Lovely, I wish my processing was as good as that, I've improved since your talk last year. Of course I need to be able to see the sun....

Nice to see the Sun, it's been a bit elusive recently.

Yes it does help somewhat - i have had a 13 day drought.

if you are going this year pop round with some of your data and we will have a little play.

We'll be there all week. I'll have to dig it out.  

Thanks

Very nice.

What set-up did you use for this particular picture?

Can you tell me the resolution in arcsec/pixel?

A fine looking disc.

I am looking for a set-up having your capabilities to reveal all stunning flares and protuberances on the Sun but everything at a resolution of 1 arcsec/pixel.

Can you give me a hint?

Lovely images! Nice bright prom on the right-hand limb, really nice detail.

as I said mine runs at 1.42 arcsec/pixel so you would need something with either samller pixels or longer focal length or get a barlow or power mate to work without Newtons Rings

 

You also need a larger chip than Flir Chameleon as Sol only just fits on it at that scale  or you will need to do mosaics

I use a Skyris274 on my Lunt LS60 if I use a 2X Barlow it gets me .91 arcsec/pixel but the Sun only just squeezes on to the sensor when it's at it smallest leaving no room for proms.
