I was wondering if you can spot polar faculae in your CaK images? The BAA at the moment is trying to get data this year on polar faculae (solar minimum) however not many of us take white light images. Do you think they would be able to use our CaK images instead?

Maybe? not sure?

Put the reducer closer to the chip. You're just photographing the vignetting,

Looks good Marty!

Personally, no. Lots of people on here have tried the telecentric / air spaced etalon route and it yields results with too wide a bandpass.

That's a great sketch!

Lots of transits Pedro!

Mighty fine full disks. Slow cameras are fine at this scale.

That's a nice collection of images David!

Lovely captures Rainer!

A good looking disk!

Nice image and thanks for the software update!

Nice images!

Number 3 would be my favourite there.

Nice full disk!

Love the transit!

Lovely detail Pepe!

I think this is a great topic and should be one for the library when discussion has finished.

OK, i've created it. Flag up your software topics you'd like migrating and i'll get them moved over.

I'll set something up later on this evening...

Love these raw stacks Marty! But, then you can probably tell from the images I post I err on that side of things with my processing...

You have the etalon combination nailed!

Just floating this out here to gauge your thoughts; I wondered about creating a 'Solar Software' section on? Basically as the name suggests.... So, like the ImPPG abd SSM posts i've got pinned at the moment would have their own dedicated section. I know we've had several similar in the past, so as w...

Thanks Franco, I probably won't use it with the HaT even down at f22. 9fps is way too slow at that scale, it works for full disks but hi res needs a higher cadence.
