Nice. 540nm filter?

[fedele]

thanks

hi DeepSolar64
if you are refering to FC100Dl images as writed i'm using a Baader 3,0 ND 2" in the Herschel Prism and baader Solar Continuum 2"

in the baby-Mu image i'm using the Baader ASTF 180mm (full aperture), Baader Astrosolar filter OD 3.8

[DeepSolar64]

The Baader Solar Continuum 2" filter is probably 540nm green.

Oooh!! very nice WL images

I think you could do with a blower on your camera chip, this is much easier than doing a flat
