Imaging with a T300, now in CaK

Post by allhoest »

Again, non favorable conditions this morning, with a cloud raising above the observatory (St Véran, French Alps) from ~8:30, then keep staying above our heads. It looks to be local meteorological phenomenon...

I could save one pic at ~8:00.
And then after patiently waiting, I could get an other one at 10:45 before stopping.

Superb images, Alex, specially considering the conditions ! The detail is incredible. Are we going to see some images from Fred and Christian ?

Superb images, Alex. Very nicely resolved penumbral features and granulation.

Very nice, what CaK filter are you using?

Thank you Franco.
Fred is testing different setups.
Christian, was imaging planets. He will probably move to solar soon.

Thank you.
I'm using a modded Lunt; the original front filters are removed and I use a KLine instead as pre filter.

What is the reason you prefer the K line filter vs Lunt's pre-filter?

Hi Valery,

I have more flux with the KLine as a prefilter (~70% transmission), compared to the front + middle filter of Lunt's CaK module.
There are spectro measurements of the Lunt prefilters in this forum.

More explanation please.

Also, how did you cover the front of that Newt 300mm? I mean for CaK i don't know any frontal ERF, and a reflection that big sure needs one.
