Re: new spot and intens prom in several freq

WO apo 66mm F5.7
I think Mg is good both visually and photo
I use polarizing filter for more image contrast
of course proms are almost impossible to see in all other wave lengths except Ha , Hb

unless they are flare types

I was happy that I did pick up prom in Mg although very faintly

Re: new spot and intens prom in several freq

yup a subdued metal line but i like it
easy to see even more than caH line


the spectrograph verifies what mg filter sees and visa versa

Re: new spot and intens prom in several freq

looks like other metal lines
easier to see visually
although a bit subdued in intensity
i was surprised that i recorded a prom
even a faint one
i find using a Polarizing filter
rotated to optimal position increases contrast
got a good deal at neaf

Re: That orange PST Rust / A Fungus?

that's oxidation not fungus starts at edge and works inward
I had same problem
replaced filter

older filters were not sealed at edge and their fate was sealed (no pun indented)

Re: The Double pass idea...

I played around with this idea a while back

didn't do much for me
but I most likely missed something and did something wrong
