Big Spot White Light 24.5.16

[Macavity]

A good day, whatever. Many different scope settings tried... among these
a Mak150 White Light. Quickly pushing the processing (too?) hard gave:
(I see it needs a slight cropping to tidy the edges at very least!)

great shot Chris, its been quite a dynamic sunspot, great to image,i think sols going to look a bit bare for a few days.well done,thanks  charl.

[Macavity]

Thanks Charl... I sense there is MORE to be seen. But my poor old (Mk I Gold) MAK150
has suffered a lot of "kicking around" over the years and may not be well collimated!

Just for fun am trying an O(III) "green" filter. Sold my Baader white light solar Filter.

Looks good to me,  worth trying a No58 filter if you have one.

Nice image.

[sooot]

Very nice

[Macavity]

Used to have a #58 too at one time. lol. Bit inconclusive with the O(III).
Managed to tease a more background out by using contrast masking...
Of course the image tends to look a bit less "dynamic" as a result.
So many processing possibilities, so little time... 

For more surface detail, I had planned to get a double stacked CaK filter.
But these seem to have become a rare(r) item, these days...
White light is certainly a challenge in subtleties?

Nice shot Chris. Looks a little bright, possibly a little over exposed (far be it from me to tell an experienced member of the forum that their image is over exposed )? The OIII filter should help keep the brightness down and keep the exposures sensible. I played around with using an OIII for a while but found it too dark with the ND5 film. When I get around to making a filter from the ND3.8 I recently acquired, I will try it again before spending on a solar continuum filter. I know of at least one member of SGL who uses the OIII (or at least did) on all white light solar images and gets superb results.

[Macavity]

Yes, I think I am consistently over exposing things!  Using FireCapture, I tend to set the
upper edge of the real time histogram at ~90%... But I'm winding things back a bit now!

Yes, I didn't come to any conclusions re. the O(III). Somewhere among my manipulations
I may just have accidentally introduced a ND2.0 (1%) filter! But not in the  images here... 
(Actually the ND2.0 was being used with my Watec Video Cam, to tame (even) ND5 Film!)

Looks OK to me, just pray that something appears next week or WL focusing could be a bit of a problem
