120mm full aperture

I was advised that I could use my 120mm celestron with a 1.25mm solar wedge and to try a green filter here are the results not too shabby.

Not bad for an ordinary green filter 👍

Looking a lot better already! Looks like a some high cloud may be causing a bit of scatter. A reasonable green filter should get pretty close to a Continuum in sharpening up achromats for white light.

Looking good Paul. Have you tried an OIII or UHC filter, that would be narrower band that a simple green filter and may sharpen things up. How did it look visually?

I have a cheap light pollution filter which I purchased when a complete beginner. Then discovered it was rubbish for light pollution and shoved it into the back of a cupboard.

However, for some reason it does sharpen up solar, as well as bring out a little more granulation.

Looked really good visually but it was quite hard get fine focus on the phone

Looked really good visually but it was quite hard to focus on the phone. I have both a Oiii and UHC so I can try them.

 Do you know I have a light pollution filter never crossed my mind to try that I will give it a go thank you.

An OIII will have a tighter bandpass so should work better, but worth trying to see which gives best results

It can be fiddly focusing a phone on the sun, especially when there are clouds around. Even more of a fiddle if you aren’t using a phone adapter. If I don’t lock focus then my phone will hunt around for focus (worse with passing clouds) and with any stray light between phone lens and eyepiece. I find it easier to focus on nighttime targets. 

About a year ago I spent one session on the sun running through all the filters that I had, just to see if there was any difference. At the time I did have a rather cheap OIII and the light pollution filter gave better results. However, I now have a decent OIII - an Astronomik - which I haven’t yet tried on solar.

I have an adapter this one. It does pretty good but it needs fine focus. You get the two rubber pieces which fit most eyepieces.
