, if this is out of place please delete ...

Interesting that " Maize Grits " which looks exactly same as the Italian " Polenta ".

BTW in Germany there we have also Maisgrütze made from Maisgrieß :o

The best resource you have in high resolution imahing of the sun in H-a is significant aperture increase (8" or larger).
The limit of a 150mm aperture has been reached. And processing is excellent, leave nothing to wish more.

Thanks, means a lot to hear from you.
Yes, i am now looking for options in the C9 region, upgrade my existing C9 with a d-erf or getting a dedicated solar C9.
I heard about the sad news with the loss of the production facility of your company : (
Be safe, if you consider a move to germany and i can help in any way let me know.

Dennis,

Tell us, please, have you applied a Flat Field correction for these images?
If yes, do you have images taken with this Quark sample where no FF has been applied? Such images will show a level of this Quark uniformity.

Stupendous images - it's like like looking at raw snarling power seeing the sun like that in images - what's it like visually?!

WOW ! These are pretty incredible. The contrast is magnificent. Is this using the Evostar 150ED ? or the achromat ?

Valery
Yes, i did a flat field correction, but actually with the -5 dial setting it is not too bad without ff. Im mainly doing it for to get rid of the dustspecks on the camera.
Here now 3 captured images without ff calibration, different gain settings, no editing:

Thanks for these images, Dennis.

This Quark is really good within this size of the FOV.
