two exposures combined with the DMK41 and the 60DS lunt taken saturday afternoon. processed in Autostakkert2 and Registax6 then PS. very average conditions - well mostly below average but you take what you can get, after all it was cloudy most of the day then the southerly came through
edit - added a bit of a heading change from JJJ

Looks good to me David. I don't mind the unevenness of illumination but it's a pity it's not central.

Yeah I agree but until I conquer the DS issue with direction I am shot. ;):thanx:

I have the same uneven illumination problem (not central) but in my case the mosaic cures the problem. I'm thinking the same for you, even though the Sun might fit of in your FOV, not sure?

so each time you move arounf the disk do you change the setting to shift the highlight to what would ba a central part of the sun?

No. What I do is: I get the disc central on the camera chip, I add a heap of gain until I get a burnt/blown out section on the screen, I then tune the filter until I get the smallest section (it's round of course) of burn out & then this PST is tuned. In my case I'm not in control of WHERE on the SUN or FOV it is. Just so happens this burntout section is slightly off centre, but the standard 6 pane mosaic fixes it.
Naturally I turn down the gain again before shooting!

Nice image David, you must be pleased with that. I know I would be.

Certainly getting there David. The uneven illumination can be sorted with a Lunt but it will take a little time to work it out. I found that making sure the entire field is even would require several adjustments to the primary and secondary etalon.

Yes the pressure tuners have to be set just right from my experience and it can take a fair bit of fiddling. Just persist and you will get there.
