Solar continuum filter

Hi all,

I was wondering is anyone is using one of these filters to view the Sun (in
tandem with a white light filter).

e.g. http://www.firstlightoptics.com/prod...prod=bsolconti


Are they any good?

I've seen the Baader SCF available from many dealers and hopefully someone
can give an honest opinion about its performance.
How useful are they with a DSLR?

I'd be unhappy about anything meant for use as an eyepiece threaded fitting,
even if intended only for use in conjunction with a white light filter on
the front of the scope. Sooner or later someone may cause themselves a
serious eye injury by omitting the front filter over the objective.

I am inclined to agree.

I am not convinced that it would be noticeably better than a Wratten 74
(mercury green line) filter (or cheaper a green Wratten 58).

It is essential to have the Baader film on the scope as well though. For
photography Baader also do a less dense film that is camera safe, but
**not** visually safe. It allows shorter exposures that will help freeze
the seeing.

As ever take care when observing the sun with a telescope - you only get
one pair of eyes.
