Solar continuum filter

[Craig.a.c (Craig)]

I have observed the sun a number of timers with a solar film (badaar film I think it is) and find it is only good when sunspots are on the surface, I don't seem to be able to see anything else.

I was looking for other types of solar filters and came across this: http://www.myastroshop.com.au/produc...sp?id=MAS-019R. I know it has to be used with the solar film as just a screw in eyepiece to observe the sun is very bad.

Has anyone used this type of filter along with the solar film? If so what other features am I likely to see?

Cheers - Craig.

Anyone?

Nope I've neither seen it nor tried it...

It's basically a green filter which passes a narrower range of wavelengths than a normal green eyepiece filter. I can see it making a difference with an achromat or semi-apo refractor, but if you're using the reflector in your signature it's probably not worth spending money on. You could try an ordinary green eyepiece filter - I find the image too bright in 4" scopes and the green filter tones it down a bit.

If you decide to buy the continuum filter Andrews has it for $114.

I tried all the filters in my box - all the coloured from light blue to red, all the LPR ones and all the narrow band Hbeta/ OIII/ Ha etc trying to find the "best" filter to improve the contrast while viewing in white light.... and the winner is.......The Baader Solar Continuum filter! It does what it says on the box - improved VISUAL contrast. A green filter comes a close second. I now have both the 1.25" and the 2". Just fit it to the nosepiece of the diagonal and forget.
(Doesn't do that much for imaging..... a small pixel camera (DMK21) and a f ratio >30 works MUCH better)

Thanks for the replies everyone.
